Features of ceramic insulators



Disc insulators and pin insulators in ceramic insulators are mainly used for high and low voltage transmission lines, and suspension insulators are used for high voltage transmission lines. Ceramic insulators are a special insulation control that can play an important role in overhead transmission lines. In the early years, ceramic insulators were mostly used for utility poles, and gradually developed into a high-voltage wire connection tower with a lot of disc-shaped insulators hanging at one end. It is to increase the creepage distance. It is usually made of ceramics, which is called ceramic insulators. Ceramic insulators play two basic roles in overhead transmission lines, namely supporting wires and preventing current from returning to the ground. These two roles must be guaranteed. Ceramic insulators should not be damaged due to various electromechanical stresses caused by changes in environmental and electrical load conditions. Otherwise, the ceramic insulator will not play a significant role, and it will damage the service and operating life of the entire line.
