H(L)6-12/24/40.5630/20 SF6 Standard specification
H(L)6-12/24/40.5 series SF6 fully insulated and fully enclosed compact ring network cabinet(hereinafter referred to as inflatable cabinet) is suitable for three-phase AC 50Hz, rated voltage 24kV power distribution system, It can be used as a load current, an overload current, and a short circuit. It can also break capacitive loads such as no-load transformers, fixed-line overhead lines, cable lines and capacitor banks, and generate power in the power system.
Distribution, control and protection.H(L)6-12/24/40.5 adopts a fully sealed structure, all of which are sealed in a gas chamber welded by a stainless steel plate with a protection rating of IP67.
It can adapt to humid and salty fog, such as flood, heavy pollution and other harsh environmental conditions, and operate safe and reliable multi-loop ring network switchgear. Widely used in industrial parks, streets, airports, Residential areas, prosperous commercial centers, etc., are ideal equipment for distribution network automation. Also used in: compact box-type substations, cable branch boxes, opening and closing, wind power stations, subways and tunnels.
H(L)6-12/24/40.5630/20 Use of environmental conditions
