Scope of application:

For cross linked polyethylene insulated power cables 240-3000mm2.

Suitable for large-scale chemical industry, iron and steel, power substations, coastal areas.

Features:

  • Dry insulated plug-in construction without any insulating filler..

  • Stress cone adopts imported liquid silicone rubber injection molding, by the spring and cone support Precise positioning, to ensure close contact with the cable, epoxy casing cone surface.

  • Compact structure, small volume, light weight, easy installation and maintenance.

  • The top fixture is pre-cast in an epoxy sleeve and the plug-in metal sealing structure ensures a Top sealing.
