Problems solved by technology

Since the charging pile cable is exposed to the outdoor environment for a long time, it requires a large load current, and the conductor is easy to heat up when the cable is energized. If it is not detected in time, it may cause a fire, and it is frequently dragged and moved during use, which is easily crushed by cars and exposed to sunlight. Corrosion by factors such as air oxidation, wet water environment and acid-base compounds

Abstract

The invention discloses an electric vehicle charging pile cable, and belongs to the power cable technical field; the electric vehicle charging pile cable comprises a feed temperature optical fiber, two main power lines, a ground line, two auxiliary power lines, a pair of charging connection confirm lines, and a pair of charging communication lines; the wire cores are twisted to form a cable, and gaps are filled with filling material; the cable is wrapped in sequence from inside-out by a wrapping tape, an inner sheath, a shield layer and an outer sheath. The electric vehicle charging pile cable is excellent in flexibility, highly flame retardant, wear resistant, high in weatherability and anti-UV property, can feed back temperature control of the cable and contact points, thus preventing fire hazard caused by overheating; a waterstop rope is water resistant, so cable water tree and creep deformation can be prevented, thus prolonging life of the charging pile cable.

Description

technical field [0001] The invention belongs to the technical field of power cables, in particular to an electric vehicle charging pile cable. Background technique [0002] With the development of the automobile industry, automobile exhaust emissions have become one of the main pollution sources in cities. The new energy electric vehicles that follow have been supported by various countries and localities due to their low energy consumption, low carbon emissions, and low noise. With the rapid development of the electric vehicle industry, the demand for electric vehicle charging pile cables has also doubled. Since the charging pile cable is exposed to the outdoor environment for a long time, it requires a large load current, and the conductor is easy to heat up when the cable is energized. If it is not detected in time, it may cause a fire, and it is frequently dragged and moved during use, which is easily crushed by cars and exposed to sunlight. , air oxidation, wet water e...
