72.5kV Dry Insulation Transformer Bushing
Product introduction:
Resin Impregnated Fiberfill bushing combines advantages of oil-paper bushing and RIP bushing. Advanced and imprvoed techniques make bushing better prevent from deformation, rupture and moisture absorption.
Advantage:
1/ Partial discharge is close to 0 at rated voltage;
2/ Dielectric dissipation ＜0.35% at rated voltage;
3/ Thermal short-time current: 25Ir, duration 2s.
