In the high-voltage cable of new energy electric vehicle, a layer of insulation layer of conductor, referred to as core wire, is to twist multiple wire cores into one strand with the specified twist distance and twist direction, and wrap a layer of wrapping tape at the same time. The so-called core, which is called cable forming in China, is one of the important processes in the production of stranded multi-core cables. The process of combining several insulated cores or units into a cable core is called core stranding.



The so-called core wire stranding technology also requires certain requirements:

The principle of twist pitch is the same as that of bundle wire. Both twist directions are the same, and one-time bundle is combined into one core wire.

It is well known that the twisting direction and cabling direction should be right. The steel strip shall be wrapped with double-layer left gap, and the wrapping gap shall not be greater than 5% of the width of the steel strip, and the gap of the inner steel strip shall be covered by the middle part of the outer steel strip, and the width of the outer steel strip overlapping the inner steel strip shall not be less than 15% of the width of the steel strip.

Core wire arrangement: according to the customer's use requirements, the core wire can be yellow, red, blue, etc. if there are arrangement requirements, it must be operated according to the drawings.

Fillers, commonly used fillers are: tear rope, cotton rope, PP rope The filling can be twisted with the core wire at the same time.

Tape wrapping: a layer of isolation layer wrapped outside the strand in the way of wrapping at the same time of the strand. The overlap rate is generally greater than 20%. Commonly used tape wrapping: non-woven fabric, PP tape, aluminum foil Wait.

The new energy high-voltage cable is used to connect the charging port with the battery, the interior of the battery, the battery with the engine and other components, as well as the battery energy storage equipment. It is particularly important for product production safety. However, Omega cable is a leader in the industry in technology. Over the years, it has established a new energy R & D team and committed to the development of conduction products of new energy vehicles. Now it has made technological breakthroughs in high-voltage cables and charging lines of new energy vehicles.
