What is a SF6 Gas Insulated Metal Enclosed switchgear?
SR6.12/24/40.5 series of SF6 Gas Insulated Metal Enclosed Switchgear (C-GIS) is independently developed by our company with sulphur hexafluoride2as as the insulating, medium and can be applied in primary or secondary power distribution at a same time. itis a new-generation medium-voltage whole-set switcheear with vacuum arc extinguishing technology, APG solid sealed technology,gas insulation technology and interface insulation technology,.

Based on international advanced concepts, with world-class production, testing methods, laser welding, laser cutting and helium leak detectionequipment;
The primary components of the product are fully sealed in stainless-steel-plate-welded sealed gas tank,flled with SF6 gas at a certain pressure astheinsulating medium,and its protection grade is IP67 to prevent any influencefrom external environments and climate to the switchgearcabinet; itcan runreliably in basement, plateau, tundra, coastal, humid and other harsh environments without maintenance.
The product can be actuated manually or electrically, and the actuator is mature and reliable with complete mechanical and electrical interlocks toeffectively prevent personal injury and equipment damage due to any error in operation.
The product is compact, compared with traditional airinsulated switchgear, itis significantly smaller and the floor area occupied is less by 30%-70%o toimprove space utilization efficiency and effectively reduce comprehensive engineering cost.
The protection and system technology based on microprocessor combines protection,contro,metering,detection and communication functions to makethe power distribution network automatic and digital without personnel on duty.
The insulation is exceptionally robust.
Inside the cabinet, the structures used to support and isolate live metal components are made of high-strength fiberglass-reinforced plastic. Proven over decades, this material is both highly durable and insulating.
All copper busbars that transmit electricity are coated with a thick layer of epoxy resin insulation, akin to fitting the conductors with a sturdy "protective suit." This effectively prevents accidental electric shocks and short circuits.
Reasonable design of spring-actuated mechanism, fewer mechanical parts, balanced energy output and reliable
operation.With reliable mechanical and electrical interlocking devices, can prevent any error in operation.Automatic reclosing, the seal fixed plate is installed outside of the gas tank, it' s easy to disassemble and maintain,
without reliable seal of the gas tank.Interlocked with the circuit breaker to ensure that it can only close when the three-position switch is in the correctposition, with reliable performance.
The switch position is detected by sensor or auxiliary switch, with mechanical position indication.By manual double-hole operation, insulation hole and grounding hole are interlocked and the interlock solenoid ormechanical interlock hole can be prefabricated.
The built-in rectifier of mechanism actuator can be equipped with corresponding AC power supply or DC power supply.
The manual operation with limit device, only can remove handle when it arrives.
