View Product Description

220kV Dry Wall 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.
