Description

Waterproof power cable Technical Field The utility model relates to the technical field of power cables, in particular to a waterproof power cable. Background The power cable is a kind of electric equipment specially used for transmitting and distributing electric energy, and is formed into a multilayer protection structure by conductor, insulating layer, shielding layer and protecting layer. The high-power high-voltage power supply has the core functions of efficiently conveying high-power electric energy in a power system, covering the full-voltage class from 1kV low voltage to 500kV and above ultrahigh voltage, and has the characteristics of high-voltage high-capacity transmission, complex environment adaptability and high safety. The system is mainly applied to the fields of urban underground power grids, industrial and mining enterprises power supply, power station outgoing lines, submarine power transmission, rail transit systems and new energy, and is a key infrastructure for replacing overhead lines, realizing hidden wiring and stably supplying power in severe environments. In the process of laying the power cable, the end parts are required to be connected, water is required to be prevented after connection, and the traditional water prevention treatment is to wind an insulating adhesive tape at the connection part, so that a gap is reserved on the winding adhesive tape easily if an operator is not skilled, and the water prevention effect is affected.
