The Role Of Intermediate Joints In Cold Shrink Cable Accessories

Cold Shrink Cable Accessories is typically made of a pre-expanded rubber body, which is released during installation to allow it to transition along the cable to the desired position, achieving a tight wrapping with the cable's outer sheath. These joint designs include inner and outer semi-conductive layers and conductor connecting tubes, which contribute to the continuity of the electric field distribution and the integrity of the overall structure.

The joint body is usually made of high-quality silicone rubber and is pre-formed in the factory to accommodate cables of different voltage levels. The internal semi-conductive layer and the metal shielding structure together form a closed space, ensuring a good interface between the composite structure and the cable insulation layer. During field installation, technicians do not need heating equipment; they simply slide the accessory along the cable and remove the core. The rubber material will then shrink back along the cable surface to conform to the external shape.
