The Important Role Of Insulators In Cable Terminations

suspension type insulator plays a role in managing the distribution of electric field stress in cable terminals. After the cable shield is removed at the terminal, the high electric field strength will change drastically at the junction of insulation and conductor. composite tension insulator improves the electric field distribution in this area through its geometric design and material dielectric properties, which helps to reduce the risk of partial discharge and dielectric damage.

In terms of mechanical support, the high voltage transmission line insulators connection cable ends are connected to the power distribution or transmission equipment, bearing the tension from the cable body and external loads, thus keeping the connection structure stable. Since cable terminals are often deployed outdoors or in areas with limited installation space, the mechanical design of overhead power line insulators must meet long-term tensile and vibration conditions.
