transformer winding wire

UEW Standard Enamlled Aluminum Round Transformer Winding Wire is a main kind of winding wire. It consists of conductor and insulating layer. After annealing and softening, the bare wire is painted and baked many times. However, it is not easy to produce products that meet both standard requirements and customer requirements. It is affected by raw material quality, process parameters, production equipment, environment and other factors. Therefore, the quality characteristics of various enameled wires are different, but they all have four major properties: mechanical, chemical, electrical and thermal properties.

The acetal enameled wire has two thermal grades: 105 and 120. It has good mechanical strength, adhesion, resistance to transformer oil and refrigerant, and only a small amount is used for windings of oil-immersed transformers and oil-filled motors.

Polyesterimide/polyamide composite enameled wire, thermal class 180. This product has good thermal shock resistance, high softening and breakdown temperature, excellent mechanical strength, and good solvent and refrigerant resistance. It is used in dry-type power transformers, etc. Winding.

Magnet Wire: enameled wire, winding wire, enamelled wire, magnetic wire, conductor covered
Type: copper winding wire, aluminum enameled wire
Application: motors, generators, transformers, and electric vehicles
Thermal Class: 130, 155, 180, 200, 220, 240

5 method to choos the enameled copper wire, like price, voltage, stability and other performance, also can do an experiment to sure the characteristic.

Round Enameled Wire type: Aluminum Wire and Copper Wire
Application:used for transformers, inductors, motors, generators, dry type transformer, Cast Resin Transformers
Dimension: Aluminum : 0.2-9.2mm; Copper: 0.016-7mm

With the transformer and motors developping, the Enameled Aluminum Wire On The Market is used more and more, expecially the unstable price of copper.
Enameled Aluminum Wire Type: rectangular and round type
Certificate: UL

What is the enamelled copper wire? The enamelled copper wire is a wire which has been electrolytically refined; the layer is made from tough polymer materials. As these wires have coating on them they are also called magnet wires.

Springiness of Round Enameled Wire is one of important performance in accordance with the IEC standards to ensure the quality of Round Enameled Wire. How to improve the performance, the article introduce how to operate the enameling machine, during the manufacturing process of enameled wire, the worker shoule be focus on some points.

So far, most of transformer, motors and generator manufacturer used the copper magnet wire with its high performance. Nowadays, the enameled aluminum wire uses widely in low-voltage dry type transformer, and motores, which can gradually the copper wire.
