Abstract

The invention relates to a cable for an electric automobile alternating current charging system and a manufacturing method of the cable. The cable comprises a cable core, the cable core is formed by twisting a three-phase power wire core, a grounded wire core, an auxiliary wire core and a signal transmission unit, the single three-phase power wire core structurally comprises a three-phase wire core conductor, and the periphery of the three-phase wire core conductor is wrapped by a three-phase wire core insulation layer through a three-phase wire core isolation layer. The grounded wire core and the auxiliary wire core are of the structure the same as the three-phase power wire core. The signal transmission unit structurally comprises a signal control wire core conductor, and the periphery of the signal control wire core conductor is wrapped by a signal control insulation layer, wrapping tape, a signal control unit shielding layer and a wrapping layer. A gap in the middle of the twisted cable core is filled with a hemp rope, and the periphery of the cable core is wrapped by a reinforced non-woven fabric belt, an inner protective layer, a shielding layer and an outer protective layer in sequence. The cable is compact and reasonable in structure, convenient to manufacture, excellent in performance, low in cost, strong in function and good in use reliability.

Description

technical field [0001] The invention relates to a cable, in particular to a cable for an electric vehicle AC charging system and a manufacturing method thereof. Background technique [0002] The State Grid Corporation stated that the State Grid has basically determined three areas of mixed ownership reform, namely DC UHV, electric vehicle charging and swapping facilities, and pumped storage power stations, and is currently formulating specific plans. [0003] Electric vehicles have always been regarded as the development trend of the next generation of vehicles. In the three major cities of Beijing, Shanghai and Guangzhou, due to traffic congestion, restrictions on car purchases have been imposed through license plates. However, due to the environmental protection effect of electric vehicles, the government supports electric vehicles from above. Therefore, major cities such as Beijing, Shanghai and Guangzhou have relevant policies. Electric vehicles that enter their relevan...
