car wire harness, also known as low-voltage wire, it is not the same as ordinary household wires. Ordinary household wire is copper single core wire, a certain hardness. The car wires are copper multi-core cord, some soft lines like hair, a few or even dozens of soft copper wire wrapped in plastic insulated tube (PVC), soft and not easy to break.
Due to the particularity of the automotive industry, automobile wiring harness manufacturing process than other ordinary wiring harness is more special.car wire harness The following are the same as the "
car wire harness commonly used specifications with a nominal cross-sectional area of 0.5,0.75,1.0,1.5,2.0,2.5,4.0,6.0 square millimeter of the wire (Japanese cars commonly used in the nominal cross-sectional area of 0.5,0.85,1.25,2.0 , 2.5, 4.0, 6.0 and other square millimeters), each of which has a permissible load current value, and is used for wires of different power equipment. The specification line is suitable for the lamp, the indicator light, the door lamp, the dome light, etc .; The 0.75 specification line is suitable for the license plate lamp, the front and rear small lamps, the brake lights and so on; 1.0 The specification line is suitable for turning lights,car wire harness fog Lights, etc .; 1.5 specifications for headlights, speakers, etc .; main power lines such as generator armature line, ground wire and other requirements 2.5 to 4 square millimeters of wire. This is only refers to the general car, the key depends on the maximum load current value, such as battery grounding line, the cathode power cord is a dedicated car wire alone,car wire harness their diameter is relatively large, at least a dozen square millimeters Above, these "giant" wire will not be included in the main harness.
