Silicone rubber high voltage insulator

Silicone rubber high voltage insulators are used in transmission and distribution overhead lines, substations and stations to connect electric cables to the body of tower.

The types of Silicone rubber high voltage insulators
Composite suspension insulator, voltage upto 1000kV
◆ Composite line post insulator, voltage upto 132kV
◆ Composite crossarm insulator, voltage upto 110V
◆ Silicone rubber hollow bushing insulator, voltage upto 1250kV
◆ Composite station post insulators, voltage upto 1150kV

Comparing porcelain and glass insulators, leakage distance for silicone rubber high voltage insulators is important. Shed profile, there has been no significant difference in reported rates of external flashover failure.

Silicone rubber high voltage insulators are more resistant to power arcs with only superficial burning and/or ablation of the housing observed.
