SF6 gas-insulated load-break switch

insulatedthree-phase

VITZROEM Gas Insulated Load Break Switch is a SF6 gas-insulated multi-circuit switch that is installed on ground or underground at 22.9kV-Y or 22kV-△ underground distribution line. It is an optimal product that uses SF6 gas as the insulating medium superior for its arc extinguishing capability and the operating mechanism is a single-operation method with 3-ground circuit for distinguishing the lines and branch lines. Product Features 1) Switch Body - It is a 3-phase integrated operating, single-tank type that consists of switch, auxiliaries based on the operation method, cabinet based on the operation method, cabinet based on the installation type and so on. - It is equipped with a ground switch for each circuit and it is designed so that the operating state of the ground switch can be easily checked outside. - The body cabinet is 3mm or bigger and the front part where the bushing is mounted is 5mm or bigger and both are manufactured using a stainless steel plate[KSD37053(Type&Mark),STS304L] that can endure the inner gas pressure. It is designed to have a stable structure with strong electrical and mechanical characteristics and durability. - Bolts are not used in order to prevent gas leak and it is completely enclosed by TIG welding. The insulating material used in the inner part is the bisphenol, epoxy resin with excellent resistance to electrical and mechanical characteristics and SF6gas.
