Embodiment Construction

[0023] see figure 1 with figure 2 As shown, the embodiments of the present invention will be described in detail.

[0024] Such as figure 1 As shown, the present invention relates to an electric vehicle charging pile cable. The charging pile cable is provided with a stranded wire core twisted into a bundle of 7 insulated wire cores 1, and the 7 insulated wire cores 1 are respectively two One main wire core, one ground wire core, two spare wire cores, one signal wire and one control wire, each of the insulated wire cores 1 includes a conductor 11 and an insulating layer 12 wrapped outside the conductor, the The signal line 1' and the control line 1" also include a phase-separated shielding layer 13, which is wrapped around the insulating layer 12; the outer layer of the stranded wire core is extruded with an inner sheath layer 2 , the total shielding layer 3 and the outer sheath layer 4.

[0025] The insulating layer 12 is a TPE insulating layer, the inner sheath layer 2 i...

Abstract

The invention provides a cable for an electric automobile conduction charging system, and a preparation process thereof. The cable for the charging system is internally provided with seven insulation cores which are twisted to form a beam of twisted cores, the seven insulation cores are respectively two main cores, one ground core, two backup cores, one signal line and one control line, each insulation core comprises one conductor and an insulation layer wrapping the conductor, the signal line and the control line each further comprises a phase-splitting shielding layer, and the phase-splitting shielding layers wrap the insulation layers; and the external layer of the twisted cores is successively extruded by an inner sheath layer, a total shielding layer and an oversheath layer. The product provided by the invention has the advantages of quite high mechanical tensile strength, wear resistance, corrosion resistance, interference immunity, flexibility, reciprocating bendability, low-transfer impedance, vehicle rolling resistance, high appearance roundness, low production cost and the like.

Description

【Technical field】 [0001] The invention relates to a preparation process of a cable for a conductive charging system of an electric vehicle. 【Background technique】 [0002] At present, with rising oil prices and increasingly severe pressure on energy conservation and emission reduction, new energy vehicles have become the development trend of the world's automobile industry, and electric vehicles have become the strategic industry direction determined by the governments of major automobile manufacturing countries in the world. my country has also listed new energy vehicles as a national strategic emerging industry, and introduced a series of incentives such as subsidies for government purchases of electric vehicles and plug-in hybrid vehicles. The rapid development of electric vehicles in my country has ushered in new development opportunities for related supporting industries. As an indispensable and important part of electric vehicles, cables for electric vehicle conductiv...
