Products Description

Name:Enameled Copper Magnet Wire

Structure: Conductor + Insulation layer

1. Conductor: Copper enameled wire

High conductivity, low loss, suitable for high-performance motors and transformers

Aluminum enameled wire

Lightweight and low cost, often used in applications where cost and weight are critical

2. Insulating varnish layer (critical)

The varnish layer is very thin, but the performance requirements are extremely high. Common types include:

Polyester (PEW)

Polyesterimide (EIW)

Polyimide (PI)

Polyurethane (UEW)

Feature
1/High conductivity and durability
Our Enameled Copper Magnet Wire are made of 99.9% pure copper to ensure excellent electrical conductivity, with a conductivity as high as ≥97% IACS, greatly improving equipment efficiency and stability. Compared with low-purity copper wires on the market, it provides lower resistance and higher energy efficiency.

2/Excellent insulation performance and high temperature resistance
Polyester enamelled copper wire has high temperature grades such as 155°C and 180°C, and is suitable for operation in high temperature environments. It is especially suitable for transformers, motors and other equipment to avoid damage to the insulation layer under high temperature conditions.

3/Adopt precision coating technology
We use fully automatic painting equipment to ensure that every meter of copper wire is coated evenly and has a stable thickness. The outer paint thickness tolerance is controlled at ±0.003mm, which reduces electrical failures caused by uneven coating.
