Porcelain pin insulator is one main of ceramic electrical insulators used for distribution power lines made from ceramic materials with high creepage distance.

porcelain pin insulator

Ceramic electrical insulators properties:
◆ Anti-pollution resistance
◆ Easy maintenance
◆ Long-term service life
◆ Standard: IEC, ANSI, DIN, GB and etc.
◆ Color: white, grey, brown, etc.

As a one mian type of ceramic electrical insulators, porcelain pin type insulator can be used for 11kV, 22kV and 33kV power lines.

Ceramic electrical insulators needed long-term operation of external insulation devices, designs requirements for service life at least 30 to 50 years.
