Power cable accessories by TE Connectivity enhance your underground, overhead and substation application
Reliable power supply is the backbone of the energy industry. If a single splice fails underground, it could lead to several hours of network downtime. A leaking termination may cause ground contamination. TE Raychem cold shrink power joints and terminations** have over 30 years of in-field service life** and are designed to suit a broad range of applications, cable and conductor types. Cold shrink terminations cover a wide range of voltage levels from 5 kV to 145 kV, ensuring adaptability for various power systems, and a minimal number of products can cover a broad range of applications. The silicone-rubber cold shrink offers high UV resistance, further enhancing its durability in diverse environments. There are different kinds of cold shrink tubing materials available, each suited for specific environments and applications, such as outdoor, exposed, or challenging conditions.
With a pre-expanded silicone rubber body, the TE Raychem CSJA splices are an all-in-one solution for a smooth installation experience and a compact design for use on 1/C shielded power cables (15-35 kV). These are available as kits, which include all necessary components for splicing and terminations. They are compatible with both mechanical and compression connectors, as well as aluminum connectors, leveraging the mechanical and electrical benefits of aluminum in cable accessories. Cold shrink technology is easy to install using a removable plastic core, simplifying the process for technicians. Cold shrink tubing exhibits active memory seal characteristics, allowing it to maintain adhesive capability during temperature fluctuations and accommodate thermal contraction and expansion, ensuring a secure seal even as cables move with temperature changes.
TE Raychem Cold Shrink Terminations CST are designed for polymeric cables up to 42 kV following CENELEC HD 629.1, and up to 35 kV accordingly to IEEE 404. They feature a hydrophobic silicone material that repels water and provides fire, high weathering, UV, and ozone resistance, making them suitable for indoor (CSTI) and outdoor (CSTO) applications. Cold shrink technology provides reliable sealing solutions for medium and high voltage applications, ensuring durability and performance. Liquid silicone rubber is used in pre-molded accessories to enhance mechanical and electrical properties.
Cold Shrink All-In-One Cable Splice
All-in-one solution engineered for smooth installation with tape shield, wire shield, LC shield, UniShield, JCN and flat strap shielded cables. Medium voltage cold shrink tubing cables provide a complete solution for various cable types and sizes, ensuring compatibility and efficiency. EPDM rubber used in cold shrink tubings is corrosion resistant, adding to the longevity and reliability of the solution.
CSTI Indoor Cold Shrink Terminations
Designed for indoor use, their components are pre-expanded on an easy-to-remove spiral holdout, allowing installation in compact environments. The installation process for cold shrink accessories involves simple steps and fewer critical techniques, making it user-friendly and efficient. The installation of cold shrink products is often simpler and requires fewer critical techniques compared to traditional methods.
CSTO Outdoor Cold Shrink Terminations
Designed for outdoor use, they offer a reliable, fast and easy-to-install system with high weathering, UV and ozone resistance. Cold shrink products are safer to install in environments with combustible gases due to the lack of direct heat, enhancing safety during installation. Additionally, cold shrink accessories do not require hot-work permits for installation, further improving safety and convenience.

Heat Shrink Applications for Versatile Protection
Heat shrink technology is a trusted solution for safeguarding cables and connectors in a wide variety of medium voltage applications. When used alongside cold shrink technology, heat shrink sleeves offer an additional layer of protection, sealing cables against moisture, dust, and other environmental contaminants. This ensures the long-term reliability of cable systems, even in challenging conditions.
Heat shrink is particularly effective for jacketed concentric neutral and longitudinally corrugated cables, providing a tight, secure fit that adapts to different cable forms and sizes. Its flexibility allows for use in a range of applications, from splicing to terminating cables, and it is suitable for creating strong, reliable bonds between cables and connectors. The installation process is straightforward, making it easy to use in the field and reducing downtime during projects.
By integrating heat shrink technology into your cable accessory systems, you can enhance the durability and performance of your network. Whether you need to protect a single cable or connect multiple conductors, heat shrink products deliver proven results, supporting the core technology needs of modern power distribution. Discover how heat shrink and cold shrink solutions together can create a comprehensive protection strategy for your next project.
Best Practices for Installation
Achieving optimal performance and safety from your cable accessories starts with following best practices during installation. Begin by selecting the appropriate cold shrink or heat shrink product for your specific application, considering factors such as voltage requirements, cable type, and environmental conditions. Get in touch with a Rexel Utility representative to ensure compatibility and to learn more about the features of each accessory.
Prepare the installation area by making sure it is clean, dry, and free from obstructions. Properly prepare the cable by stripping and cleaning the ends, ensuring a solid foundation for the accessory. Use the recommended tools and equipment for the product, and always follow the manufacturer’s instructions for installation. This includes correctly positioning the accessory, securing all connections, and verifying that the product is properly seated.
After installation, test and inspect the system to confirm that it meets all performance standards and application requirements. For additional support or guidance, contact Rexel Utility – we can provide expert advice and resources tailored to your project.
