Bending-resistant and rolling-resistant new energy automobile charging cable

Abstract

The invention discloses a bending-resistant and rolling-resistant new energy automobile charging cable, and relates to the technical field of cables. The bending-resistant and rolling-resistant new energy automobile charging cable comprises a cable body, which comprises a conductor, wherein the outer surface of the conductor is sleeved with an insulating layer, a communication line is installed onone side, close to the conductor, in the cable body, a PP net is filled between the conductor and the communication line, the outer sides of the conductor, the communication line and the PP net are wrapped with an isolation layer, and the outer side of the isolation layer is sleeved with a jacket. The preparation method comprises the following steps: wrapping the outer side of a cable body with an insulating layer, wrapping the outer sides of a conductor, a communication lines and a PP net with an isolating layer, wrapping the outer side of the isolating layer with a jacket to obtain the cable, and recovering the cable by using traction recovery equipment to obtain a product. According to the invention, the jacket of the cable is made of a special composite cross-linked TPE mixture, and aging resistance, flame retardance, weather resistance and oil resistance of the shell can be met at the same time, so that the service life of the shell can be prolonged, and the protection capacity for the internal structure of the cable can be enhanced.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a bending-resistant and rolling-resistant new energy vehicle charging cable. Background technique [0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as the power source, integrate advanced technologies in vehicle power control and drive, and form vehicles with advanced technical principles, new technologies, and new structures. When charging new energy, in order to To improve efficiency, a cable is often used as a charging medium. A cable is an electrical energy or signal transmission device, usually composed of several wires or groups of wires. [0003] A Chinese patent discloses a charging cable for electric vehicles and its preparation method (publication number; CN201510615225.2). Sheath; the inner core of the cable includes a power supply line, a grounding line, a signal transmission control line and an auxiliary power line; they respectivel...
