Details of the types and advantages and disadvantages of electronic wiring harness assembly wires

Jan 17,2024

Electronic wiring harness is an important component in electronic products, composed of multiple wires, terminals, sheaths, etc., used for transmitting current or signals. Assembly wire is an important component of electronic wiring harnesses, which can be divided into copper core wire, aluminum core wire, enameled wire, shielded wire, flat wire, etc. according to different materials.
Copper core wire is the most commonly used assembly wire in electronic harnesses, with advantages such as high conductivity, good corrosion resistance, and easy bending. But the price of copper core wire is relatively high, and it is easy to oxidize in high temperature environments.
Aluminum core wire has a higher conductivity than copper core wire, but it has poor corrosion resistance and is prone to oxidation in humid environments. Aluminum core wire has a relatively low price and can be used as a substitute for copper core wire in some special occasions, such as high temperature environments.
Enamelled wire is a type of wire with copper or aluminum core wrapped with an insulating layer of paint. Enamelled wire has advantages such as good corrosion resistance, insulation, and wear resistance. However, the conductivity of enameled wire is low and it is prone to becoming brittle in high temperature environments.
Shielded wire is a wire wrapped with a metal shielding layer. Shielded wires have advantages such as good anti-interference, shielding, and corrosion resistance. But the price of shielded wire is relatively high, and in some situations where anti-interference requirements are high, it can be used as a substitute for ordinary wire.
Flat wire is a wire with two or more wires arranged side by side. Flat wires have advantages such as small size, light weight, and good flexibility. However, flat wires have low conductivity and are not suitable for use in situations where high conductivity is required.
When selecting electronic wiring harness assembly wires, it is necessary to comprehensively consider the actual application needs. If high current or signal transmission is required, copper core wire should be selected. If it needs to be used in high-temperature environments, aluminum core wire or shielded wire should be selected. If it needs to be used in humid environments, copper core wire or enameled wire should be selected. If it is necessary to use it in situations with high anti-interference requirements, shielded wires should be selected.

The low voltage resistance of the wiring harness comprehensive tester is insufficient

1. Wire quality issues Low voltage resistance testing may be affected by wire quality. If there are problems such as poor welding, breakage, or substandard material quality in the manufacturing process of wires, it can lead to an increase in low-voltage resistance. At this point, visual inspection and testing of the wires are required to confirm if there are any issues. If there are any issues, the wires need to be remanufactured or replaced.
