Rubber Insulator Switch Silicone

Rubber/Porcelain Insulator Switch Silicone is an outdoor high voltage air insulating disconnecting switch, that is used in HV power networks for switching them on and off, and that provides support for a reliable and safe operation of networks. They are suitable for preserves with strict ecological regulations.

This disconnector is used to achieve a clearly visible disconnection of parts of power distribution networks, passing through a process of repairs, revisions, and other works that necessitate having the line in a non-live state.
