72.5kV Dry Type Composite Wall-through Bushing with Current Transformer

Product Introduction

This product is composed of main components such as the carrier, capacitor core, outer sheath, skirt, secondary winding, current transformer, and terminal structure. The current transformer housing features measuring taps, which are opened for use during partial discharge and dielectric loss factor measurements. During normal operation, it should be reliably grounded. The ends of the product are equipped with equipment clamps.
