Cold Shrink Cable Termination for 8.7/15kV 3-Core Systems, Explosion-Proof & Outdoor Rated
Product Spotlights
As a specialized manufacturer with over a decade of experience in electrical insulation solutions, Jinhua Dika Electrical Equipment Co., Ltd. proudly presents our high-performance Cold Shrink Cable Termination for 8.7/15kV 3-Core Systems. Engineered for reliability in demanding environments, this termination is a critical component for ensuring safe and continuous power delivery in medium-voltage networks. Our product combines the convenience of cold-shrink technology with robust, explosion-proof construction, making it an ideal choice for outdoor installations where safety and durability are non-negotiable. Backed by a commitment to stringent quality management systems, we deliver terminations that meet the exacting standards of global power infrastructure projects.
Product Features & Technical Advantages:
- Cold Shrink Installation: Eliminates the need for heat sources or torches, enabling faster, safer, and more consistent installations in any weather condition. The pre-expanded rubber sleeve contracts uniformly onto the cable upon removal of the core, forming a permanent, moisture-proof seal.
- Explosion-Proof & Outdoor Design: Constructed with high-grade, track-resistant silicone rubber, the housing provides excellent protection against environmental hazards. Its design prevents the ignition of surrounding flammable atmospheres, making it suitable for hazardous locations such as oil & gas facilities, chemical plants, and mining operations.
- Superior Dielectric Performance: The integrated stress control layer and seamless rubber construction ensure optimal electric field distribution, effectively preventing partial discharges and corona, which are critical for the longevity of 8.7/15kV systems.
- Excellent Environmental Sealing: Provides superior resistance to moisture, UV radiation, ozone, corrosion, and a wide range of chemicals. The waterproof design maintains integrity in direct burial, duct, or aerial outdoor applications.
- Wide Temperature Range: Engineered to perform reliably in extreme temperatures from -50°C to +90°C, ensuring stable operation in both frigid and hot climatic zones.
- Compatibility & Flexibility: Designed for use with copper or aluminum conductors in three-core cable configurations. The one-piece design simplifies inventory and reduces installation time compared to multi-component, tape-based systems.

Frequently Asked Questions (FAQ):
-
Q: What is the main advantage of cold shrink over heat shrink technology?
A: Cold shrink terminations do not require heat for installation. This eliminates the risk of uneven heating, cable insulation damage, and fire hazards, while also allowing installation in confined spaces or adverse weather conditions where using a torch is impractical or dangerous. -
Q: Is this termination suitable for direct burial applications?
A: Yes, when correctly installed following our guidelines, the termination achieves a high degree of environmental sealing (comparable to IP68), making it suitable for direct burial, provided the overall cable construction is rated for such use. -
Q: What cable types and sizes is this product compatible with?
A: It is designed for standard 3-core, shielded medium voltage power cables. Specific compatibility depends on the cable's outer diameter and conductor size. Please consult our technical datasheet or provide your cable specifications for a precise match. -
Q: How does the explosion-proof feature work?
A: The design ensures that any internal electrical fault is contained within the robust, flame-retardant silicone rubber housing. It prevents sparks, arcs, or excessive heat from escaping to ignite the surrounding atmosphere, a critical requirement in Zone 1 or Zone 2 hazardous areas. -
Q: What is the expected service life of this termination?
A: Under normal operating conditions within its specified temperature and voltage range, the termination is designed for a service life exceeding 30 years, thanks to the high-quality, weather-resistant silicone rubber material. -
Q: Do you provide installation instructions or support?
A: Yes, each unit comes with detailed, step-by-step pictorial instructions. Furthermore, our technical support team is available to provide guidance for complex installations or to answer any specific questions you may have. -
Q: Can this product be customized for specific project needs?
A: We offer customization options, including variations in cable entry sizes, specific color coding, or branding. Please contact our sales team with your requirements for a feasibility assessment and quotation. -
Q: What are the main international standards this product meets?
A> Our terminations are designed and tested to meet the performance requirements of key international standards such as IEC 60502-4 and IEEE 48 for cable accessories, ensuring global acceptance.
