Mica Ceramic Insulators

Mica ceramic insulators is one kind of complete insulator product made by inorganic non-metallic materials and it has the characteristics of ceramic and plastic materials.

The advantages of mica-ceramic insulators as follows:

1. Working stably in the various climatic environment with high reliability, ageing resistance and long service life.

2. Completely non-flammable, high fireproof grade, high service temperature and the highest service temperature can reach more than 300℃.

3. Excellent chemical stability with good acid and alkali corrosion resistance.

4. High mechanical strength, such as tension, bending, compression, torque, etc.

5. High voltage strength, good electrical insulation performance, high insulation resistance and low dielectric loss.
