Composite insulator FXBW4-66/70

Insulator is a special insulation control that plays an important role in overhead transmission lines. In the early years, insulators were mostly used on telephone poles
It gradually developed into high-voltage wire connection towers. Many disc-shaped insulators were hung on one end of the tower to increase the creepage distance, usually made of glass or ceramics
It's called an insulator. Insulators play two basic roles in overhead transmission lines, namely supporting conductors and preventing current from returning to ground. Insulators should not fail due to various electromechanical stresses caused by changes in environmental and electrical load conditions. Otherwise, the insulator will not play a significant role and will damage the use and operating life of the entire line.
