Jinhua Dika Electrical Equipment Co., Ltd. proudly presents our Tear-Resistant EPDM Rubber 15kV Cold Shrink Single Core Cable Termination – a premium solution designed for reliable and long-lasting medium voltage cable connections. As a specialized manufacturer with over a decade of experience, we engineer this termination to deliver outstanding electrical performance, ease of installation, and exceptional resistance to environmental stress. The advanced cold shrink technology eliminates the need for heat or special tools, significantly reducing installation time and risk of human error. Our unique tear-resistant EPDM compound ensures the termination withstands mechanical abuse during installation and operation, providing a secure and durable seal for single core cables up to 15kV. Whether you are working on underground distribution networks, industrial substations, or renewable energy projects, this product offers the perfect balance of flexibility and ruggedness.
Product Features & Technical Advantages
- True Cold Shrink Design: Pre-expanded tube simply positions over cable jacket and shrinks upon removal of the support core – no heat, no flame, no special training required.
- Tear-Resistant EPDM Rubber: Special formulation resists cuts, punctures, and tears during installation and service life, maintaining dielectric integrity even in harsh environments.
- High Dielectric Strength: Designed for 15kV class systems with excellent partial discharge performance and consistent electrical stress control.
- Wide Operating Temperature Range: Proven performance from -40°C to +90°C, making it suitable for both arctic and tropical climates.
- Excellent Weather & UV Resistance: EPDM material offers superior resistance to ozone, sunlight, moisture, and chemical contaminants.
- Single Core Versatility: Compatible with a broad range of single core cables – XLPE, EPR, PVC insulated – with conductor sizes from 25mm² up to 400mm² (custom sizes available upon request).
- Integrated Stress Control: Built-in capacitive stress relief layer ensures uniform electric field distribution, eliminating corona and preventing insulation degradation.
- Simple & Safe Installation: No heat source, no flame, no resin mixing – reduces installation time by up to 50% compared to heat shrink alternatives.
