What are the application areas of bare copper wire?

1. Military clad conductor; Industrial grounding rod; cable braided shielded wire; connectors for various electronic components; Reinforced conductive core for special cables; transmission overhead lines and telephone lines; Conductors of parallel telephone subscriber communication lines; electrified railways, rail transit lines, bearing cables and conductor lines; Inner conductor material of cable subscriber wire and subscriber wire coaxial cable; Internal conductors for computer local area networks, access network cables, and field cables.
2. Application fields of hard copper wire and soft copper wire:
(1) Hard copper wire: Hard copper wire is often used in places that require conductivity and high tension requirements because of its strong tensile ability, low resistance and good conductivity, such as the distribution lines and conductors of buildings, as well as cables for verbal attack transmission.
(2) Soft copper wire: The common ones we see are household appliance wires. It is also suitable for motors, as conductors for power cables and communication equipment.
3. Application field of insulated copper wire: that is, there is a circle of insulating glue or plastic outside the copper wire. This kind of copper wire mainly uses the high tensile strength of copper wire, which can be used for special locks and brake wires on bicycles, battery cars, and motorcycles. It can also be extended to be used as a rope such as drying clothes.
What are the correct identification methods for bare copper wire?
1. Look at the appearance of the copper wire. The choice of copper wire needs to be observed from the appearance. Generally, good copper wire has a bright appearance, obvious damage and scratches, and no obvious oxidation reaction discoloration. The exterior color is uniform, there are dark spots and cracks, and the distance is uniform and regular. Meeting the above criteria is a good choice for copper wire.
2. Look at the specifications and models of copper wire. The choice of copper wire requires observing the size and specifications of the wire. Generally, the drawing of copper wire should be within the specified range and not exceed the process standard, otherwise it will be regarded as an invalid wire. The single-strand line needs to be uniform and comply with the process regulations.
3. Look at the structure and composition of copper wire. When buying copper wire, it is necessary to observe the distribution and composition structure of the wire to see if there are short wires, missing wires, loose stocks, and heavy stocks. Generally, these are observable with the naked eye. We need to carefully observe and test the quality of copper wire. Unqualified products cannot be selected to produce wires and cables, which will cause serious safety accidents.
4. Look at the welding process of copper wire. The selection of copper wire should also pay attention to whether the welding process is firm, whether the welding interface part is neat, and whether the existing line has unevenness. The welded joint should be kept neat, flat, sleek, and free of thorns. Under normal circumstances, the diameter of the sonotrode shall not exceed 0.2 mm; The welding of two adjacent copper wires should be kept at a certain distance and evenly spaced.
