What are the advantages of copper stranded wire?
1, copper plays the role of conducting weak electrical signals, the 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 wire has the advantages of low density, high strength, low cost, etc., is the traditional pure copper single wire replacement 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 after 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 conductive properties
(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, easy to install, 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 inner 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 found in household electrical wires, it is also applicable 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 strands of such strands to form a bundle of rebar, which means "a bundle of 15 7 wires (total diameter of 5mm, each wire diameter of about 1.7mm), and a bundle of 7 wires (total diameter of 5mm, each wire diameter of about 1.7mm), and a bundle of 7 wires (total diameter of 5mm, each wire diameter of about 1.7mm). The total meaning is "a bundle of 15 strands of 7 wires (total diameter 5mm, each wire diameter of about 1.7mm) composed of stranded steel bars".
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.
The correct way to identify copper stranded wire?
1, first of all: look at the appearance of copper stranded wire. Copper stranded wire purchase need to start from the appearance of observation, generally good copper stranded wire it is relatively bright appearance, service has obvious damage and scratches, there will be no obvious oxidation reaction produced by the discoloration phenomenon. The outer edge of the color is more uniform, serves a black spot, serves a crack, the distance is uniform and regular. Meet the above criteria is a good choice of copper stranded wire.
2, second: look at the copper stranded wire specifications. The choice of copper stranded wire need to observe the scale and specifications of the line, the general copper stranded wire drawing needs to be within the scope of the provisions of the process can not exceed the standard, or else it is regarded as invalid stranded wire. Composition of stranded single line must meet the characteristics of uniform and neat, in line with the rules of the process.
3, again: look at the composition of copper stranded wire structure. Copper stranded wire purchase but also to observe the distribution and composition of the stranded wire structure, to see if there is a short line, lack of lines, loose strands, the phenomenon of lap strands, generally these can be observed with the naked eye, we need to carefully observe the inspection of the quality of copper stranded wire, can not choose unqualified products used in the production of wires and cables, which will result in serious safety accidents.
4, finally: look at the copper stranded wire welding process. Copper stranded wire purchase should also pay attention to whether the welding process is secure, the welded interface part is neat, serviced by the unevenness of the line. Welded interface should be repaired neatly, repair leveling, rubbing round, can not be tied, the welding head diameter generally can not exceed zero point two millimeters; two adjacent copper stranded wire welding should be maintained at a certain distance, spacing to be uniform.
