126kV 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. A measuring tap is provided on the current transformer housing, which is opened for use during partial discharge and dielectric loss factor measurement, and should be reliably grounded during normal operation. The product ends are equipped with equipment clamps.
