If the high-voltage wire harness does need to be fixed in the vibration area, the layout suggestions are as follows:
● The first fixed point is at most 100mm away from the wire exit;
● The fixing part used for the first fixing point must be installed directly on the wire or on the bushing (avoid being arranged on the bellows);
● The pressure exerted by the fixed point on the high-voltage wire must not affect the insulation resistance of the wire.
In order to better improve the electromagnetic compatibility of the vehicle, it is generally recommended to follow the following layout principles when designing the laying of high-voltage wiring harnesses:
● Interference sources and their connecting wire harnesses (generally high-voltage wire harnesses) are recommended to be kept away from easily interfered parts and their connecting wire harnesses (generally low-voltage wire harnesses, especially signal wires in low-voltage wire harnesses), and arranged separately as much as possible.
● When the length of high-voltage and low-voltage wiring harnesses arranged in parallel (route in the same direction) is greater than 200mm, the spacing between high-voltage and low-voltage wiring harnesses is recommended to be at least 100mm to prevent the magnetic field generated by high-voltage wiring harnesses from affecting easily disturbed components.
● When the high-voltage wire harness conducts high-voltage electricity, a strong magnetic field will be formed around it, so the layout distance between the load of the high-voltage circuit and the power supply should be as short as possible, and at the same time, the high-voltage wire harness should be arranged close to the metal sheet metal of the body to reduce the The loop area reduces the external radiation of the magnetic field.
