As a specialized manufacturer of electrical equipment, Jinhua Dika Electrical Equipment Co., Ltd. proudly presents its advanced 8.7/15kV 3-Core Cold Shrink Termination. Engineered for demanding industrial and utility applications, this termination combines robust explosion-proof protection with superior salt fog resistance, ensuring reliable performance in hazardous and corrosive environments. Our commitment to quality, backed by a comprehensive management system including ISO 9001, translates into a product designed for longevity, safety, and minimal maintenance, offering a dependable solution for your medium-voltage cable system needs.
This termination is designed for the secure and permanent sealing of 3-core medium voltage power cables. The cold shrink technology eliminates the need for heat sources or torches during installation, significantly reducing application time and complexity while enhancing on-site safety. The core advantages of our product are built around its specialized design features and material integrity.
Key Features and Technical Advantages:
- Explosion-Proof Design: Constructed to contain any internal arc faults and prevent ignition of surrounding flammable atmospheres, making it suitable for installations in petrochemical plants, refineries, mining operations, and other classified hazardous locations.
- Superior Salt Fog Resistance: The housing and sealing materials are specifically formulated to withstand prolonged exposure to saline mist and coastal environments, preventing corrosion and insulation degradation, which is critical for offshore platforms, coastal substations, and marine applications.
- Cold Shrink Installation: The pre-expanded, rubber-based termination is simply positioned over the cable end. Removal of the core support layer allows it to shrink tightly onto the cable, forming a permanent, waterproof, and airtight seal without thermal stress on the cable or the need for skilled flame work.
- Excellent Dielectric and Mechanical Properties: Provides high resistance to tracking, UV radiation, and ozone, ensuring long-term insulation integrity. The robust design offers high resistance to impact, vibration, and mechanical stress.
- Wide Temperature Range Performance: Operates reliably across a broad ambient temperature range, maintaining flexibility in cold conditions and stability in high heat.

Frequently Asked Questions (FAQ):
Q1: What is the primary advantage of a cold shrink termination over a heat shrink one?
A: The main advantage is the elimination of an open flame or heat source during installation. This makes the process safer, faster, less skill-dependent, and suitable for environments where hot work permits are restrictive or hazardous.
Q2: For which specific environments is the "Salt Fog Resistant" feature most critical?
A: This feature is essential for installations in coastal areas, offshore platforms, marine vessels, and industrial plants near the sea where airborne salt can accelerate corrosion and degrade standard insulating materials.
Q3: Does the explosion-proof design require any special grounding or additional accessories?
A: The termination itself is designed as a contained system. However, proper grounding of the cable shield/screen according to the installation instructions and applicable electrical codes is always mandatory for safe and correct operation.
Q4: Can this termination be used on both copper and aluminum conductor cables?
A: Yes, typically cold shrink terminations are compatible with both copper and aluminum conductors. It is crucial to select the correct termination size based on the actual cable diameter and conductor size.
Q5: What is the expected service life of this product under normal operating conditions?
A: When installed correctly on a compatible cable and operated within its specified ratings, these terminations are designed for a long service life, often matching or exceeding the lifespan of the cable system itself, typically decades.
Q6: Are these terminations reusable or re-enterable after installation?
A: No, cold shrink terminations are designed as permanent, one-time installations. The rubber shrinks and forms a bond with the cable jacket, making re-entry without damaging the seal very difficult.
Q7: How do I ensure I order the correct size for my cable?
A: You will need to provide the precise outer diameter of your cable's insulation and the conductor size. We recommend consulting our technical datasheets or contacting our sales team with your cable specifications for accurate sizing.
Q8: What quality management systems support the manufacturing of this product?
A: Our production is governed by a robust quality management framework, which includes ISO 9001 among other industry-recognized standards, ensuring consistent product quality and performance.
