3. Cross -sectional area

The cross -area of the wire is selected according to the size of the working current. For some electrical appliances with small currents, such as the indicator light circuit, in order to ensure the intensity of its due mechanical strength, the cross -sectional area of the wire must not be less than 0.5mm2. The cross -area of the wire is marked in front of the color code, and the unit is not marked when the unit is millimeter (MM). For example, 1.25R represents a red wire with a cross -sectional area of 1.25mm2; 1.0g/y means a two -color wire with a cross -sectional area of 1.0mm2. The main color is green and the auxiliary color is yellow.

The common specifications of the car wires in the car line are nominal cross -sectional area, with 0.5mm2, 0.75mm2, 1.0mm2, 1.5mm2, 2.0mm2, 2.5mm2, 4.0mm2, 6.0mm2 and other specifications. , A wires equipped with different power equipment. Take the entire vehicle beam as an example, the 0.5mm2 specification line is suitable for instrument lights, indicators, door lights, top lights, etc.; 0.75mm2 specification lines are suitable for license plate lights, front and rear lights, brake lights, etc Lights, fog lights, etc.; 1.5mm2 specification lines are suitable for headlights, speakers, etc.; Main electricity sources such as generator electrical hub lines, iron wires, etc. are required to use 2.5-4mm2 wires. This is just as far as ordinary cars are concerned, the key depends on the maximum current value of the load. For example, the iron wire of the battery and the positive power cord are used as a special car wire. Their wire diameter is relatively large, at least more than a dozen square meters, these "giant" wires will not be compiled into the main line.

Point

The common specifications of automotive wiring design are nominal cross -sectional area. Each of them has allowed load current values to meet the requirements of car electrical appliances with different power equipment equipment and reduce unnecessary power load.

The wire beam is a product reflection of the electrical schematic diagram. It is a carrier of the electrical system's power signal or data signal to transmit or exchange to achieve the function of electrical components and meet the real -time control of vehicle driving safety, reliable, and entertainment. As the percentage of electrical allocation in automotive research and development has continued to increase, the stability and safety of this carrier will be particularly important.
