The role of cable accessories in distribution transformers mainly includes insulation, sealing, protection, and connection. The cable accessories are made of special materials and designed to ensure that the conductors inside the cable are isolated from the external environment, preventing leakage and short circuit accidents. At the same time, the insulation oil inside the cable will not leak out, thereby extending the service life of the equipment. In addition, cable accessories also have mechanical protection function, made of materials such as metal or hard plastic, with strong tensile strength and compressive strength, which can effectively protect cables from external damage.
