Suspension insulators have been used widely all over the world for high voltage transmission and distribution overhead lines with the voltage ranging from 10KV to 1000KV. Suspension insulators can be divided into three kinds according to their applications: suspension insulator, tension insulator and deadend insulator.
Suspension insulators include common suspension insulator types and anti-pollution suspension insulator types, and both of them can be divided into polymer composite suspension insulators in silicone rubber and porcelain disc suspension insulators in ceramic. As follows:
Composite suspension & tension insulators in silicone rubber type:
10KV~36KV insulators for high voltage distribution line
66KV~500KV insulators for high voltage transmission line
15KV~69KV deadend insulators for high voltage lines
