Business description

Enamelled copper wire is one of the main types of winding wire, which consists of a conductor and an insulation layer.

The bare wire is annealed and softened, then painted and baked several times.

Enamelled wire is divided into flat, round and square types and is used in long-term refrigeration equipment and chemically corroded electrical equipment, dry-type transformers, oil-immersed transformers, epoxy cast transformers, iron spacers, electromagnets and other electromechanical equipment

The enamelled wire is made up of copper conductors and insulation materials, the main insulation materials are UEW, PEW and AIW, with temperature classes of 130°C, 155°C, 180°C, 200°C, 220°C and 240°C.

The colours are natural and aesthetically pleasing.

Types of enamelled wire

1 - Acetal enamelled wire in 105 and 120 temperature classes for windings of oil-immersed transformers and oil-immersed motors.

2 - Polyester and modified polyester enamelled wire with a heat resistance rating of 130 for normal polyester enamelled wire and 155 for modified enamelled wire.

3 - Polyurethane enamelled wire; heat resistance class 130, 155, 180, 200 - Widely used in electronics and electrical appliances, precision instruments, telecommunications, meters and other fields.

4 - Polyesterimide/polyamide composite enamelled wire; heat resistance class 180, widely used in windings requiring high heat resistance in motors, electrical appliances, instruments, electric tools, dry type power transformers, etc.

5 - Polyesterimide/polyamidei mide composite layer enamelled wire is a heat-resistant enamelled wire widely used at home and abroad.

Its heat resistance class is 200 - It is widely used in refrigerator compressors, air conditioning compressors, power tools, explosion-proof motors and motors and appliances used under high temperature, high cold, radiation resistant and overload conditions.
