Copper stranded wire use Copper stranded wire purchase and manufacturers recommended

Copper strands are not unfamiliar in our daily lives, and surely many people know it. The copper strand is a kind of building material and plays an important role in our daily life. Mainly used for appliance repair, welding machinery, a wide range of uses, copper stranded wire is different from the traditional twisted wire, relatively thicker than copper stranded wire, better conductive properties, can be applied to different industries and fields. However, what is the specific use of copper stranded wire ? Copper stranded wire has two types of hard copper stranded wire and soft copper stranded wire. There is a big difference between the two, and their use is different. Next I will introduce the use of copper wire and other related knowledge.

Copper Strand Specifications

Soft copper wire specifications are 15-7Φ5, 12-7Φ5, 9-7Φ5, etc. Take 15-7Φ5 as an example, 5 represents the wire diameter of nominal diameter 5.0mm, 7Φ5 represents 7 wires of this kind compose a strand, and 15 indicates that 15 strands of this steel strand constitute a bundle of steel bars. The overall meaning is “a bundle of steel bars consisting of 15 strands of 7 filaments (a total diameter of 5 mm and a diameter of approximately 1.7 mm per strand)”.

Copper Strand Features

1, the unique manufacturing process

The materials are manufactured using special processes that achieve metallurgical molecular bonding and long life.

2, soft structure, large surface volume, good heat dissipation.

High-temperature welding, no residue, no corrosive phenomenon. The surface copper layer is thicker (the average thickness is more than 0.3mm) and has strong corrosion resistance. The service life is (more than 30 years) and maintenance-free.

3, better electrical performance

The skin effect principle, excellent electrical conductivity, and its magnetic properties are conducive to the diffusion and transmission of electromagnetic fields.

4, safe and reliable

Use special connectors or chemical exothermic welding, joints firm, good stability.

5, convenient and quick

Take special heat treatment, can be made into a soft state, a large length, a large number of reduced linear connection points.

6, extensive use

Bundles or trays, less connection points, convenient transportation

Copper wire use

1, According to the different characteristics of hard copper and soft copper, they are used in different fields. Hard-stranded copper wires are often used in places where electrical conductivity is required and where tension is relatively high due to their strong tensile strength and low electrical resistance. For example, distribution lines and conductors of buildings, as well as power transmission lines. Cable aspects. Soft copper strands are generally thinner than hard copper strands, and their electrical conductivity is particularly high and tough. The most common thing we have is household electrical wiring. It is also used in electrical machinery as a conductor for power cables and communication equipment.

2. The difference between the performance of hard and soft copper strands is not too great. Manufacturers who have not used experience can easily ignore the gaps among the two. Choosing the wrong ones will cause great losses, so we must understand which ones we understand. More suitable for their own use.

3, Hard copper stranded wire has high tensile strength and high hardness. It is made by cold working with copper stretching. The soft copper stranded wire is formed on the basis of the hard copper stranded wire by heating it out of the residual, and is softer and more flexible than the hard copper stranded wire and can be bent.

  

How to buy copper wire

First of all: look at the appearance of copper wire

The purchase of copper strands needs to be observed from the appearance. Generally, the appearance of a good copper strand is relatively bright, and there are obvious damages and scratches. There will be no obvious discoloration caused by the oxidation reaction. Outside the color uniformity, there are dark spots in the service, there are cracks in service, the distance is uniform and regular. Meeting the above criteria is a good selection of copper strands.

Second: Look at Copper Strand Specifications

The selection of copper strands requires observation of the dimensions and specifications of the strands. Generally, the stranding of copper strands must be within the specified range and must not exceed the process standards. Otherwise, stranded strands are considered invalid. The single wires that make up the strand must meet the characteristics of uniformity and conformity to the process rules.

Again: look at the copper strand structure

The purchase of copper strands should also observe the distribution and composition of the strands to see if there are short lines, short lines, loose strands, and take-ups. Generally these can be observed with the naked eye. We need to carefully observe and inspect. The quality of copper strands cannot be used to produce unqualified products for the production of wires and cables, which can cause serious safety accidents.

Finally: Look at Copper Strand Welding Process

The purchase of copper strands should also pay attention to whether the welding process is reliable, whether the welding interface is neat or not, and there are line unevennesses. Welding interface should be neatly repaired, trimmed, rounded, can not handle, the diameter of the welding head generally can not exceed 0.2 millimeters; the welding of two adjacent copper strands should maintain a certain distance, division should be uniform.

Copper Strand Price

Because the specifications of copper stranded wire are 2.5 square, 4 square, 10 square, if these can not meet you, you can contact the merchant, generally can be customized. The specific price is best to consult the business is better, subject to their price. Finally, before placing an order, remember to look at the copper strand model.

Editor's summary: There is not much difference in the skills of hard and soft copper and copper strands, so manufacturers who are not proficient in this approach will often lose a lot because of neglecting these gaps. Therefore, you must understand clearly what you need before buying copper strands. Which one is it? The other is the choice of buying manufacturers, to the professional production of copper wire and other products manufacturers to buy, because the quality of this product to buy more secure.
