[0002] Medium voltage cross-linked cables are used for medium voltage power transmission. The conductors are mostly copper or aluminum, and the insulation layer is made of cross-linked polyethylene. The performance is improved through cross-linking reaction, which can effectively isolate the current. Some cables are equipped with shielding layers inside and outside, which are made of semi-conductive materials to optimize the electric field distribution. They are often filled with materials to enhance mechanical strength and aging resistance. Some have armor layers to prevent mechanical damage, and the outer sheath protects the cable from environmental erosion. The cable has excellent electrical performance, good heat resistance, high mechanical strength, and is not limited by the height difference when laying. It has a long life and is environmentally friendly. It is widely used in urban power grids, industrial power distribution, commercial buildings, transportation, energy and other fields; The medium voltage cross-linked cable joint connects two sections of medium voltage cross-linked cables to ensure stable power transmission. It is necessary to maintain good conductivity and mechanical strength of the conductor connection, and also to ensure insulation, sealing and uniform electric field. Its structure includes a conductor connection part, which uses crimping or welding to connect the conductors. The insulation part restores the insulation performance, and heat shrink, cold shrink or prefabricated insulation materials are often used; the shielding part reconstructs the internal and external shielding to optimize the electric field; the sealing part prevents moisture and impurities from invading. During production, it is necessary to strictly follow the process and complete the steps of cleaning, stripping, connection, insulation treatment, sealing, etc. After completion, it must be tested for insulation resistance and withstand voltage.
