Soft Drawn Copper Wire

Bare copper wire refers to a copper wire drawn from a pure copper rod without any coating, varnish and insulating material on the surface, commonly known as bare copper wire. Smooth, copper finish color. In terms of physical properties, the bare copper wire is soft and has excellent electrical conductivity.

Bare copper wire is the most basic category of wire and cable products. Some products of bare copper wire can be used as conductive wires of wires and cables; another part of products are used as components in motors, electrical appliances, transformers and other equipment.

Bare copper wires can also be processed into various shapes according to needs, such as flat wires, round wires and various types of wires, etc., and can also be combined into various stranded wires and multi-stranded wires by combining multiple bare copper wires.

The properties of copper are ductility, thermal conductivity, electrical conductivity, and diamagnetism. Copper is a tough, soft, malleable purple-red and shiny metal, also known as copper. 1 gram of copper can be drawn into 3,000-meter-long filaments, or pressed into more than 10 square meters of almost transparent copper foil. Pure copper has high electrical and thermal conductivity, second only to silver, but copper is much cheaper than silver. The color of copper is similar to gold, and the color of hydrated copper ions is blue. Metallic copper has certain toxicity, because it is not easy to dissolve, and its toxicity is much weaker than that of soluble copper salts. Copper processed by specific processing methods is not toxic.

Copper is a non-ferrous metal that is very closely related to human beings. It is widely used in electrical, light industry, machinery manufacturing, construction industry, national defense industry and other fields. It is second only to aluminum in the consumption of non-ferrous metal materials in my country. For example, the application of copper in the power industry: power transmission, wire and cable, busbars, transformers, switches, plug-in components and connectors, etc. Motor manufacturing, stator, rotor and shaft head, hollow wire, etc. Communication cables and residential electrical wiring require large amounts of copper conductors.

Bare copper wires can be processed and widely used in the fields of cables, ultra-high voltage cables, communication cables, marine cables, automotive wires, photovoltaics, electronics, electromechanical and other fields.

The physical properties of copper are: copper is a fuchsia metal with a density of 8.92 grams per cubic centimeter. The melting point is 1083.4±0.2°C, and the boiling point is 2567°C. Has good ductility. Good thermal and electrical conductivity. The valency is usually +2, but also +1 (trivalent copper only appears in a few unstable compounds, such as potassium cuprate KCuO2). Flame color: green.

Bare copper wires must be produced and inspected according to the standards of GB/T 3953 "Electrical Round Copper Wire" and GB/T 4909 "Test Methods for Bare Wires".

After the bare copper wire is produced, it must be packaged, stored, handled and transported in strict accordance with customer and industry standards to ensure that the product is free from moisture and damage.

Q.Can bare copper wire be used for outdoor applications?

Bare copper wire can be used for outdoor applications, but it is important to ensure that it is properly grounded and protected from moisture, corrosion, and other environmental factors.
