110kV Dry Type Composite Current Transformer

Product Introduction:

This product is composed of main components such as the carrier fluid, capacitor core, outer sheath, skirt, secondary winding, bottom housing, and terminal structure. The bottom housing features a measuring tap, which is opened for use during partial discharge and dielectric loss factor measurements. Under normal operation, it should be reliably grounded.
