High quality 30*50 Low Voltage DMC SMC Epoxy Resin Copper Bushing insulator SB Series for Switchgear
An insulator is a device that is installed between conductors of different potentials or between conductors and grounding components and can withstand voltage and mechanical stress. Insulators come in many varieties and shapes. Although there are great differences in the structure and shape of different types of insulators, they are composed of two major parts: insulation parts and connecting fittings.
Insulator is a kind of special insulation control, which can play an important role in overhead transmission lines. In the early years, insulators were mostly used for telephone poles, and slowly developed in the high voltage wire connection tower with a lot of disk-like insulators, which is to increase the creepage distance, usually made of glass or ceramic, called insulators.
