Selection of Wire Harness Cross Sectional Area for Wire Harness Processing

The wire harness cross-sectional area of the wire harness processing should follow the principle of line cross-section selection and steps

Line cross section selection principle

(1) The conductors must be strong enough to avoid being pulled off by wind, icing, or repairs.

(2) When the load current is passed for a long time, the wire should not overheat to avoid damaging the insulation or causing fire on the circuit.

(3) voltage loss on the line can not be too large.

Select the cross-section of the wire

(1) When making low-voltage wiring harness, it is generally necessary to select the wire cross-sectional area according to the heating condition of the wire, and then check the voltage loss and mechanical strength conditions.

(2) When making high-voltage harnesses, the wire cross-sectional area is generally selected according to the economic current density, and then the test is conducted with the heating conditions and the voltage loss.
