10/20/35kV Cold Shrink Cable Termination Kits & Joints

10/20/35kV cold shrink cable termination kits and joints are medium-voltage cable accessories designed for electrical insulation, stress control and moisture sealing in power cable systems. They are suitable for indoor and outdoor cable termination and jointing applications, with configurations available for different cable constructions and conductor sizes. Voltage range: 10kV, 20kV and 35kV.

What is a cold shrink cable termination kit?

A cold shrink cable termination kit is a pre-expanded elastomeric cable accessory that contracts around the prepared cable when its internal support core is removed. Unlike heat-shrink systems, installation does not require a gas torch or external heating equipment. Installation method: cold shrink, without heat application.

What voltage levels are available?

The series is designed for 10kV, 20kV and 35kV medium-voltage cable systems, covering common distribution and industrial power applications. The correct kit must be selected according to the cable voltage rating, insulation diameter and construction. Rated voltage classes: 10/20/35kV.

How does cold shrink technology provide stress control?

Cold shrink termination kits use stress-control components to manage the electric-field concentration around the end of the cable insulation and screen. This helps provide a controlled electrical transition between the cable insulation and the termination. Key function: electrical stress control at the cable screen cut.

Are cold shrink cable terminations waterproof?

Yes, cold shrink termination and joint systems use elastomeric sealing components to maintain radial pressure around the cable and help prevent moisture ingress. The sealing performance depends on correct cable preparation, component selection and installation. Key protection function: moisture and water sealing.

Are these kits suitable for XLPE cables?

Many medium-voltage cold shrink termination kits are designed for polymeric-insulated cables such as XLPE, but compatibility must be confirmed for each cable construction. Cable conductor size, insulation diameter, screen type and number of cores should be matched with the manufacturer’s product range. Typical insulation: XLPE.

What cable sizes can be used?

The applicable cable cross-section varies by voltage class and model, so the kit should not be selected by conductor size alone. A supplier should normally confirm both the conductor cross-section and the cable insulation diameter before shipment. Selection parameters: conductor size + insulation diameter.

Can the termination kits be used indoors and outdoors?

Yes, cold shrink cable termination systems can be supplied in configurations for both indoor and outdoor applications. Outdoor versions may incorporate additional environmental sealing and anti-tracking features depending on the design. Application types: indoor and outdoor termination.

What is the difference between a cold shrink termination and a cold shrink joint?

A cold shrink termination connects the end of a medium-voltage cable to equipment such as switchgear, transformers or other electrical apparatus. A cold shrink joint connects two cable sections and restores insulation, electrical stress control and sealing across the joint. Product types: termination + straight-through joint.

Why choose cold shrink cable accessories?

Cold shrink systems eliminate the need for flame or heating equipment, which can simplify installation where open flames are undesirable. The pre-expanded components also maintain continuous elastic pressure around the cable after installation. Installation requirement: no external heating source.

Where are 10/20/35kV cold shrink cable accessories used?

These products are used in medium-voltage power distribution and industrial electrical systems, including power supply networks, petrochemical plants, metallurgy facilities, railway infrastructure and seaports. The appropriate product should be selected according to the site’s voltage level and environmental requirements. Typical application voltage: up to 35kV.

What information is required to select a cold shrink termination kit?

Provide the system voltage, cable voltage rating, number of cores, conductor material, conductor cross-section, insulation diameter, cable screen structure and indoor/outdoor installation environment. These parameters allow the supplier to identify the correct termination or joint model. Minimum selection data: voltage + cable size + insulation diameter.

FAQ

What is a 35kV cold shrink cable termination kit?

A 35kV cold shrink cable termination kit is a medium-voltage accessory used to terminate a 35kV cable while providing insulation, electrical stress control and environmental sealing. Rated voltage: 35kV.

What is a cold shrink cable joint?

A cold shrink cable joint connects two sections of medium-voltage cable without using external heat during installation. It restores the cable’s insulation, stress-control and sealing functions. Product type: straight-through cable joint.

Is cold shrink better than heat shrink?

Cold shrink eliminates the need for a torch or other external heat source, making it useful where flame-free installation is preferred. The better option depends on the cable system, installation conditions, technical requirements and project specifications. Installation difference: no external heating for cold shrink.

Are cold shrink terminations waterproof?

Cold shrink cable accessories incorporate sealing components designed to limit moisture and water ingress. Actual waterproofing performance depends on the specific product design and correct installation. Protection function: moisture sealing.

Can cold shrink kits be used with XLPE cables?

Yes, many medium-voltage cold shrink systems are designed for XLPE-insulated cables. Always verify the cable’s insulation diameter and construction against the manufacturer’s compatibility range. Typical cable insulation: XLPE.

What voltage ratings are available?

This product series covers 10kV, 20kV and 35kV medium-voltage applications. The exact termination or joint model depends on the cable construction and dimensional range. Voltage range: 10–35kV.

What standards should I request from the supplier?

Ask for the applicable product standard, type-test report, routine-test information, technical datasheet and installation instructions. For medium-voltage cable accessories, the applicable standard may include IEC 60502-4, IEEE 48 or IEEE 404, depending on the product and application.

What information should I send when requesting a quotation?

For an accurate quotation, provide voltage rating, cable type, number of cores, conductor size, insulation diameter, cable screen type, indoor/outdoor application and required quantity. Providing these specifications reduces the risk of receiving an incorrectly sized termination kit.

Are these products suitable for power distribution projects?

Yes, 10/20/35kV cold shrink cable terminations and joints are designed for medium-voltage cable connection and distribution systems. They can be specified for industrial and infrastructure projects where the selected model matches the cable and electrical system. Application range: 10–35kV medium voltage.
