A 110 kV cold shrink cable dry-type terminal is a high-voltage cable termination solution designed for power transmission and distribution systems. It is widely used in substations, power plants, underground networks, and other installations where reliable insulation and long-term performance are required. Compared with traditional heat shrink terminations, a cold shrink type terminal does not require heating during installation. Instead, it uses pre-expanded elastomeric materials supported by an internal removable core. Once the core is pulled out, the terminal contracts automatically and tightly fits the cable surface, forming a secure and uniform seal.This type of terminal is mainly used for the ending of high-voltage XLPE insulated cables. Its primary function is to provide electrical insulation, stress control, environmental sealing, and mechanical protection at the cable end. Because the cable end is a critical point where electric field concentration can easily occur, the terminal structure is carefully designed to reduce partial discharge and prevent insulation failure. The dry-type design means that no liquid insulation or oil is used, making the product cleaner, safer, and easier to maintain.The 110 kV cold shrink cable dry-type terminal usually consists of several key layers and components, including a stress control tube, insulation body, sealing elements, and outer protective accessories. The stress control part helps manage the electric field at the end of the conductor shielding layer, which is essential for stable operation under high voltage. The insulation body provides the main dielectric strength, while the sealing system protects against moisture, dust, and pollution. The outer surface is generally made from weather-resistant and UV-resistant materials to ensure reliable outdoor performance.One of the major advantages of this terminal is its simple installation process. Since no open flame or special heating equipment is needed, the risk of installation error and cable damage is reduced. This is especially beneficial in confined spaces or hazardous environments. The cold shrink structure also offers consistent radial pressure, which helps maintain a tight interface between the terminal and the cable, improving electrical and mechanical reliability.In terms of performance, a 110 kV cold shrink cable dry-type terminal is designed to withstand high electrical stress, thermal cycling, and harsh environmental conditions. It can operate reliably in outdoor substations, coastal areas, industrial zones, and regions with severe temperature changes. Its compact structure, stable insulation performance, and maintenance-free characteristics make it an ideal choice for modern high-voltage power systems.Overall, the 110 kV cold shrink cable dry-type terminal is an advanced and practical solution for high-voltage cable termination. It combines safety, durability, easy installation, and strong electrical performance, making it an important component in ensuring the reliable operation of power networks.
