Raw material selection
The raw materials used in the high-voltage wiring harness include high-voltage connectors, terminals, high-voltage wires, corrugated tubes, heat shrinkable tubes, shielding rings, conductive tapes, etc. Among them, there are many types of wire specifications, such as the same specifications due to voltage, temperature, bending There are large differences in factors such as radius, so the selection of suitable raw materials is crucial for product processing.
Wire selection
Commonly used automobile high-voltage wires use orange wires, and the corresponding specifications and conditions of use are printed on the outer insulation of the cables, as well as warning signs, such as “(Attention to high-voltage danger)”. According to the voltage level, it can be divided into AC600V/DC900, AC1000V/DC1500V; the temperature resistance level of common wires is 125℃, and different temperature resistance levels such as 150℃, 180℃, 200℃, etc. can also be selected according to the conditions of use; for the installation space In the restricted area, you can choose a wire with a smaller bending radius D, such as a silicone wire; according to the function, it can be divided into shielded and unshielded cables. For different connectors, single-core cables or multi-core cables can be used.
