- Product Introduction
The 1kV / 10kV / 35kV Indoor Cold-Shrink Cable Termination is a high-performance accessory designed for terminating low- to medium-voltage cable ends in indoor environments. Utilizing an advanced tool-free installation method, the termination automatically shrinks and seals around the cable by simply unwinding the internal support core. This eliminates the need for open flames or heat, creating a permanent, active moisture seal and robust dielectric barrier.
Engineered for modern distribution networks, Indoor Cold-Shrink Cable Termination combines streamlined field deployment with long-term operational reliability, making them ideal for integration inside compact switchgear, distribution panels, and motor control centers.

Cold shrink bushing Test lab
The Core Function of the 300kV High-Voltage Test Laboratory
The primary mission of the 300kV High-Voltage Test Laboratory is to execute rigorous insulation integrity and dielectric withstand testing. This ensures that high-voltage electrical equipment operates safely and dependably under critical overvoltage conditions, including simulated lightning strikes, switching surges, or system faults. The facility is fully equipped to perform Power Frequency Withstand, Lightning/Switching Impulse Voltage, Partial Discharge (PD), and DC Withstand testing.
A Comprehensive, Three-Dimensional Product Verification System By seamlessly integrating with our adjacent specialized testing divisions, this laboratory completes a powerful, multi-disciplinary evaluation matrix. Together, our five core testing zones-Routine Performance, Accelerated Aging, Electromagnetic Compatibility (EMC), Environmental Simulation, and High-Voltage Testing-form an elite product verification ecosystem. This comprehensive framework spans from low-voltage signals to high-power distribution, and from standard indoor operating parameters to extreme environmental and electromagnetic conditions.
Application scenarios
Indoor Cold-Shrink Cable Terminations
are critical components designed to interface power cables with electrical equipment in sheltered, indoor environments. Typically deployed within commercial and residential building distribution networks, as well as industrial control systems, these terminations leverage advanced cold-shrink technology.
By completely eliminating the need for specialized heating tools or open flames, the installation process is rendered significantly safer, simpler, and faster. Furthermore, their inherent elastomeric properties deliver exceptional dielectric insulation and robust mechanical stabilization, ensuring the long-term integrity and reliability of the cable connections.
Installation Guidelines
| Installation Guidelines | Description |
|---|---|
| Cable Accessory Vulnerability | Cable accessories are the weakest link in a cable system; installation quality is critical to operational safety. |
| Qualified Installation Personnel | Must be installed by specially trained and certified cable accessory installation technicians. |
| Instruction Manual Compliance | Read the product instruction manual carefully and strictly follow the specified installation procedures. |
| Power Isolation & De-energization | Ensure all connected equipment and cables are fully de-energized and isolated before commencing installation. |
| Cable Condition Inspection | Verify the cable structure is intact and free of moisture ingress; do not install damp or moisture-contaminated cables. |
| Specification Matching Check | Confirm the cable accessory specifications fully match the cable parameters; inspect the packaging and integrity of all components. |
| Installation Weather Requirements | Avoid installation in rainy, foggy, or windy weather; implement pre-heating measures if the ambient temperature is below 5°C. |
| Cleanliness During Installation | Keep hands, tools, and materials clean at all times; prohibit unrelated activities (e.g., smoking) during the installation process. |
| Normal Installation Phenomenon | After heating, red sealant may extrude from the base of the cold-shrink sleeve; this is a normal occurrence. |
