We manufacture 11kv-33kv gang operating switch , air break switch off load, disconnecting switch with triple pole. Each pole consist of galvanised steel base, H.T. insulators as per B.S.S./I.S, non ferrous knife and spring loaded contact, arcing horns of adequete section to break the magnetizing current of the transformer's horizontal/vertical G.I. pipe adequete lenght for phase seperation, adequete lenght of G.I. pipe for operation from ground level and operating handle complete in both OFF and ON position. All ferrous are hot dipped galvanized and non ferrous parts are heavily tinned to withstand extreme weather. Manufactured in accordance with I.S.S., this roduct us suitable for horizontal vertical mounting.

All mounting accessories are part of isolator. No extra hardware required for installation. Can be installed without special tools and tackles, in less time. Can be mounted on single pole resulting in reduction in cost and saving in space. Quick make and break manual operation. High contact life, can be used for On-load operation. Unique contact design to ensure proper contacts resulting in reduced power losses. Quality as per international standards.

These switches (Isolators) have been designed for heavy duty applications, where the products should withstand vibrations or should have an exceptionally long life and repeat accuracy. Sturdy electrical elements, incast pin as a fulcrum to facilitate a smooth transition of bell crank lever for precise motion transfer, a wide scale (individually marked) with a specially designed rack.
