Purchase of copper stranded wires for copper stranded wires and manufacturer recommendations

Copper stranded wire is no stranger to our daily lives, and many people must know it. Copper stranded wire is a type of building material and plays an important role in our daily lives. Mainly used in home appliance repairs and welding machinery, it has a wide range of uses. Copper stranded wire is different from traditional stranded wire. It is thicker and has better conductivity than traditional copper stranded wire. It can be used in different industries and fields. But what are the specific uses of copper stranded wire? There are two types of copper stranded wire: hard copper stranded wire and soft copper stranded wire. There is a big difference between the two and their uses are also different. Next, I will introduce to you the uses of copper stranded wire and other related knowledge.

Copper stranded wire specifications

Soft copper stranded wire specifications include 15-7Φ5, 12-7Φ5, 9-7Φ5, etc. Taking 15-7Φ5 as an example, 5 means the nominal diameter is 5.0mm Steel wire, 7Φ5 means that 7 such steel wires form a steel strand, and 15 means that 15 such steel strands form a bundle of steel bars. The general meaning is "a bundle consists of 15 7 wires (total diameter 5mm, each The wire diameter is about 1.7mm) composed of steel strands."

Characteristics of copper stranded wire

1. Unique manufacturing process

The material is manufactured using a special process, achieving metallurgical molecular bonding and long service life.

2. Soft structure, large surface volume and good heat dissipation effect.

Using high-temperature welding, there is no residue and no corrosive phenomena. The surface copper layer is thick (average thickness is greater than 0.3mm), has strong corrosion resistance, long service life (more than 30 years), and is maintenance-free.

3. Better electrical performance

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

4. Safe and reliable

Using special connectors or chemical exothermic welding, the joints are firm and stable.

5. Convenient and fast

Using special heat treatment, it can be made into a soft state, with a large length and a large number of straight-line connection points.

6. Wide usability

Packed in bundles or reels, with fewer connection points and easy transportation

Uses of copper stranded wire

1. According to the different characteristics of hard copper stranded wire and soft copper stranded wire, they are used in different fields. Hard copper stranded wire has strong tensile strength, low resistance and good electrical conductivity, so it is often used in places that need to conduct electricity and require relatively high tension, such as distribution lines and building conductors, as well as power transmission lines. Cable aspect. Soft copper stranded wire is usually thinner than hard copper stranded wire, has a particularly high conductivity and is tough. The most common ones we see are household electrical appliance wires, which are also used in electrical machinery as conductors for power cables and communication equipment.

2. The difference in performance between hard copper stranded wire and soft copper stranded wire is not very big. Manufacturers without experience in use will easily ignore the difference and choose the wrong one, which will cause great losses, so it must be To understand its functions, you need to know which one is more suitable for your use.

3. Hard copper stranded wire has high tensile strength and high hardness. It is made of copper drawn and cold processed. Soft copper stranded wire is made by heating out the residue of hard copper stranded wire. Compared with hard copper stranded wire, it is softer, more elastic and can be bent.

How to choose copper stranded wire

First of all: look at the appearance of copper stranded wire

When purchasing copper stranded wire, you need to start by observing the appearance. Generally, good copper The appearance of the stranded wire is relatively bright, with obvious damage and scratches, and no obvious discoloration caused by oxidation reaction. The color on the outside is relatively uniform, with some dark spots and cracks at even and regular intervals. Meeting the above standards is a good choice for copper stranded wire.

Secondly: Look at the specifications and models of copper stranded wires

The selection of copper stranded wires requires observing the size and specifications of the wires. Generally, the drawing of copper stranded wires must be within the specified range and cannot exceed workmanship standards, otherwise it will be regarded as invalid stranded wire. The single wires that make up the twisted wire must be uniform and neat and comply with process rules.

Again: Look at the structure and composition of copper stranded wires

When purchasing copper stranded wires, you must also observe the distribution and composition of the stranded wires to see if there are short wires, missing wires, or loose strands. , The phenomenon of stranding can generally be observed with the naked eye. We need to carefully observe and inspect the quality of copper strands. We cannot choose unqualified products to produce wires and cables, which will cause serious safety accidents.

Finally: Look at the welding process of copper stranded wires

When purchasing copper stranded wires, you should also pay attention to whether the welding process is reliable, whether the welded interface part is neat, and whether there are lines or lines. Flat phenomenon. The welding interface should be neatly maintained, smoothed, rounded, and should not be pinched. The diameter of the welding head should generally not exceed 0.2 millimeters; the welding of two adjacent copper strands should be kept at a certain distance, and the separation should be even.

Copper stranded wire price

Since the specifications of copper stranded wire are 2.5 square meters, 4 square meters, and 10 square meters, if these do not satisfy you, you can contact us Merchants can generally customize. For specific prices, it is best to consult the merchants, and the prices they give shall prevail. Finally, remember to look at the sample of copper stranded wire before placing an order.
