A 35kV three-core cold shrink cable termination is a practical and reliable accessory used to complete the end treatment of medium-voltage power cables in overhead, indoor, or outdoor applications. It is designed to provide electrical insulation, environmental sealing, and mechanical protection for the cable core conductors after the outer sheath and insulation layers have been prepared. Compared with heat-shrink solutions, the cold shrink type offers easier installation, more consistent performance, and reduced dependence on heating tools, making it suitable for a wide range of field conditions.This type of termination is commonly used on three-core medium-voltage cables rated at 35kV. The product is typically made from pre-expanded elastomeric materials that contract naturally after the internal supporting core is removed. During installation, the termination body shrinks tightly around the prepared cable surface, creating uniform pressure and a secure fit. This tight sealing helps prevent moisture ingress, dust contamination, and tracking on the cable surface, which are important factors in maintaining long-term electrical reliability.A 35kV three-core cold shrink cable termination usually includes several key components, such as insulation tubes, stress control elements, sealing accessories, grounding parts, and protective outer layers. These parts work together to manage electrical field distribution at the cable end and reduce the risk of partial discharge or insulation failure. The stress control section is especially important in medium-voltage systems, as it helps smooth the electric field where the cable insulation has been stripped back. In addition, the sealing structure protects the termination from outdoor weather conditions such as rain, humidity, ultraviolet radiation, and temperature changes.Installation of the cold shrink termination is generally straightforward. After the cable is prepared according to standard procedures, the installer places the termination components in the correct position and removes the supporting spiral or core. The material then contracts automatically to form a close and stable seal. Because no torch or heating equipment is required, the installation process is safer and more efficient, especially in confined spaces or locations where open flame is not allowed. This also reduces the possibility of installation damage caused by overheating.The product is widely used in power transmission and distribution networks, substations, industrial plants, renewable energy systems, and infrastructure projects. It is suitable for both indoor and outdoor applications, depending on the specific design. With proper installation and maintenance, a 35kV three-core cold shrink cable termination can deliver excellent electrical performance, long service life, and dependable protection for critical power connections.Overall, this termination is an effective solution for medium-voltage cable systems requiring safe, durable, and easy-to-install end sealing. Its combination of insulation, stress control, and environmental protection makes it a valuable component in modern electrical engineering.
