YJZGG-S 66-220kV Gas Immersed Termination

YJZGG-S 66-220kV Gas Immersed Termination
The 66kV-220kV GIS consists of a EPDM stress cone, an insulating material such as epoxy bushing and metals such as a compression unit and a protective tail tube. the surface pressure between the stress cone and the cable insulator is maintained by the compression device so as to guarantee its long-term behavior stable.
The main insulating elements shall be subjected to strict inspection after production in accordance with the relevant national standards and/or international standards. 
Characteristics of plug-in termination
The epoxy bushing shall be pre-installed in the GIS switchgear / transformer. Only insert the processed cable ends into the bushings without opening the compartment between the GIS switchgear / transformer at the construction site.
The insulating plugs shall match with the epoxy bushings. The tests such as the electrical performance of the GIS switchgear / transformers can be carried out in the factory to inspect and confirm so as to ensure the performance of the equipment.
The plug-in terminations of the SWCC SHOWA have been widely used as standards by major Japanese equipment manufacturers, which account for 90% of the Japanese market.
In recent years, this has gradually been accepted by the power equipment manufacturers in Taiwan China, Korea, Middle East, China, Russia and other countries and regions.
