vertical break disconnectors

Product Description

VERTICAL BREAK DISCONNECTOR: DESIGNATION:VB VOLTAGE:*5 kv CURRENT: Up to ***0A The vertical break disconnector is of simple design of two post insulator and one operating rod insulator. The arm moves vertical position by the operating rod insulator for disconnecting the line. This design is mostly used in Indian Railways electrification / traction. The disconnector is suitable for mounting Horizontally or Vertically as per sub-station layout. CONSTRUCTIONAL FEATURES: BASE FRAME Base frame is made our of a fabricated steel structure to withstand all the external forces like wind load, short circuit force and seismic force etc., CONTACTS Reverse loop silver plated copper jaws results good electrical & thermal conductivity. Current transfer takes place through line contact of fixed contacts supported by stainless steel springs, which ensures low contact resistance. LINKAGES All transmission hinge points are provided with roller and socket type bearing with friction free nylon washers to prevent any slackness and consequent lost motion.
