CNC machined C1100 copper conductive bus bars /customized pure copper flat bars/ T2 copper flat bar
Copper busbar:
We are one of the largest professional factory to produce the big size copper busbar, the sizes are customized according to customer drawing.
C11000 copper busbar, also known as copper busbar , is a high current conductive product. Copper busbar is an indispensable conductive material for manufacturing motor windings, high and low voltage electrical appliances, switch contacts, as well as wires for power supply and distribution installation, busbar trunking electrical engineering, etc. It is also widely used in smelting, electrochemical electroplating, chemical caustic soda and other ultra high current electrolytic smelting projects,
Characteristics of copper busbar:
1. Good conductivity and thermal conductivity;
Copper, second only to silver in terms of electrical conductivity and thermal conductivity, is the most conductive and thermally conductive metal among common metals. It can effectively accelerate heat dissipation in electrical equipment, thereby maintaining normal operation of the equipment. Therefore, it is widely used in the manufacture of conductive and thermally conductive devices.
2. Processing/Weldability
Copper has very high mechanical strength, is not easily deformed or broken, and has good processing characteristics, which can meet the requirements of process design such as stamping and bending. Good weldability, capable of cold and thermoplastic processing into various semi-finished and finished products. This allows copper bars to not only transmit current, but also carry certain mechanical loads.
3. Melting point/density
Its melting point is 1083 ℃, with no isomeric transformation, a relative density of 8.9, and a mass of about 15% heavier than ordinary steel in the same volume. Its strength and hardness are poor.
4. Corrosion resistance
The surface of copper bars, after being treated, can effectively resist corrosion and has good corrosion resistance in the atmosphere, seawater, certain non oxidizing acids (hydrochloric acid, dilute sulfuric acid), alkalis, salt solutions, and various organic acids (acetic acid, citric acid).
5. Service life
Its chemical properties are stable, combining cold resistance, heat resistance, pressure resistance, corrosion resistance, and fire resistance, and can be used for a long time in different environments. The service life of copper bars can be as long as or even longer than that of buildings.
Copper busbar classification:
According to the cross-section, it can be divided into rectangular, circular, D-shaped, U-shaped, and anisotropic shapes. Rectangular busbars with the same cross-section have lower resistance, larger heat dissipation surface, and higher current carrying capacity compared to circular, D-shaped, U-shaped busbars; Circular and D-type busbars have good skin effect and good electrical protection effect; U-shaped busbars are generally used in equipment with high current and high force effect requirements. Nowadays, rounded corners are generally used to avoid sharp discharge
According to the material, it is divided into copper busbar, aluminum busbar, and iron busbar. Copper busbar is widely used due to its high current carrying capacity, good corrosion resistance and force effect; Aluminum busbars are also used in low current, non coastal, and non petrochemical systems; The use of iron busbars is mainly considered economically and is mainly applied to PT connection lines.
According to their natural state, they are divided into hard busbars and soft busbars. Soft busbar is mainly used in places where connection is inconvenient and can absorb some force effects, such as inside circuit breakers.
