SF6 Lasttrennschalter

General introduction: 1) FLN36-12 SF6 load break switch is a M.V. switch equipment produced and developed by our company. It is the main switch apparatus in the ring main unit 2) FLN36-12 SF6 three-station position load switch is a multifunction M.V. apparatus integrating switching-on, switching-out, and grounding into one. To ensure this product's quality, we put 0.05MPa SF6 gas into an ethoxyline crust with completely airproof and strengthen structure, so it has achieved the three functions above with the least apparatus and high reliability 3) Free from maintenance, it can safely operate upwards of 20 years in normal conditions Characteristics: 1) Safely running time is above 5 years in China 2) Integrated mechanical switch for switching, disconnecting and earthing switch encapsulated into ethoxyline-resin crust of full SF6 gas. Three positions are interlocking each other. Compact structure, safety and high reliability 3) Excellent technical performance, long electrical life, free of maintenance 4) Small volume, light weight, simple and convenient maintenance, convenient and safe operation Major technical parameters: 1) Rated voltage: 12kV 2) Rated current: 630A 3) Rated frequency: 50Hz 4) 1min P.F. withstand voltage (between phases, to earth): 42kV (across isolation distance): 48kV 5) Rated lightning impulse withstand voltage (between phases, to earth) 75kV (across the isolation distance: 85kV 6) Rated active load breaking current: 630A 7) Rated short-circuit making current: 50kA 8) Rated thermally stable current (3s): 20kA 9) Dimensions: 420 x 730 x 345mm
