252kV Dry Type Composite Capacitive Wall Penetration Bushing

Product Introduction

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