How To Choose Copper Stranded Wire Correctly

How to choose copper stranded wire correctly

1. Look at the appearance and luster of the copper wire.

Generally, the appearance of the better copper stranded wire is relatively bright, there is no obvious damage and scratches, and there will be no obvious oxidation reaction to cause discoloration. The gloss of the appearance is relatively symmetrical, and there are no black spots and cracks. , the distance is relatively uniform, so the above criteria must be met.

2. Look at the specifications and models of copper stranded wires.

The selection of copper stranded wire needs to observe the size and specification of the wire. Generally, the drawing of copper stranded wire must be within the specified range and cannot exceed the process standard, otherwise it will be regarded as an invalid stranded wire. The single wires that make up the stranded wire must meet the characteristics of uniformity and neatness and conform to the process rules.

3. Look at the composition of the copper stranded wire.

Observe the distribution and composition of the stranded wire to see if there are short wires, missing wires, loose strands, or stranded strands. Generally, these can be observed with the naked eye. We need to carefully observe and inspect the quality of the copper stranded wire. Substandard products are used to produce wires and cables, which can cause serious safety accidents.

4. Look at the copper stranded wire welding process.

The purchase of copper stranded wires should also pay attention to whether the welding process is reliable, whether the welded interface parts are neat, and whether there is any unevenness in the lines. The welded interface should be neatly maintained, flattened, rounded, and not sticky. The diameter of the welding head should generally not exceed 0.2 mm; the welding of two adjacent copper stranded wires should maintain a certain distance.
