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. E 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.

Material –
Polyolefin based 11 – 33 KV jointing kits.
Application –
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.
