Rocker switches are used for sectionalising overhead lines.
Rocker switches are available in distribution voltages from 3,3kv , 6,6kv , 11kv , 22kv and 33kv.
These 3 Phase operated units, allow a linesman to open the switch by means of a telescopic link stick. Units can be opened on load up to 630A and bigger units at 1250A, the nominal voltages being 33kv.
Automated (GSM) operated units are available for private overhead lines that cannot be accessed by the linesman.
These devices are ideal for sectionalising large sections of overhead lines for the industry , mines and larger urban areas.
