When arranging high-voltage wire harnesses, it should be avoided that high-voltage wire harnesses are arranged alternately with fuel pipes and brake oil pipes. Even if they are arranged in parallel, the distance between high-voltage wire harnesses and oil pipes should be greater than 100mm.
Whether it is to avoid extrusion or to avoid areas with excessive vibration amplitude, when arranging high-voltage wire harnesses, it is necessary to pay attention to their bending radius. This is because the bending radius of the high-voltage wire harness has a great influence on the resistance of the high-voltage wire harness. If the high-voltage wire harness is excessively bent, the resistance of the bent part of the wire harness will increase, which will cause an increase in the line voltage drop.
The high-voltage wire harness has a large outer diameter and weight. In order to avoid stress concentration,
Under static load, the minimum inner bending radius of the high-voltage wire shall not be less than four times the outer diameter of the wire.
Under dynamic load, the minimum inner bending radius of the high-voltage wire should not be less than eight times the outer diameter of the wire.
Bending the wires in the connector needs to be avoided, otherwise a creepage path may develop in the rear seal of the connector.
The high-voltage wire harness that exits the tail of the high-voltage connector must be kept straight, and the high-voltage wires near the tail of the connector must not be bent or rotated.
