66-220kV Dry-Type GIS Cable Termination

Introduction:
The 66-220kV Dry-Type GIS Cable Termination is designed with a purely dry structure. It features both plug-in and pluggable configurations for the cable core and epoxy sleeve, making installation and maintenance more convenient. The absence of any liquid or gas medium inside saves significant space.
