The working temperature of enameled wire
- Oct 12, 2018 -

Enameled wire thermal level is divided into 130 grade, 155 grade, 180 grade/level 200, thermal level is the level of heat-resistant, high can withstand 130 °, 155 °, 180 ° 200 ° / temperature, according to the different use of the environment to choose suitable for thermal level of enameled wire.

High temperature is 200 °, the commonly used 130 °.


Enamelled wire refers to the metal wire used as insulating coating and for winding electromagnetic coil, also known as electromagnetic wire.

It is a main kind of winding wire, which is composed of conductor and insulation layer. After annealing and softening, the naked wire is painted for many times and baked.

However, it is not easy to produce products that meet both the standard and customer requirements. They are 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 four major performances: mechanical performance, chemical performance, electrical performance and thermal performance.
