knowledge about Termination Kits & Accessories

Termination Kits & Accessories are typically used for installation and connections at cable terminations in power systems. These kits and accessories include various parts, such as Heat Shrinkable Terminal and Intermediate Joint and Cold Shrinkable Terminal and Intermediate Joint, to ensure the safety, reliability and integrity of cable termination connections. They are widely used in power transmission and distribution to help ensure good connections at cable terminations, improving system performance and reliability.

The difference between cold shrink accessories and heat shrink cable accessories

Cold shrink accessories and heat shrink cable accessories are both used in electrical installations, but they have different characteristics and applications:

Cold Shrinkable Terminal and Intermediate Joint:

Cold shrinkable cable accessories are the use of elastomers (commonly used liquid silicone rubber and solid silicone) in the factory injection vulcanization molding, and then expanded, lined with plastic spiral supports to form various cable accessories parts.

1. Cold shrink accessories are prefabricated rubber or silicone tubes that shrink onto a cable or connector when a supporting core is removed.

2. They do not require heat to shrink and are installed by simply unwrapping the core, allowing the tube to contract around the cable or connector.

3. Cold shrink accessories are often used in situations where using heat for shrinkage is impractical or poses a safety risk, such as in confined spaces or when working with sensitive materials.

4.Cold shrinkable cable accessories have the advantages of small size, easy operation, rapid, no special tools, stronger resistance to aging and tearing, wide application range and less product specifications.

Heat Shrinkable Terminal and Intermediate Joint:

Heat shrink cable accessories, commonly known as heat shrink cable head, are widely used in the middle connection and terminal of crosslinked cables or oil-immersed cables with voltage levels of 35KV and below.

1. Heat shrink cable accessories are made of a special polymer material that shrinks when heat is applied, typically using a heat gun or other heating device.

2. They require heat to activate the shrinking process and provide a tight, secure seal around cables and connectors.

3. Heat shrink cable accessories are commonly used in a wide range of applications to provide insulation, strain relief, and protection against environmental factors like moisture and corrosion.

4. Compared with the traditional cable accessories, it has the characteristics of small size, light weight, safety and reliability, easy installation and cheap price.

In summary

Cold shrink accessories offer a convenient, heat-free installation option suitable for certain environments, while heat shrink cable accessories provide a reliable and secure sealing solution that requires the application of heat for activation. The choice between the two types of accessories depends on the specific requirements of the installation and the preferences of the user.

Three major precautions for the installation and production of cable accessories to prevent them from being punctured:

1）Installation environment: Be sure to be carried out in clear weather and no dust. If moisture and dust enter the cable head, partial discharge may be caused, slowly leading to the breakdown of the cable head

2）Installation size: be sure to strictly follow the installation instructions provided by the additional manufacturer, especially the installation size of the terminal body.

Most of the after-sales service is semi-conductive lap position, there is not in place or different sizes,

3） Peeling strength: no matter which layer of the cable, the knife strength must be 2/3 of the layer
