Product Name:

Cold Shrink Termination – Easy Installation, Reliable Sealing & Superior Electrical Performance

Description:

Cold Shrink Termination is a high-performance cable termination solution designed for medium and low voltage power distribution hubs, substations, and transmission tower connections. With advanced cold shrink technology, Cold Shrink Termination requires no heat source or special tools—simply pull out the inner core, and Cold Shrink Termination automatically shrinks to form a tight, permanent seal around the cable. Every Cold Shrink Termination is manufactured under strict quality control to ensure precision, durability, and long-term reliability.

Product Application:

• Medium and low voltage power distribution hubs

• Substation cable terminations

• Transmission tower feeder connections

• Outdoor cable terminations requiring high creepage distance and weather resistance

• Industrial power systems, utility networks

Features:

• Cold Shrink Termination features a 9-shed structure with maximum shed outer diameter of 150mm, ensuring sufficient creepage distance for outdoor applications;

• Large and small shed combination design provides excellent self-cleaning capability, preventing conductive paths between shed edges during heavy rain;

• Distortion-free expansion ensures inner wall remains smooth with no longitudinal grooves after installation, effectively eliminating potential creepage paths at the interface;

• Cold Shrink Termination requires no heat source or open flame, making installation safe, fast, and ideal for confined spaces;

• Cold Shrink Termination offers multiple size ranges to accommodate conductor cross-sections from 25mm² to 400mm² with precision fit;

• Cold Shrink Termination meets ROSH 2.0 standard, ensuring environmental compliance;

• Strict quality control with all fresh raw materials guarantees reliable performance;

• Cold Shrink Termination delivers ultimate peace of mind for cable terminations in demanding environments.

FAQ

Q1: What is the advantage of Cold Shrink Termination over heat shrink?
Cold Shrink Termination requires no heat source or flame, making it safer and easier to install, especially in confined spaces or hazardous environments. Cold Shrink Termination also eliminates the risk of uneven heating or improper shrinkage.

Q2: Why is the "no longitudinal groove" feature important?
Longitudinal grooves on the inner wall can create potential creepage paths after installation, compromising insulation performance. Cold Shrink Termination uses distortion-free expansion to ensure a smooth, uniform interface for reliable long-term operation.

Q3: How does the multi-shed design improve outdoor performance?
The combination of large and small sheds increases creepage distance, enhances self-cleaning, and prevents water bridging between sheds during heavy rain—critical for outdoor Cold Shrink Termination applications in polluted or wet conditions.

Q4: What cable sizes are compatible with Cold Shrink Termination?
Cold Shrink Termination offers multiple size ranges covering conductor cross-sections from 25mm² to 400mm². Please refer to the technical parameters table to select the correct range for your cable.

Q5: Is Cold Shrink Termination suitable for substation applications?
Yes. Cold Shrink Termination is specifically designed for medium and low voltage substations, transmission tower connections, and distribution hubs, meeting the demanding requirements of utility and industrial applications.

Q6: What is the maximum shed diameter of Cold Shrink Termination?
The largest shed diameter of Cold Shrink Termination is 150mm, which provides extended creepage distance while maintaining a compact profile suitable for most installation layouts.
