What is Cold Shrink Termination?

In modern power systems, cable terminations belong to those ancillary elements that ensure safe energy transfer and distribution. With technological upgrading, one solution known as Cold Shrink Termination is steadily displacing conventional heat shrink technology and becoming the latest favorite in the industry. What then is Cold Shrink Termination? How does it operate? Where lie its special strengths? This article will discuss the technology and try to analyze its application across scenarios.

I. Basic Principles and Working Mechanisms of Cold Shrink Termination

Cold Shrink Termination is a cable terminal sealing technology based on pre-expanded elastomer materials. Its core principle is to use high-performance rubber (such as silicone rubber or EPDM) to pre-expand and fix it to the supporting core in the factory.

1. Combination of Materials Science and Shape Memory Technology

This tech depends on the stretch-memory features of the rubber stuff. With a special mix-linking way, it stays set even after growing until the help heart is taken out. This setup cuts off any need for heat while putting it in place lowering work risks by a lot..

2. Innovation of the Installation Process

Compared to traditional heat shrink technology, cold shrink installation requires only three steps: positioning the support core, peeling off the release layer, and allowing the shrink to occur naturally. The entire process can be completed in under five minutes, increasing efficiency by over 50%. This advantage is particularly evident when working in confined spaces.

II. Outdoor and Indoor Applications: The Difference Between Cold Shrink Outdoor Termination and Cold Shrink Indoor Termination

According to different application environments, Cold Shrink Termination can be divided into outdoor type and indoor type.

1. Technical Characteristics of Cold Shrink Outdoor Termination

The outdoor terminal features a multi-faceted protection design, including a composite shed structure that increases creepage distance to 1.5 times the standard value; a weather-resistant formula with UV and ozone inhibitors; and a fully sealed structure that achieves an IP68 waterproof rating. These features enable it to withstand extreme weather conditions and environmental pollution.

2. Design Advantages of Cold Shrink Indoor Termination

The indoor terminal features a compact design with a 30% smaller diameter to fit into narrow switchgear cabinet spaces. It also uses UL94 V-0 certified flame-retardant materials and has a shed-free design to prevent dust accumulation. These features make it an ideal choice for indoor power equipment.

III. Voltage Level Selection: Application Coverage from 1kv to 36kv

Cold Shrink Termination covers the complete spectrum from low voltage to medium voltage.

1. Application Scenarios of 1kV Cold Shrink Termination

Suitable for residential and commercial buildings, 1kV Cold Shrink Termination features minimal installation space, requiring only twice the cable's outer diameter. As an economical solution, it costs 25% less than heat-shrink cables. Its plug-and-play design allows for installation without the need for specialized tools.

2. Technological Breakthrough of 15kV Cold Shrink Termination

Innovations in the medium voltage field include a stress control system with a geometric stress cone design; a double sealing mechanism with built-in waterproof glue and an outer sealing layer; and applicability to a variety of wire cores, compatible with copper core, aluminum core and special-shaped conductors.

3. High-voltage Solution for 36kV Cold Shrink Termination

The high-voltage version features a special design with a voltage-equalizing shield made of semi-conductive material; the reinforced insulation thickness is three times that of the low-voltage version; and it has passed the IEC 60502-4 type test certification.

Ⅳ. Future Trends: Why Has Cold Shrink Termination Become the Mainstream of the Industry?

1. Technology Evolution Direction

The new generation of products is developing towards intelligence, with built-in sensors that can monitor temperature and humidity parameters in real time; the proportion of environmentally friendly materials used has increased to 30%; and the modular design supports on-site combination installation.

2. Market Drivers

According to industry data, improved installation efficiency has reduced overall costs by 40%; the failure rate has dropped by 60% compared to traditional technologies; and the market share is expected to reach 75% in 2025.
