Chemical-resistant functional cable for new energy electric vehicle charging system

Abstract

The invention discloses a chemical-resistant functional cable for a new energy electric vehicle charging system. A main body structure of the cable comprises three main power lines, two auxiliary power lines, a pair of shied charging communication lines, a pair of shied charging connection confirm lines and a standby control signal line, wherein a twisting gap of the main body structure is filled with an external filler; the outer side of the main body structure is sequentially coated with an outer tape layer, an outer strengthened shielding layer, an inner sheath, a metal layer and an outer sheath from the inside to the outside; and the metal layer is formed by longitudinal wrapping and welding and continuously spiral embossing of an aluminum tape. The cable can have the characteristics of good oil-resistant and chemical-resistant functions and excellent mechanical and physical electrical properties, and is soft, flexible, weather-resistant, high-and low-temperature resistant, ultraviolet-resistant, oxidation-resistant, anti-electromagnetic interference, stable in signal transmission, long in service lifetime and the like.

Description

technical field [0001] The invention relates to the field of wires and cables, in particular to a chemical-resistant functional cable for a new energy electric vehicle charging system. Background technique [0002] Compared with traditional vehicles, new energy electric vehicles have the characteristics of stable operation, no noise, no pollution, low carbon emissions, high safety, etc., and have broad market application prospects. ", with the large-scale promotion and industrial application of new energy electric vehicles, the demand for cables for electric vehicle conductive charging systems has also doubled. Due to the large load current value of the cable used in the conductive charging system of electric vehicles (up to 400A), but in the use of some workplaces that are exposed to oil, corrosive gases, aromatic solvents and chemicals, the cable sheath material is For general organic materials, the cable sheath will experience aging phenomena such as swelling, hardening,...

AI Technical Summary

Problems solved by technology

Due to the large load current value of the cable used in the conductive charging system of electric vehicles (up to 400A), but in the use of some workplaces that are exposed to oil, corrosive gases, aromatic solvents and chemicals, the cable sheath material is For general organic materials, the cable sheath will experience aging phenomena such as swelling, hardening, cracking, and dissolution. The insulation and sheath of the cable will age in a short period of time, resulting in damage to the cable and a low service life of the cable. This invisibly brings the operating cost and economic loss of the cable to the user. Therefore, it is necessary to put forward higher requirements for the chemical resistance of the outer sheath of the cable for conductive charging.
