66~110kV Dry Plug-in type GIS terminal
Description
Product Features
The whole terminal is a dry structure, the inner is not filled with insulating oil, both environmental protection, and maintenance free.
The combination of spring, the stress cone surface close to the epoxy ring wall, can keep the interface pressure constant term.
Easy installation, no need to charge six sulfur fluoride gas.
The main insulation parts have been tested in the factory according to the standard.
