• Safe & Reliable: No heat required for shrinkage.
• Safe & Stable: The cold‑shrink intermediate joint adopts geometric stress cones at both ends plus a central Faraday Cage design. The cold‑shrink body maintains constant compressive force against the cable, ensuring safe and stable long‑term operation.
• Time‑saving & Labor‑saving: Simply pull out the inner support core, and the elastic body shrinks rapidly onto the installation position, minimizing installation‑induced defects.
• Material Properties: LSR material delivers excellent dirt resistance, anti‑aging performance, hydrophobicity, hydrophobic‑migration resistance and weather resistance.
• Wide Application Range: Suitable for high‑altitude, cold, humid, salt‑spray and heavily polluted areas. Outer protection options are available according to service and installation requirements: heat‑shrink tubes, cast resin, armour wrapping tapes, EPDM protective sleeves, etc.
• Compact Size: Short‑structure cold‑shrink intermediate joint effectively reduces cable stripping length.

0.6/1.0kV 4‑Core Cold‑Shrink Cable Intermediate Joint Installation — Multi‑core (Armoured / Non‑armoured)

Step 1: Cable Pre‑treatment

Move the cable ends to be installed into proper position. Straighten the cable within 2 m of the joint. Strip off the outer sheath, steel armour, inner lining and insulation according to the dimensions shown in the drawing. Roughen the surface over a 150 mm section at both ends of the outer sheath. Keep the cable inner filler intact. Slide the cold‑shrink tube onto the conductor insulation of end A, pay attention to the end orientation (see drawing). (For 4‑core cables, fit the thinner neutral‑core insulating tube over the thinner neutral‑wire insulation.)

Step 2: Cable Pre‑treatment

Crimp the connector tube in accordance with standard requirements. Remove sharp edges and burrs, grind to a smooth finish and clean the surface. Apply mastic filler to fill the crimp indentations as well as the gaps between connector tube and phase insulation, with an overlap of no less than 10 mm onto the phase‑insulation. Pull the cold‑shrink tube from end A and position it centred over the connector tube. Extract the plastic support strip to allow natural cold‑shrinking, ensuring overlap onto the left and right‑hand phase‑insulation.

Installation Difference: For steel‑armoured cables, secure the grounding wire from end A to end B with constant‑force springs before fitting the armour wrapping tape.
