Product Description
Product introduction
The product for the single-phase windings, relative to outdoor SF6-voltage transformer for 220 kV effective neutral grounding power system voltage, power measurement and protective relays.
Main features: compact, small size, light weight, mechanical shock resistance, anti-seismic, and a hot dip galvanizing the base, no corrosion, the main use of SF6 gas insulated, the insulation properties of stability, safe and reliable operation of non-oil products, No fire hazard, do not pollute the environment, with explosion-proof function. Easy maintenance, repair and intermediate without trial, online detection SF6 gas density. Core products imported materials used laser irradiation processing of high quality Magnetic orientation of silicon steel, product performance has greatly improved. Coil insulation performance by the excellent point polyester plastic film, the solution after formation of a solid overall performance and reliable .
