What's the high-voltage porcelain insulator?
2013-12-05 15:52:17

 Porcelain insulator is a high-voltage high-density and high strength ceramics, ceramic composition is relatively pure. Such material can only sit and stable performance. In the case of withstand high voltage is not easy to breakdown.

Manufacturing processes that require high pressure injection press equipment, require a relatively high density of the finished product.
Play an important role in overhead transmission lines. The early years of ceramic insulators used for poles, slowly developing in the high-pressure end of the wire connecting the tower to hang a lot of disk-shaped insulator, which is to increase the creepage distance, usually made ​​of ceramic, called ceramic insulators. Ceramic insulators in overhead transmission line plays two fundamental role, namely support wires and prevent current back to the ground, these two roles must be guaranteed, ceramic insulators should not be due to environmental and electrical load conditions change resulted in a variety of electrical and mechanical stress failure, otherwise it will not produce the ceramic insulator significant role, it will damage the whole line and operating life.
