Post insulators Overview

Electrical equipment is an important pillar insulator knife substation equipment operation, plays a supporting role of conductor and insulation. Post insulators prevent accidents over the years fracture focus of our plant, to avoid post insulator grid fault accident also put forward higher requirements, power grid failures caused due to rupture of post insulators have occurred, affecting a wide, big loss, I plant several incidents have occurred in post insulator knife rupture accident, pose a great threat to the safe operation of the main pillars of the fracture due to mechanical weakening of the roots of aging insulators, post insulators after knife fracture caused partial damage accident. Post insulators ultrasonic testing technology in recent years the development of new technology, the introduction of this technology early detection of post insulators local damage, to prevent the operation of the post insulators sudden rupture of great significance, is a viable post insulators will fracture elimination of accidents methods.
