12kV High Current Dry Type Composite Capacitive Wall Penetration Bushing

Product Introduction

This product is composed of main components such as the carrier, capacitor core, outer sheath, skirt, flange, and end structure. The flange features a measuring tap, which is used for partial discharge and dielectric loss factor measurements by opening it; it should be reliably grounded during normal operation. The carrier is a conductive busbar.
