Cold shrink cable joints and terminations are advanced electrical components designed for connecting and terminating power cables. Unlike traditional heat-shrink methods, cold shrink technology relies on pre-expanded elastomeric materials (e.g., silicone or EPDM rubber) that contract **automatically at ambient temperature** after removing a removable plastic support core. This creates a tight, waterproof seal around the cable without requiring heat sources, making installation faster, safer, and more reliable.
No Heat Required: Eliminates fire risks and equipment damage caused by open flames or torches.
Pre-Expanded Design: Ensures uniform radial compression for consistent insulation and sealing.
Environmental Resistance: Resists moisture, UV radiation, chemicals, and extreme temperatures.
Flexibility: Adapts to irregular cable surfaces and withstands mechanical stress or vibrations.
Power Distribution Networks: Medium-voltage (MV) and high-voltage (HV) underground cables.
Renewable Energy: Connections in wind turbines, solar farms, and substations.
Industrial Facilities: Oil & gas plants, mining operations, and railways.
Urban Infrastructure: Underground cabling systems in cities.
Faster installation in confined spaces (e.g., trenches, ducts).
No risk of overheating cable insulation.
Long-term stability with no post-installation shrinkage.
Complies with international standards such as IEC 60502, IEEE 404, and ASTM D2671 for electrical performance, mechanical durability, and environmental testing.
Cold shrink joint: A sleeve-like device connecting two cable ends.
Cold shrink termination: Seals the end of a cable to a transformer, switchgear, or overhead line.
Stress control layer: Built-in component to manage electrical field distribution.
