EHV Cable Indoor Termination
The gas insulated: termination is available for the connection of underground cables and GIS. This termination is widely classified into two types of configuration.
Prefabricated type termination: consists of an epoxy bushing, an EPR stress relief cone and a set of compression device to maintain the interfacial pressure between the stress relief cone and cable core.
Slip-on type termination: is equipped with silicone rubber stress relief cone. The interfacial pressure stability of slip-on type termination is achieved by self-elasticity of the stress relief cone.

The stress relief cone guarantees a sufficient positive pressure to control the electric field concentration under any service condition.
Plug-in type termination: has been developed under the technical concept of dry and prefabricated type. The plugin type termination can reduce the time and skill for installation. For protecting the epoxy insulator from switching impulse, the SVLs can be installed between cable sheath and GIS metal clad. Both fluid filled type and dry type are available. And blind ended interface has been developed and is available. We can also provide non-IEC type terminations complying with customer’s specification.
