Insulators are a special kind of insulation control, can play an important role in the overhead transmission lines. Early years insulators are mostly used in poles, slowly developed in the high type of high-voltage power lines connected to one end of the tower hangs a lot of disk-shaped insulator, it is to increase the creepage distance, usually made of glass or ceramics, it is called insulators. Insulators should not fail due to a variety of electromechanical stresses caused by changes in the environment and electrical loading conditions, otherwise the insulator will not have a significant role, it will damage the use of the entire line and operational life.
Development history roots and overview: origin Tianheng power insulators are a special kind of insulating controls, can play an important role in overhead transmission lines. Early years insulators are mostly used for poles, slowly developed in the high type of high voltage power lines connected to one end of the tower hangs a lot of disk insulator, it is to increase the creepage distance, usually made of glass or ceramics, it is called insulators. Insulators in overhead transmission lines play two basic roles, namely, to support the wire and prevent the current back to ground, these two roles must be ensured.
