Inner Cone Plug-in Termination(GIS Plug-in Termination) product introduction:
NKS POWER GIS termination adopts a combined structure of silicone rubber prefabricated stress cone and epoxy sleeve, which is compatible with polymer cables. The size of the stress cone can be adjusted according to different specifications of cables. The terminal connection is a dry structure, and there is no need to add any insulating pouring agent to prevent oil leakage during operation. The insertion part is a preformed silicone body with integrated stress control and a mechanical lug for easy installation. The plug can be easily separated and reinstalled to facilitate later maintenance. The product structure is designed reasonably and the sealing is reliable.
Product execution standards: IEC60502.4, GB/T12706.4
