Heat Shrink Joints For MV Cables Up To 42kV For MV Screened For 1.Electrical Stress Control

The joints are designed for MV screened, 1 -core polymeric insulated cables with or without armour. The

same design principles are used for 3-core cables.
1. Electrical stress control

Stress control tube, together with stress relief mastic, is used to smooth out the electrical field at the cable screen ends.

2. Insulation and screen

Heat shrink insulation tube delivers consistent insulation thickness to meet or exceed that of the cable.

Heat shrink semi-conductive /insulation dual layer tube is also adopted to help ensure a void-free interface between the insulation and screen.

3 . Metallic shielding

Copper mesh wrapped around the joint area rebuilds the metallic screen. Either soldering or solderless earth connection is available to provide

screen continuity across the joint.

4 . Outer sealing and protection

The outer sealing and protection is performed by an adhesive coated, heat shrink tube. It provides mechanical protection and chemical resistance

as expected from cable oversheath.

Straight joint for screened, 1 -core polymeric insulated cables 6kV, 10kV, 20kV, 30kV and 35kV and 42KV

The joint is designed for screened single core polymeric insulated MV cables up to 42kV.

Stress control tube, together with stress relief mastic, is used to smooth out the electrical field at the cable screen ends. Heat shrink insulation

tube delivers consistent insulation thickness over the core insulation. Heat shrink dual layer tube is adopted to help ensure a void-free interface

between the insulation and screen. Copper mesh wrapped around the joint area rebuilds the metallic screen. Either soldering or solderless earth

connection is available to provide screen continuity across the joint. The outer sealing and protection is performed by an adhesive coated heat

shrink tube.

Note:
1 .Connectors need to be ordered separately.
2.RSJY-1 is for cables with copper wire screen without armour.
3.Solderless earth connection have to be ordered separately as follows:
•For cables with copper wire screen and wire armour, add suffix -WA. For example, 6kVRSJY-1/1 -WA.
•For cables with copper tape screen with armour wire,add suffix -X. For example, 6kVRSJY-1/1 -X.
