What material is a ceramic insulator made of?


Ceramic insulator is a kind of special insulation component, which can play an important role in overhead transmission lines. 

Then what material is ceramic insulator made of ?

Porcelain insulator Insulator made of electrical ceramics. Electrical ceramics are baked from quartz, feldspar and clay. The porcelain surface of porcelain insulators is usually covered with porcelain glaze to improve its mechanical strength, waterproof infiltration and increase surface smoothness. Among all kinds of insulators, porcelain insulators are the most commonly used.

Characteristics: high temperature burning, no fading, no soft, no deformation.

Ceramic insulator is widely used, but in use, ceramic insulator also has its own advantages and disadvantages:

1, high mechanical strength.
2. Good wear resistance and corrosion resistance.
3, good thermal stability.
4. The raw materials are abundant and the price is low.

5, the product environmental protection, pollution-free.

1, brittleness, low impact resistance, hard.
2. Low ability of post-processing.
