BGB make center rotating type Triple Pole outdoor disconnecting switches are designed for higher Line current breaking capacity for line isolator as well as Bus Bar Isolators. The Isolators are having fixed and moving contacts made of HDHC Copper and die forged fingers of phosphorus bronze having inherent non deteriorating spring quality at high temperature and corrosion proof. The assembly of fixed and moving contacts is based on self compensating principle, to withstand both thermal and dynamic stresses of short circuit currents, and still carry the continuous rated current, with plenty of margin under ferrous parts are heavily tin plated to provide protection against corrosion, contacts for higher current rating are silver plated. Earthing switch can be installed on each pole at either end and interlocked mechaniclly with the main switch. The auxillary switches can be provided, Electrical motor drive mechanism complete with reduction gear and torque limiting safety features can also be provided. Isolators are manufactured in normal and solid core post insulator range fcom 6.6 KV to 220 KV approved by CPRI (Bangalore) in accordance to IS-1818/72 and IS 9921 (part|V) 1985.
