The so-called copper stranded wire is a new type of composite wire made of high-quality low-carbon steel as the core, copper-plated and processed, a number of single wires stranded according to a certain law. Copper stranded wire is a kind of power transmission and distribution, electrical devices (such as transformers, electric furnaces) and electronic and electrical equipment, silicon controlled components of the soft connection line. In addition, copper stranded wire can also be used for electrical work grounding wire. Copper stranded wire is stranded single wire around the stranding axis of equal angular velocity rotation and stranded wire uniform forward motion to realize. Copper stranded wire can be divided into two types: hard copper stranded wire and soft copper stranded wire. They each have their own characteristics and uses.
What are the advantages of copper stranded wire?
1, copper plays the role of conducting weak electrical signals, steel wire plays a supporting role. According to the different methods of copper wrapped to the steel wire, mainly divided into electroplating, cladding, hot casting / dipping, and electroforming. The product has both the strength and toughness of steel and the good conductivity and corrosion resistance of copper. Compared with copper single line has the advantages of low density, high strength, low cost, etc., is the traditional pure copper single line of newer products.
2, the use of copper stranded wire can make the operating temperature down, compared with the same cross-sectional area of single-stranded wire, stranded wire has a higher mechanical flexibility. Widely used in high "Q" value lines.
3, copper stranded wire is made of high quality copper wire goods tinned soft copper wire. Processing process through the tough refining treatment, the finished product is soft, neat appearance, beautiful.
4, hard copper stranded wire and soft copper stranded wire advantages:
(1) hard copper stranded wire: strong resistance to tension is relatively strong, small resistance and good conductivity
(2) soft copper stranded wire: usually finer than hard copper stranded wire, its conductivity is particularly high, and toughness.
5, insulated copper stranded wire advantages: high tension resistance.
What are the advantages of copper stranded wire process?
1, the manufacturing process is unique: the use of cold rolling and hot drawing production process, to achieve a high degree of combination of copper and steel.
2, excellent anticorrosion performance: the surface of the copper layer is thicker (average thickness of more than 0.3mm), corrosion resistance, service life of up to 30 years or more.
3, better conductivity: due to the surface layer of copper material has excellent conductivity, so that its own resistance is much lower than conventional materials.
4, the use of a wide range: the product is suitable for different humidity, temperature and PH value of the soil conditions.
5, the use of safe and fast: complete accessories, the use of special connecting tube or the use of the company's production of hot melt flux connection, solid joints, convenient installation, greatly improving the construction efficiency.
6, construction cost reduction: compared with the traditional use of pure copper material grounding, the cost of a large degree of decline.
What are the application areas of copper stranded wire?
1, military coated wire conductor; power industry grounding rods; power cable braided shielding wire; various electronic components of the connector; special cables to strengthen the conductive core; power transmission and telephone lines of the overhead line; parallel dual-core telephone user communication line conductor; electrified railroads, rail transit line bearing cable and skidding line; cable TV subscriber line and into the home line coaxial cable inner conductor material; computer LAN, Access network cable, field cable conductor.
2, hard copper stranded wire and soft copper stranded s line application areas:
(1) hard copper stranded wire: hard copper stranded wire as a result of its strong resistance to tension is more knot, resistance is small conductive function is good, so it is often used for the need to conduct electricity and in the tension on the requirements of higher places, such as power distribution lines and the conductor of the building, as well as rows of power transmission cables.
(2) soft copper stranded wire: we are most commonly used in household electrical wires, it also applies to electrical machinery, as power cables and communication equipment conductors. Soft copper strand specifications are 15-7Φ5, 12-7Φ5, 9-7Φ5, etc. Take 15-7Φ5 as an example, 5 means that the nominal diameter of 5.0mm steel wire, 7Φ5 means that 7 such wires to form a strand, and 15 means that 15 such strands to form a bundle of steel, the total meaning is that "a bundle of 15 7 wires (total diameter of 5mm, the wire diameter of about 1.7mm), and the wire diameter of about 1.7mm, the wire diameter of about 1.7mm. Diameter of about 1.7mm) strand composed of rebar.
3, insulated copper stranded wire application: that is, copper stranded wire outside a circle of insulating rubber or plastic. Made of such copper stranded wire is mainly the use of copper stranded wire of higher tensile characteristics, can be used for special locks, bicycles or battery cars, motorcycles on the brake line. It can also be extended to be used as a rope for drying clothes and so on.
