How to distinguish the quality of electronic wire harness materials?

Jan 17,2024

The quality of a wire mainly depends on the following factors:
Conductor material: The conductor material of a wire is generally copper or aluminum. Copper wires have better conductivity than aluminum wires, but their prices are also relatively high. The conductivity of aluminum wire is slightly lower than that of copper wire, but it is relatively cheap.
Conductor cross-section: The larger the conductor cross-section of a wire, the better its conductivity.
Conductor diameter: The thinner the conductor diameter of a wire, the poorer its conductivity.
Conductor insulation: The conductor insulation layer of a wire should have good insulation performance to prevent leakage.
Insulating sheath
The quality of insulation sheath mainly depends on the following factors:
Material: The material of the insulation sheath is generally plastic or rubber. Plastic insulation sheaths have better heat resistance, wear resistance, and flame retardancy than rubber insulation sheaths, but their prices are also relatively high. Rubber insulation sheaths have poor wear resistance and flame retardancy, but they are relatively inexpensive.
Thickness: The thicker the insulation sheath, the better the insulation performance.
Strength: The stronger the insulation sheath, the better its wear resistance.
Wiring terminals
The quality of wiring terminals mainly depends on the following factors:
Material: The material of the terminal block is generally copper or brass. The conductivity of copper terminals is better than that of brass terminals, but the price is also relatively high. The conductivity of brass terminals is slightly lower than that of copper terminals, but they are relatively inexpensive.
Structure: The structure of the wiring terminals should be reasonable and easy to connect and disassemble.
Strength: The stronger the strength of the wiring terminal, the better its durability.
Binding materials
The quality of binding materials mainly depends on the following factors:
Material: The binding material is generally made of plastic or metal. Plastic binding materials have better wear resistance and flame retardancy than metal binding materials, but their prices are also relatively high. The wear resistance of metal binding materials is poor, but the price is relatively cheap.
Strength: The stronger the binding material, the better its durability.
How to judge the quality of electronic wire harness materials
When selecting electronic wiring harnesses, the quality of electronic wiring harness materials can be judged through the following methods:
Appearance: The appearance of electronic wiring harnesses should be smooth and neat, without obvious scratches, deformations, and other defects.
Smell: The odor of the electronic wiring harness should be odorless.
Touch sensation: The hand of the electronic harness feels soft and elastic.
Pull test: Pull the electronic wiring harness to see if it is prone to breakage.
Disassembly test: Disassemble the electronic harness and check the quality of the wires, insulation sheaths, wiring terminals, and binding materials.

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.
