Characteristics of enameled wire
- Jan 11, 2018 -


1, acetal enamelled wire, thermal level 105 and 120, with good mechanical strength, adhesion and resistance to transformer oil and refrigerant performance, but the product moisture resistant performance is poor, thermal softening temperature low breakdown, durable benzene - alcohol mixed solvent performance weak, only a few used in oil-immersed transformer, oil filled motor winding.

2. Polyurethane enameled wire;

The thermal level is 130, 155, 180 and 200.

The biggest characteristic is straight welding resistance, resistance to high frequency performance is good, easy coloring, moisture resistant performance is good, should be widely in electronic appliances and precision instruments, telecommunications, instrumentation, this product weakness is a bit poor mechanical strength, heat resistance is not high, and in the production of large size line flexibility and adhesion is poor, so the product of the specifications of the production in small and medium-sized and fine lines.

3. Enameled wire of polyester and modified polyester, the heat level of ordinary polyester enameled wire is 130, and the heat level of the enameled wire is 155 after modification.

The product has high mechanical strength and good elasticity, adhesion, electrical performance and solvent resistance. The weak resistance is the poor thermal shock resistance and low moisture resistance.

It is one of the largest varieties of production in our country, accounting for about two-thirds, and is widely used in all kinds of motors, electrical appliances, instruments, telecommunications equipment and household appliances.

4, polyester imide/polyamide imide enamelled wire si composite layer is widely used at home and abroad of heat resistant enameled wire, thermal level 200, high heat resistance, the product has a refrigerant resistance, cold resistance, radiation resistance and other properties, high mechanical strength, electrical performance stability, good chemical resistance and freeze resistance performance, overload ability.

It is widely used in refrigerator compressor, air conditioning compressor, electric tool, explosion-proof electric motor and high temperature, high temperature, radiation, overload, etc.

5, polyester imide/polyamide composite enameled wire, thermal level 180, this product has good heat impact resistance, resistance to soften the breakdown high temperature, excellent mechanical strength, resistance to solvents and refrigerant performance is good, weakness is easy to hydrolysis under closed condition, it is widely used in heat resistant requirements of high motor, electrical appliance, instrument, power tool power dry type transformer winding, etc.
