  • 252kV FRP Dry Porcelain Transformer Bushing

252kV FRP Dry Porcelain Transformer Bushing

The products of the company cover various voltage levels’ GIS bushing, transformer bushing, wall bushing, and current transformer. This series of products use PTFE and FRP composite as internal insulation and silicone rubber composite material as external insulation which has many advantages such as oil-free, gas-free, porcelain-free, explosion-proof, eco-friendly, maintenance-free and strong ability of anti-pollution flashover, etc,needless to say, they are the ideal substitutes of traditional oilpaper electric capacity type transformer bushings. Since the products was put into operation, they have won the praise of most customers and the recognition of authoritative experts by their advantages of stable operation, high reliability and maintenance-free, etc. and the company is making efforts to make power supply system develops into miniaturization, oil-free, and maintenance free.
