Fast charging cable for new energy electric vehicle charging pile

Abstract

The invention relates to a fast charging cable for a new energy electric vehicle charging pile. The invention belongs to the technical field of wires and cables. The fast charging cable includes two main power line cores, a protective ground line core, a control cable core, a monitoring cable core, filling, an inner layer, a total shielding layer, and a sheath layer. The main power line core and the protective ground line core are formed by conductors, cladding layers and insulating layers. The control cable core is formed by conductors, an insulation layer, filling, a sub-shielding layer, and a cable core protective layer. The monitoring cable core is formed by conductors, an insulation layer, filling, a sub-shield layer, and a cable core sheath layer. An inner protective layer is arranged outside the main power line core, the protective ground line core, the control cable core and the monitoring cable core. A total shielding layer is arranged outside the inner protective layer. A sheath layer is extruded outside the total shielding layer. The fast charging cable has the advantages of high voltage level, good flexibility, good tensile resistance, excellent flame retardancy, weatherability, chemical resistance and electromagnetic interference resistance.

Description

technical field [0001] The invention belongs to the technical field of electric wires and cables, in particular to a fast charging cable for a new energy electric vehicle charging pile. Background technique [0002] At present, the smog weather is becoming more and more serious, the scope and duration of smog have increased, and a large amount of PM2.5 in the air has greatly affected the health of the people. Traffic is an important source of air pollution in many cities. In order to reduce the emission of pollution sources, the country vigorously promotes new energy electric vehicles. With the increasing number of new energy electric vehicles, the charging of new energy electric vehicles has become an important factor restricting its development. . [0003] The long charging time of new energy electric vehicles leads to low utilization rate of charging piles. The number of existing charging piles cannot meet the charging needs of new energy electric vehicles. In order to c...
