72.5kV Fiber-impregnated Dry Type Capacitive Wall-through Porcelain Bushing

Product Introduction

This product consists of a carrier body, a capacitor core wrapped with resin-impregnated fibers, a porcelain jacket, a flange, and an end structure. Measurement terminals are fitted on the flange, which are used to open for partial discharge and dielectric loss factor measurements. It should be reliably grounded during normal operation. The product ends are equipped with device clamps.
