The laying of power cables has brought great convenience to our production and life. In addition to the main power cable, its accessories are also very important when laying the power cable. Power cable accessories generally refer to products that connect cables to transmission and distribution lines and related power distribution devices, and are responsible for the intermediate connection and terminal connection of various cables in the cable line. Common power cable accessories include cold shrinkable terminal head, cold shrinkable intermediate joint, cold shrinkable cable joint, inner cone plug-in terminal, American T-shaped head, European T-shaped head, heat shrinkable terminal head, heat shrinkable cable joint, etc. 

Cold-shrinkable terminal head is the general name of cold-shrinkable indoor cable terminal, cold-shrinkable outdoor cable terminal, cold-shrinkable intermediate joint and cold-shrinkable cable joint. The cold shrinkable terminal head is prefabricated by integral injection of imported liquid silicone rubber. Silicone rubber has excellent insulation and high elasticity. After installation, it always maintains a suitable radial pressure on the cable body, so that the inner interface is tightly combined. The stress control part adopts a stress cone structure and is prefabricated with the main insulation, which effectively solves the problem. The problem of cable stress concentration ensures reliable insulation and safe operation. Similarly, the heat shrinkable terminal is a general term for the heat shrinkable indoor cable terminal, the heat shrinkable outdoor cable terminal, the heat shrinkable intermediate joint, and the heat shrinkable cable joint. Heat-shrinkable cable terminals and intermediate joints are widely used on cross-linked cables or oil-immersed cables with voltage levels of 35kV and below. Compared with traditional cable accessories, heat-shrinkable cable terminals and intermediate joints have the characteristics of small size, light weight, safety and reliability, and convenient installation, and meet national standards. The long-term use temperature range is -55℃～105℃, and the aging life is long. 20 years, the radial shrinkage rate is ≥50%, the longitudinal shrinkage rate is less than 5%, and the shrinkage temperature is 110℃～140℃. The material used for the heat shrinkage stress control tube has a volume resistivity and a dielectric constant that match the electric field of the cable at the connection. During operation, a certain characteristic impedance is formed at the end of the cable shielding, which plays the role of electrical stress evacuation, thus ensuring the heat shrinkable cable accessories. Operational reliability and extended service life.
