What are the Specifications of Low-voltage Wires for Making Automotive Wiring Harness?

As we all know, with the continuous improvement of people's living standards, almost every household has a car, and even some families have more than one car. There are many parts on the car, one of which is our product, that is the Wiring Harness. Our company produces high-end customized wiring harnesses. Since the company was established in 2015, we have produced various automotive wiring harnesses, so we have a wealth of experience. Today, let's talk about low-voltage wiring harness.
Common specifications of wires in automobile Cable Assembly include wires with nominal cross-sectional areas of 0.5, 0.75, 1.0, 1.5, 2.0, 2.5, 4.0, 6.0 and other square millimeters (the nominal cross-sectional areas commonly used in Japanese cars are 0.5, 0.85, 1.25, 2.0 , 2.5, 4.0, 6.0, etc. square millimeters), each of which has an allowable load current value, and is used for wires of different power electrical equipment. Taking the whole vehicle wiring harness as an example, the 0.5 specification line is suitable for instrument lights, indicator lights, door lights, dome lights, etc.; the 0.75 specification line is suitable for license plate lights, front and rear small lights, brake lights, etc.; Lights, etc.; 1.5 gauge wire is suitable for headlights, horns, etc.; main power lines such as generator armature wire, ground wire, etc. require 2.5 to 4 square millimeters of wire. This only refers to the general car, the key is to see the maximum current value of the load. For example, the ground wire of the battery and the positive power supply wire are special car wires used alone. Their wire diameters are relatively large, at least a dozen square millimeters. Above, these "Big Mac" wires will not be woven into the main harness.
Now, we have enough experience to produce Industrial Cable Assembly, Medical Cable Assembly and new energy Wire Harness. We will explore more areas in the future.
