Our Catalogue

  1. Based on international advanced concepts, with world-class production,testing methods,laser welding,laser cutting and hellumleak detection equipment;
  2. The primary components of the product are fully sealed in stainless-steel-plate-welded sealed gas tank, filed with SF6 gas at acertain pressure as the insulating medium, and its protection grade is lP67 to prevent any influence from external environmentsand climate to the switchgear cabinet: it can run reliably in basement, plateau, tundra, coastal, humid and other harshenvironments without maintenance.
  3. The product can be actuated manually or electrically, and the actuator is mature and reliable with complete mechanical andelectrical interlocks to effectively prevent personal injury and equipment damage due to any error in operation.
  4. The product is compact, compared with traditional air-insulated switchgear, it is significantly smaller and the floor area occupiedis less by 30％-70% to improve space utilization efficiency and effectively reduce comprehensive engineering cost.The protection and system technology based on microprocessor combines protection, control, metering, detection andcommunication functions to make the power distribution network automatic and digital without personnel on duty.
