The GN27-40.5 indoor high-voltage isolation switch is a new type of product. Suitable for opening and closing circuits in power systems with a rated voltage of 40.5kV and AC 50Hz, it is a replacement product designed and produced to replace old products under voltage and no load conditions. It can be paired with high-voltage switchgear or used separately. Equipped with CS6-2 operating mechanism. All adopt reinforced insulation design, which can meet the requirements for use in Class 1I polluted areas. Design scientifically, reasonably, and structurally novel; Multi contact, rotary contact, good self-cleaning ability, improving heat dissipation capacity; The contact point is within two surfaces, with low operating torque and high contact pressure, making it easy to adjust; Adopting a large creep distance to enhance insulation capacity and withstand voltage to meet the highest requirements; Installing bearings on the shaft increases its service life and makes it easy to operate. This series of isolation switches adopts a vertical rotating knife type three-phase common chassis structure. The static contact on the fracture side is designed as a swinging multi contact, which has the advantages of low contact pressure, low wear, large heat dissipation area, and small operating torque for a single contact. At the same time, it adopts large creepage post insulators and pull rod insulators, which have high insulation performance and mechanical strength. To meet the needs, there are designs such as flat mounted, wall mounted, and grounding knife equipped. This series of isolation switches can be installed horizontally, vertically.
