As a professional manufacturer with ISO9001 certified quality management, Jinhua Dika Electrical Equipment Co., Ltd. specializes in providing reliable and high-performance electrical solutions for global markets. Our High Voltage Heat Shrink Termination Kit for 35kV XLPE Underground Cable is engineered to deliver a secure, durable, and waterproof seal for critical power connections. This kit simplifies the termination process while ensuring long-term reliability in demanding environments, making it an essential component for power distribution networks, industrial facilities, and infrastructure projects.
The termination process for high-voltage underground cables is a critical step that determines the overall system's safety and longevity. Our kit addresses this need with a comprehensive set of components designed for ease of installation and superior performance.
- Advanced Heat Shrink Technology: The core of the kit utilizes specially formulated heat shrink tubes that contract uniformly when heated, forming a tight, seamless bond around the cable and connector. This process eliminates gaps and provides a consistent insulating layer.
- Integrated Sealing System: Pre-applied adhesives and sealants within the components activate during heating, creating a robust barrier against moisture, chemicals, and environmental contaminants. This is vital for underground or humid installations.
- High Dielectric Strength: All insulating materials are selected and tested to withstand the continuous electrical stress of 35kV operation, preventing breakdowns and ensuring operational safety.
- Corrosion and UV Resistance: The external layers of the termination are designed to resist corrosion from soil chemicals and provide protection against UV degradation for exposed sections.
- Flexibility and Strain Relief: The design accommodates cable movement and mechanical stress, reducing the risk of damage at the termination point from vibration or thermal cycling.
The kit includes all necessary components for a complete termination, ensuring you have everything needed for a successful installation.
| Component | Primary Function | Material / Note |
|---|---|---|
| Main Heat Shrink Tube | Provides primary insulation and environmental seal over the cable joint. | Cross-linked polyolefin with adhesive liner. |
| Stress Control Tube | Manages electrical stress at the termination interface to prevent discharge. | Semiconducting heat shrink material. |
| Connector / Lug | Electrical connection between cable conductor and equipment. | Tin-plated copper, size customizable. |
| Sealing Mastic Tape | Additional sealing for irregular surfaces or extra waterproofing. | Butyl rubber based, high adhesion. |
| Cleaning Solvent & Abrasive | Prepares cable surface for optimal adhesion. | Included in kit for preparation. |
| Installation Instructions | Step-by-step guide for proper installation. | Detailed manual provided. |
Key Technical Advantages and Client Benefits:
- Enhanced System Reliability: A properly installed heat shrink termination significantly reduces the failure rate of cable connections, minimizing downtime and maintenance costs for your power system.
- Simplified Installation: Compared to traditional tape-wrapping or cold shrink methods, the heat shrink process is faster, requires less skill, and yields more consistent results. This saves labor time and reduces installation errors.
- Long Service Life: The materials are resistant to aging, thermal cycling, and environmental factors, ensuring the termination performs reliably for decades, matching the lifespan of the XLPE cable itself.
- Safety Compliance: The design focuses on creating a safe interface with high dielectric integrity, reducing risks of electrical faults, fires, or accidents at the termination point.
- Adaptability: Kits can be tailored to specific cable diameters and conductor sizes. Contact us for customization options to fit your exact project requirements.

Frequently Asked Questions (FAQ)
Q1: What is the primary advantage of using a heat shrink termination kit over other methods?
A: Heat shrink kits provide a uniform, seamless seal with integrated adhesive. This method often offers better waterproofing, consistent insulation thickness, and faster installation compared to tape-wrapping or cold shrink alternatives, leading to higher long-term reliability.
Q2: Is special equipment required for the installation of this kit?
A: Yes, a heat source such as a propane torch or a specially designed heat shrink gun is typically needed to uniformly heat the tubes for proper shrinkage and adhesive activation. The kit includes instructions for the recommended tools.
Q3: Can this termination kit be used for cables above or below 35kV?
A: This specific kit is designed and tested for 35kV applications. Using it for higher voltages may not provide sufficient insulation, and for lower voltages it might be over-specified. We offer kits for different voltage ratings; please inquire for your specific voltage level.
Q4: How does the kit handle different cable sizes or conductor types?
A: Our standard kits are designed for common cable diameters. For non-standard sizes or specific conductor materials (like aluminum vs. copper), customization is available. Provide your cable specifications for a tailored kit solution.
Q5: What is the expected lifespan of a termination installed with this kit?
A: When installed correctly in a suitable environment, the termination is designed to have a service life comparable to the XLPE cable itself, often exceeding 30 years. The materials are selected for long-term resistance to environmental stress.
Q6: Does the kit provide protection against corrosion for underground use?
A: Yes. The heat shrink tubes and sealants create a barrier that protects the metal connector and cable from moisture and corrosive elements commonly found in soil, significantly enhancing corrosion resistance.
Q7: Are there specific environmental conditions (temperature, humidity) where installation should be avoided?
A: Installation should generally be performed in dry conditions. Extreme cold may affect the shrinkage behavior, and very high humidity can compromise surface preparation. The instructions provide guidelines for optimal installation conditions.
Q8: What quality assurance does the manufacturer provide?
A: Jinhua Dika Electrical Equipment operates under an ISO9001 Quality Management System. This ensures standardized processes, material checks, and batch testing to maintain product consistency and performance as per design specifications.
