High Voltage Fixed Switchgear HXGN17-12/24/40.5KV

HXGN17 series box type fixed metal enclosed switchgear ,the main primary elements used in the equipment are all redesigning, compared with the currently used handcart switchgear and GG-1 (A) F type switchgear, it has higher insulation level and protection level, and the internal does not use any form of interphase and the relative clapboard and insulation gas, the secondary circuit does not use secondary plugs ; It is widely used in 7.2~40.5kV electric power distribution system, as acceptance and distribution of high voltage power equipment. This product meets the requirements of “five prevention”.The products meet IEC298 standards “3~40.5kV AC metal closed switch”, .The switchgear meet the requirements of standard IEC62271-200,IEC62271-100 etc.
