what are windings in a transformer?

Jun 12, 2022

Enameled wire is a main type of winding wire in transformer. It consists of a conductor and an insulating layer. After the bare wire is softened by annealing, it is painted and baked many times. However, it is not easy to produce products that not only meet the requirements of the standard, but also meet the requirements of customers. It is affected by the quality of raw materials, process parameters, production equipment, environment and other factors. Therefore, the quality characteristics of various enameled wires are different, but they all have Mechanical properties, chemical properties, electrical properties, and thermal properties are four major properties.

A multilayer film aluminum foil transformer is made by winding a conductor and an insulating layer around the magnetic core. The conductor is aluminum foil, and the aluminum foil is separated by an insulating layer. The insulating layer is an insulating film; the width of the insulating film exceeds the width of the aluminum foil, and the aluminum foil margins between different layers No touch; there are metal pins welded on both ends of the aluminum foil, and the distance between the metal pins determines the effective number of turns of the aluminum foil, which determines the relevant parameters of the multilayer film aluminum foil transformer.

The beneficial effects are as follows:
1. Aluminum foil replaces copper wire or aluminum wire, and the film structure conductor avoids the "skin effect" causing the harmful consequences of conductor heating and high energy consumption. It can be applied to high-frequency current occasions;
2. Using thin film as a conductor Insulator, compared with enameled wire, has a lower cost;
3. Compared with transformers of the same specification, its volume and weight are smaller than traditional transformers.

Aluminum Co., Ltd. specializes in the production of transformer winding materials, such as enameled aluminum wire, enameled copper wire, aluminum foil for transformers, transformer aluminum busbars, copper-aluminum composite busbars, which are widely used in transformer windings and serve well-known domestic and foreign companies.
