Description
RIF Bushing
1.Product Introduction
The resin impregnated iber(RIF)dry type capacitive type transformer bushings adopts rubber immersed fiber capacitors,and the outer insulation is divided into two types:high-temperature vulcanized silicone rubber composite jacket and ceramic jacket.The bushing capacitor core adopts stress division buffer layer technology,greatly reducing internal stress,stabilizing product quality,and improving the product’s ability to withstand cold and hotimpacts and operating level;
The casing has high mechanical strength and can withstand tensile tests of 1250N inboth horizontal and vertical directions for 10 days each;
The casing is oil and gas free,simplifying the sealing structure of the casing,ensuring reliable sealing and excellent anti leakage performance;
2.Based on standards:IEC60137,GB/T4109;
3.Product features:non oil filled,non air filled,fireproof,explosion-proof,environmentally friendly,maintenance free,and strong pollution resistance;
4.Main technical parameters:
4.1 Environmental temperature:-40~+55ºC
4.2 Rated voltage:12kV~363kV
