FLN36-12D,FLRN36-12D type indoor AC high-voltage sulfur hexafluoride load switch, load switch a fuse combination of electrical appliances and can be mounted cable head type load switch is my company digestion and absorption of foreign advanced technology. Combined with China's operational requirements, designed and developed by themselves, the product after a comprehensive type test, performance in line with GB3804 “3-63KV AC high-voltage load switch”, GB16926 “high any load switch-fuse combination of electrical appliances), IEC60265, IEC60420 standard requirements.
The product has a “one-point-one-grounding” three-station arc extinguishing chamber, reliable interlocking, high dielectric strength at the break, large creepage distance design, the outlet end is protected by an even-pressure protective cover, the cable head load switch is installed with a touch-type cable closure at the outlet end, and the inlet and outlet lines are equipped with high-voltage cables, which are equipped with the electric easy branching (connecting) box, and the switch is equipped with special dynamic sealing and fixed sealing designs. Special dynamic sealing and fixed sealing design. It is a new generation of high-voltage switchgear for urban power grids, with reliable sealing and a pressure gauge at the star position for monitoring during operation to ensure safety at a distance.
