40.5kV Dry-type Composite Wall Penetration Bushing

Product Introduction

This product is composed of main components such as the carrier fluid, capacitor core, outer sheath, skirt, flange, and end structure. A measuring tap is installed on the flange, which is opened for use during partial discharge and dielectric loss factor measurements. It should be reliably grounded during normal operation. The ends of the product are equipped with equipment clamps.
