First, outline

GW9, the HGW9-12 outdoors single pole isolator (hereafter refers to as switch) to be suitable for exchange frequency 50Hz, rated voltage 12kV and below, nominal current 630A and on the below distribution line, with puts through does not have the load with the isolation have Voltage single-phase or the three phase circuit. The HGW9-12 outdoors single pole high pressure isolator uses the silica gel synthesis insulator, the copper appendix, the stainless steel fastener and the foundation, has good antifouling and the anti-corrosive ability, also the weight light, the installment is convenient, does not need the periodicity to sweep clear with the maintenance, is the city and in the countryside 10kV distribution line makes the partition, the branch, the overhaul section supposes the obvious cut-off point the moderate price convenience outdoors high pressure electrical equipment. The HGW9-12 outdoors single pole high pressure isolator by the foundation, the insulator, the current carrying part, the insurance hook and so on partially is composed. On the tire is loaded with insures the hook, after Gathers Floodgate namely voluntarily Shuts Lock, cannot because of be self-possessed or the electromotive force function but the automatic minute floodgate. The isolator carries on with the insulation rod hook gathers a minute operation. The isolator designs the single-pole structure, carries on the single-phase analysis and synthesis in the three-phase line the distinction control. This product conforms to the GB1985-1989 standing operating procedure 。 Second, main technical parameter

Note: Catalogs nominal current 200-400A to have PorcelainWrap and the rubber wraps two kind of specifications, catalogs 600A is Porcelain Wrap,630A is the rubber wrap, when the ordering please give the explanation
