Bare Bright Copper Per Pound

 

Bare copper wire and bare conductor products per pound are called "bare wires and bare conductor products" with only conductors and no insulation layer. Each pound of bare copper bare copper wire is drawn from pure copper rods to become copper wires of various specifications. The surface is not coated with any conductive or insulating materials such as coatings and varnishes. It is commonly known as bare copper wire. Every pound of bare copper bare copper wire is It is copper metal, with a clean and smooth appearance, and the surface color is brass. In terms of physical properties, the bare copper wire is soft and has excellent electrical conductivity.

Bare copper wire per pound is the most basic category of wire and cable products. Mainly used for power cables, busbars, transformers, switches, plug-in components and connectors, etc. In motor manufacturing, copper alloys with high conductivity and high strength are widely used.

. In order to ensure that the current flows along the direction of the conductor and the electrical safety, external insulation suitable for the line voltage must be provided during installation, such as space intervals, insulator supports, etc. Therefore, this type of product itself does not indicate "use voltage". The technical discipline of this type of product is the research and development of conductive metal materials with high conductivity, high strength, high heat resistance, corrosion resistance, wear resistance, etc., and the process of non-ferrous metal pressure processing (hot rolling, cold drawing) Technology and equipment, preparation of conductive alloys, smelting and modification of high-purity non-ferrous metals, research and process technology development, etc.

 

 

It has good electrical conductivity, thermal conductivity, corrosion resistance and processing performance, and can be welded and brazed. It is not suitable for processing (annealing, welding, etc.) and use in a high-temperature reducing atmosphere.

 

 

1. Power system The wire and cable products used in the power system mainly include overhead bare wires, busbars (busbars), power cables (plastic cables, oil-paper cables (basically replaced by plastic power cables), rubber sheathed cables, and overhead insulated cables. ), branch cables (replacing some busbars), electromagnetic wires, and electrical equipment wires and cables for power equipment, etc.

2. Information transmission system The wires and cables used in the information transmission system mainly include local telephone cables, TV cables, electronic cables, radio frequency cables, optical fiber cables, data cables, electromagnetic wires, power communication or other composite cables, etc.

3. Mechanical equipment, instrumentation system This part is applicable to almost all products except overhead bare wires, but mainly power cables, electromagnetic wires, data cables, instrumentation cables, etc.

 

 

 

Copper with a high copper content per pound of bare copper bare copper wire, and the total content of other impurities is less than 1%.

Pure copper has a density of 8.96 and a melting point of 1083°C. It has good electrical and thermal conductivity, excellent plasticity, and is easy to process by hot pressing and cold pressing. It is widely used in the manufacture of wires, cables, brushes, and electric sparks.

2.Products that require good electrical conductivity, such as full-screen electric corrosion copper.

 

 

Each pound of bare copper wire 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 each pound of bare copper 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.
