BACKGROUND

 

 
Network devices such as computer peripherals, network access issues, and IoT (Web of Things) apparatus might have both their information connectivity and power demands fulfilled within one combined function cable such as PoE (Power over Ethernet). Inconventional PoE systems, power is delivered within the wires used by the information within a range from several meters to about one hundred meters. When a greater distance is required or fiber optic cables are used, power is normally provided through a neighborhood powersource such as a nearby wall socket due to constraints with ability, reach, and cable loss in traditional PoE. Now’s PoE systems also have limited power capability, which might be insufficient for many classes of apparatus. If the available power overcombined function cables is improved, cooling might also need to be delivered into the large powered remote apparatus.

BACKGROUND

 

 
In recent decades, there’s been a demand for creating a more detailed temperature measurement in a specific space or region in various fields. For instance, there are a demand for finely measuring a specific region of the human body (forexample, a temperature of the internal periphery of a tubular organ) during surgery or the similar to one the human body, and a demand for finely measuring a temperature in a specific space in a plastic greenhouse or the like. In this case, measurements aremade with a temperature sensor being put on some kind of apparatus such as a cable. As finer dimensions are desired, a larger number of detectors need to be mounted necessarily.
 

 
When many detectors are installed using a cable for a device, the amount of cables for receiving signals from the detectors increases and the increase in the amount of the detectors. This contributes to a bigger finished diameter and poorflexibility. Moreover, there’s a need to explicitly discriminate which core cable is connected to a detector installed at which position. In this aspect, an invention such that the identification is made on the basis of a blend of colours of corewire covering, and the like has been called in the invention described in Japanese Utility Model Application Laid-Open No. Hei. 6-5040, for instance.

BACKGROUND

 

 
Polymer composite materials are used in the wire and cable industry to give insulation and sheathing of electric conductors. Such substances must often meet a complicated variety of electric, mechanical performance and firerequirements, which are based on the specific type of environment in which the substance was made to be utilized.
 

 
In recent decades, the usage of materials comprising a halogen, such as bromine or chlorine, has been limited in many countries. Gases evolved through burning could be corrosive, poisonous, harmful & create thick smoke obscuring escape in firesituations. The potential advantages of halogen-free cables might include decreased ecological and corrosive impact, as well as a possible reduction in smoke and/or poisonous gas generation.
 

 
There’s continuing a necessity to generate polymer composite materials for wire and cable programs which are substantially free of halogen-containing substances while preserving the essential flame retardant and of physical attributes of these cablesheathing materials.

BACKGROUND

 

 
1. Field of the Invention
 

 
The present invention relates generally to electric wire and cable, and more particularly, to the hybrid cable assemblies.
 

 
2. Description of Related Art
 

 
Underwriters Laboratories (“UL”) cable and cable criteria include the criteria for Tray Cable (“TC”) and Service Entrance cable (“SE Cable”). These standards set forth the constraints for building and/or usage of the TC and SE Cable.
 

 
Construction of TC is covered by UL 1277, and is not allowed by code to be set up outside of raceways, direct burialcable and cable trays. It’s not permitted to be set up in a building with no in stated raceway or cable tray.
 

 
SE Cable constructions are covered by UL 854, and is designed chiefly for above ground electrical cable installations to home supply panels or panel-to-panel between multi-family dwellings. SE Cable structure is permitted forinterior/building use and some exterior use without the constraints of raceways and/or cable trays. SE Cable isn’t permitted to be installed underground. SE Cable includes SE-R, or Form R, cable, which further needs at least four (4) conductors forinside use.
 

 
To comply with all the UL standards, electric installers installing both TC and SE Cable (or even SE-R Cable) must purchase these kinds of wire separately and keep these different wire types at the jobsite. Currently, multiple wire types must bepurchase and maintained as one wire type does not satisfy the constraints of the UL 1277 and UL 854 and consequently can’t be installed for the purposes of the two. There are various differences between TC and SE-R Cable are as follows: TC traditionally includes amore robust jacket, but no necessity for a buffer; SE-R Cable requires a fiberglass wrap beneath the jacket to add extra security; and there are also various moisture ratings like a cable must be rated”moist” or”dry” and pass theappropriate temperature and moisture exposure tests until it’ll be permitted in certain areas.
 

 
According to the prior art, two different cable lengths of 2 different cable constructions were required to complete an electrical installation covering both places, or additional infrastructure (raceways, cable trays, etc.) were demanded toaccommodate use of TC everywhere. When using different constructions, appropriate connectors and electrical boxes are required at connection points, raising the cost of the undertaking. Further, costs and time are increased for every wire constructionsat a work website.
 

 
Therefore, a need exists for a hybrid cable that complies with the structure and use requirements of both UL 1277 and 854. Such a hybrid cable would allow setup of a single cable in-place of SE-R Cable or TC with no switchingproducts or requiring additional infrastructure.

BACKGROUND

 

 
Induction heating of workpieces to be welded, for example pipe, frequently entails arranging a fixture or one or more conductive cables in proximity to the workpiece. Conventional heating conductors may be liquid-cooled or air-cooled. Conventionalair-cooled cables are constructed by pulling cables through sleeves, such as a PyroSleeve sleeve, for both thermal and mechanical protection. Pulling the cables through sleeves is a difficult and labour intensive process which restricts the period of cable jacketinstalled. Conventional cables are built with 150. degree. C. magnet wire insulation, that requires additional thermal protection from the warmth of the area being inductively heated, which can reach temperatures in excess of 150. degree. C. (e.g.,the temperature rating of the insulation of conventional cables). Cable manufacturers are able to extrude silicone insulation for a coat, but silicone insulating material is soft, cuts or rips easily, and does not hold up to abrasion.
 

 
There’s a demand for air-cooled induction heating wires that have improved resistance to wear, abrasion, cuts, rips, and warmth.

Making an enhanced magnet wire insulation suited for an electric submersible motor application https://www.inventiv.org/making-an-enhanced-magnet-wire-insulation-suited-for-an-electric-submersible-motor-application/ Tue, 09 Jun 2020 17:25:41 +0000 https://www.inventiv.org/making-an-enhanced-magnet-wire-insulation-suited-for-an-electric-submersible-motor-application/ A system and process for enhanced magnet wire insulation is clarified. The technique comprises a sequence of operations to create an improved magnet wire insulation acceptable for use in temperatures of approximately 550. degree. Fahrenheit. A magnet aluminum cable is wrapped using a polyimide wrap and subsequently wrapped using a natural polymer thermoplastic (e.g., PEEK). The polyimide wrap is implemented while the magnet aluminum cable is around a spool to create a wrapped magnet cable. The wrapped magnet cable can be heated with an induction coil in a metallic tube bolted to an extruder to eliminate moisture and also to enable including the layer of natural polymer thermoplastic. The metallic tube can be held in a partial vacuum to fortify moisture removal of this wrapped magnet wire prior to running the wrapped magnet cable through the extruder which adds the natural polymer thermoplastic layer. This method creates an improved magnet cable acceptable for a wide range of temperatures.

BACKGROUND

 

 
1. Field of the Invention
 

 
Embodiments of this invention described herein pertain to the area of magnet wire. More particularly, but not by way of limitation, one or more embodiments of this invention enable a system and process for enhanced magnet wire insulation forelectric submersible pump software.
 

 
2. Description of the Related Art
 

 
Currently available magnet wire is not suitable for some motor software. Particularly, magnet wire used in motors for oil or gas pumping software ought to be exceptionally dependable. When a motor is utilized in a petroleum or gas well, a wirefailure or short is especially costly as the engine is heavy in the floor. If the insulating material of the magnet wire in the engine forms fractures, these fractures can cause premature failure of the engine.
 

 
In the instance of an electrical submersible pump (ESP), a failure of the engine can be catastrophic as it implies having to remove the unit in the well for repairs. ESP assemblies particularly require the magnet wire used be able ofsurviving the high temperatures deep below ground. Additionally, ESP pumps can sometimes leak, allowing some water to go into the motor. A magnet wire that’s appropriately waterproof so as to prevent a short when exposed to these leakage could be anadvantage in all kinds of pumping applications. At length, magnet wires often are damaged when they are transported, incurring fractures, nicks or pinholes. This damage reduces the life expectancy of this wire. A magnet wire with greater durabilityduring transport would be an advantage in all kinds of magnet wire software.
 

 
Currently available magnet cable is occasionally insulated with polyimide film, such as Kapton.RTM. (a signature of E. I. Du Pont De Nemours and Company) tape. Polyimide film is a sort of synthetic polymeric resin of a course resistant to hightemperatures, wear, and corrosion, utilized primarily as a coating or film on a parasite material. While for brevity this description uses Kapton.RTM. As an example of polyimide film, nothing herein restricts the creation to using a particularpolyimide movie like Kapton.RTM. tape. While Kapton.RTM. Gets the greatest dielectric strength of any cable insulating material now available, it does have inherent weaknesses. Kapton.RTM. Easily takes on water (is hydroscopic) and then degradesrapidly. The adhesive used to attach Kapton.RTM. Tape into the cable may also delaminate at the extreme high temperatures of deep wells. Magnet cable wrapped with Kapton tape can also be likely to damage during transport.
 

 
Another currently available insulation for magnet wire is organic polymer thermoplastic insulation, for example PEEK (polyetheretherketone). While PEEK has sufficient dielectric strength at room temperature, it drops off quickly when utilized above500.degree. F. Motor temperatures at high temperature wells may reach in excess of 550. degree. F. Therefore, PEEK is also not perfect wire insulation for use in ESP motors.
 

 
Therefore, there is a demand for a system and method to make enhanced magnet wire insulation that is more waterproof, durable during shipping and also reliable in the high temperatures for ESP applications.

BACKGROUND

 

 
Capacitive touchscreen displays, such as those existing in smart telephones, rely on the electrical properties of your body to discover when and where on a screen the user is not touching. Because of this, capacitive displays can be controlledwith very mild touches of a finger and generally can’t be used with a mechanical stylus or even a gloved hand. For a capacitive device, the capacitive display is made from an insulating layer that can also be translucent, such as plastic or glass. If theinsulating layer is transparent, then a thin trace of transparent conductive material is utilized to form electrical patterns on the inside of the insulating material layer. When a user touches the monitor with his finger, then some of this fee is transferred to theuser, so the fee on the capacitive layer decreases. This reduction is measured in circuits located at each corner of the screen. The computer calculates, from the comparative differences accountable at each corner, where the touch event tookplace then relays that data to the touch-screen driver program.
 

 
Flexible electronic equipment, also known as flexible circuits, result from assembling electronic circuits by mounting electronics on flexible substrates. The flexibility of the circuit is usually limited not only by the flexibility of thesubstrate, but also by the flexibility of the electronic devices, circuit lines and interconnections mounted on the substrate.
 

 
Conductive layers, circuit wiring and interconnections may be formed using a conductive paste, usually comprising conductive particles dispersed in an organic medium. Present conductive pastes are not suitable for selective structuring atthe micron-sized degree, as required, as an instance, in microelectronics manufacture. In addition, these pastes do not exhibit adequate resistance to environmental effects such as, for instance, extremes of temperature. Conventional conductive pastes maycomprise an epoxy resin. In these pastes, the hardening agent is hard and flaky, a therefore the pastes are not suitable for manufacturing flexible circuits. The electrically conductive pastes are also likely to form a gel after being kept in storage fora long time. Other conventional polymeric pastes have the disadvantage of non-flexibility. As a result, a functional circuit made of conventional electrically conductive paste is likely to crack. Conventional conductive pastes, such as, as an instance,those containing silver nanoparticles or metal complex particles can’t generally be sintered at reduced temperature. Accordingly, as soon as a circuit or conductive layer or interconnection is formed on a substrate using such conventional pastes, damage to thesubstrate may happen.
 

 
There is a demand to get a conductive paste effective at forming a flexible conductive layer, circuit cable and/or interconnection at reduced temperature, which is capable of being stretched with no considerable crack formation or substantial loss inelectrical continuity. There is also a necessity to produce solderable flexible paste for applications such as, by way of example, decorative LED lighting.
 

 
The present invention seeks to undertake at least some of the issues related to the prior art or at least to supply a commercially suitable alternative solution thereto.
 

 
The current invention provides a conductive paste containing conductive particles dispersed in an organic medium, the organic medium containing: a solvent; along with a binder containing a polyester.
 

 
Each aspect or embodiment as described herein may be used with any other aspect(s) or embodiment(s) unless clearly indicated to the contrary. Specifically, any features indicated as being beneficial or preferred may be used with anyother characteristic indicated as being beneficial or preferred.

BACKGROUND

 

 
There is growing interest in incorporating electronic equipment into everyday objects, such as clothing and cloth items which are expected to become pliable, stretchable and soft. Soft electronic equipment would be able to seamlessly interface using the humanbody, opening up many new applications such as wearables, medical apparatus along with the possibility of conformal robotics or’soft machines’ which could more securely interact with humans or delicate things (see, for instance, Dickey, ACS Appl Mater Interfaces. 2014Nov. 12; 6(21): 18369-18379).
 

 
Many unconventional manufacturing methods are used to fabricate these soft electronics, especially 3D printing. However, a major stumbling block is the lack of a high conductivity and easily processed stretchable conductor.
 

 
Many attempts at stretchable conductors are tried. One of the most successful has been microfluidic channels full of room temperature liquid alloy. Functional devices are created by etching micrometer channels intopolydimethylsiloxane (PDMS), sealing them over and then injecting metals alloy into the channels to make conductive paths. These metals may have a melting point as low as -19. degree. C. and so remain fluid under ordinary conditions. Since the metalconductors are fluid, they may be deformed to an extent limited solely by the material creating the channels comprising them and recover fully. Further, their change in resistance is a purely mechanical function of the cable length and cross section and sois linear. This affords a significant advantage of enabling conductive pathways to also act as sensors.
 

 

However.

Manufacturing devices with such microfluidic channels is very challenging. PDMS is your preferred substrate, but producing a proper seal around the channels is costly, requiring exposure of this station comprising layer to oxygenplasma so as to stick a cap coating to enclose the station. Once assembled, the channels must be filled through a two syringe system, where one syringe injects the liquid alloy and the other evacuates the air already existing. Failure rates duringconstruction are very significant. Anecdotally it’s been reported that only about one in twenty five fabrication attempts succeeds. Thus, the need exist for other”liquid” metals.
