Distribution line post insulators are used on the electrical poles and towers for supporting and insulating with insulator hardware fittings consisting of insulation body and end fittings.
The characteristics of Distribution line post insulators
◆ Good insulation performance
◆ Good mechanical strength
◆ Insulator surface is designed in wave form to increase creepage distance
◆ Good pollution performance
According to insulator material, Distribution line post insulators have
◆ Porcelain insulators: With good insulation performance, adapt to climate change in performance, thermal performance and flexible assembly, etc., it is widely used in various voltage levels of line
◆ Glass insulators: With tempered glass, with product small size, light weight, high electrical and mechanical strength, capacitance, good thermal stability, slow aging long life "zero value since the break," easy maintenance features
◆ Synthetic insulators: Travellers composite insulators, which is composed of three parts cob, umbrella plate and metal end caps consisting of iron.
Except Distribution line post insulators, distribution overhead line insulators include pin type insulator, post porcelain insulators, suspension porcelain insulators, shackle type insulator, porcelain crossarm insulators and railway porcelain insulators etc.
