Knowledge about enamelled wire

Enamelled wire is the main raw material of wire wrap for products such as motors, electrical appliances and household appliances.

It is a winding process for the production of raw materials.

No special instructions winding machine winding is enameled wire.

The enamelled wire consists of a conductor and an insulating layer. Conductor material should be alloy copper or aluminum; The insulating layer is composed of various resin paints.

Commonly used enamelled wire classification

QA Polyurethane enamelled Wire (UEW)

UEW is polyurethane enamelled wire, usually used to mark class 130 polyurethane enamelled wire,

For example :UEW/130, 155 level to add M, such as: MUEW/155

Composition: Copper conductor and polyurethane resin

Features: easy dyeing, direct welding, low medium loss at high frequency;

QA(polyurethane) : easy coloring, good high frequency performance, because it can be welded directly without paint, so the work efficiency is relatively high.

QA= polyurethane copper wire, heat resistance index 130 155 180

Polyurethane enamelled wire has an advantage that other types of enamelled wire cannot match, that is, direct weldability.

The so-called direct weldability is a performance that the enameled wire is welded directly without scraping paint when soldering.

It greatly enhances the flexibility of customers' winding coils and saves costs, so it has won wide acclaim since its launch.

QZ Polyester enamelled Wire (PEW)

PEW is polyester enamelled wire, usually used to mark class 130 polyester enamelled wire,

For example: PEW/130, level 155 should add M, for example: MPEW/155

Composition: Copper conductor and polyester resin

Features: Good mechanical strength, film adhesion, excellent electrical, scratch resistance, chemical resistance, thermal stability and solvent resistance;

QZ(polyester) : Excellent heat resistance, excellent solvent resistance, excellent softening and aging properties. General transformers use polyester enamelled wire.

The higher the voltage, the thicker the paint film used.

QZ= polyester, heat resistance index 130 general 155 domestic called QZG, the current domestic 130 is equivalent to IEC 130L clas

QZY polyester imide enamelled wire

Heat resistance index 180, good modified products can reach the general sense of 200.

General composite polyamideimide, as 200 line primer, single coating, salt water pinholes are not ideal.

High-temperature enamelled wire, as the name suggests, is a enamelled wire that can withstand high temperatures.

The general enamelled wire is temperature resistant at 130, 155, and can reach 180, which is already quite high.

High temperature enamelled wire, in addition to the previous three specifications, can reach 200, 220 or even 240 levels.

Each level represents that the enamelled wire can be used for a long time at this numerical temperature.

Product specifications line diameter can reach 3.5mm, the main production QZY,QZY(XY),QY and so on.
