What are the structural specifications for high voltage harnesses?

I. The structure of the high-voltage wiring harness specification is how?1. line only structure: a qualified high-voltage wiring harness by the internal conductor, insulation, sheath, shielding, aluminum foil, wrapping tape, filler composition.2. High-voltage current system: power battery packs, motor controllers, air-conditioning compression motors, heater and defroster, power converter and so on, the rated voltage of 300V high-voltage DC power transmission system mainly consists of rectifier station, inverter station and DC power transmission The DC transmission system consists of a rectifier station, an inverter station and DC transmission lines, as well as a grounding electrode and a grounding electrode lead. In the high voltage system, the high voltage current can reach several hundred amperes instantaneously, which requires higher current carrying capacity of the high voltage wiring harness. High-voltage wire harness design, to be fully considered. 3. Protection level: because the erosion of water and dust can easily cause the insulation of the wire harness to degrade, resulting in high-voltage breakdown, leakage and other safety hazards, high-voltage wiring harnesses for the layout of the time to pay special attention to avoiding the layout of the place where there is water, if the layout of the floor below, you should increase the corresponding shelter. But even so, the design of high-voltage wiring harness protection level should be higher, to meet the national standard IP67 standard requirements.
