New energy DC cables are power cables used in DC power transmission and distribution systems. Except for their different electrical characteristics from AC, DC cables have basically the same structure as AC cables. Its main application is in new energy vehicles, electric vehicles, fast charging, and service areas. Comprehensive billing, security protection, and other functions.

DC power transmission and distribution systems typically operate on two wires (positive and negative), so DC cables are typically single core cables. Because the conductors of DC cables do not have skin effects and proximity effects, even if a large current is transmitted, it is not necessary to use a complex segmented conductor structure. The insulation of DC cables can be the same as that of oil impregnated paper insulated cables, solid extruded polymer cables, self contained oil filled cables, and gas filled cables. Since the armor layer is not affected by conductor current, it is not necessary to consider the loss of the armor layer and measures to reduce the resistivity of the armor layer.

High safety in use of DC cables: Due to the inherent characteristics of DC transmission, it is difficult to generate induced current and leakage current, and it will not generate electric field interference on other cables laid together. Single-core cable laying will not affect the cable transmission performance due to the hysteresis loss of the steel structure bridge. It has higher current interception ability and over wear protection ability than DC cables of the same structure. The DC and AC electric fields of the same voltage are applied to the insulation, and the DC electric field is much safer than the AC electric field. Compared to price, DC current is lower than AC cable, and installation and maintenance are simple.
