Product Description

Copper busbar / new energy vehicle lithium battery aluminium radiator /  electric vehicle lithium battery C11000 copper radiator:  

 

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 or 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 ºC, 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.

 

Titanium clad copper bars/sheets/pipes/wire and other non-ferrous metals clad composite materials.
 

Titanium clad copper bus bars is a copper bar cladding with a certain thickness of titanium level, mainly used as a stand in plating, electrolysis, hydrometallurgy processes, because it has not only the original conductive property of the copper bar, but also protecting the copper bar from corroded by titanium level, therefore avoid the traditional copper bus bars shortcomings: danger and difficulty changing the anode metals, copper bar corrosion, heat generation caused by the electrical contact resistance in electrolysis and plating defects due to corroded and fallen copper compound, can greatly lower pollution of electrolyte. Now, the submerged Ti clad copper bus bar is the best choice for many industries including print circuit makers, steel (copper, gold) refining manufacturers.
 
Normally, we provide the first rate clad non-ferrous metal composites, mainly titanium clad copper and also including zirconium clad copper, 316L steel clad copper, titanium clad 316L steel plates, bars, tubes, composite wire, and multi-layer clad composites, etc. 
 
But, if you request that the material has this function above, then you must be sure that there are much stronger combination strength and much higher pasting rate between the copper bars and the titanium level, this can't be met by traditional mechanical combination methods. So in order to overcome it, our company R&D team summarizes three advanced processing technologies through several ten years of experiment: explosive welding, rolling cladding, and explosions-rolling cladding. Elegant group has successfully produced four individual layers titanium clad copper bars, at minimum, there is a core and an outer layer. Its sheared strength ≥ 130 Mpa, compact rate ≥ 98%, we can also supply the various specification of round, square, flat bars, the length of the bars can reach above 10 meters and can weld different shape and material together in according to the customer request. We could also make nickel clad copper bars, stainless steel clad copper bars, and zirconium clad copper bars series products through the same process technology.
 
Unsurpassed advantage performance of Titanium Clad Copper bus bar anode: 
(1) Good Shear and tensile strength: The shear and tensile strength is tested and guaranteed in accordance with GB, ASTM, and JIS.
(2) Perfect Elongation and Ductility: Elongation and Ductility of cladding metal is guaranteed in face bend (=cladding metal in tension), and the ductility of base metal is guaranteed in reverse bend (=cladding metal in compression).
(3) Good Hardness: The bonded interface is slightly hardened after explosion bonding. The interface can be softened by heat treatment to an original level. There exists no difficulty in bending and drawing works
(4) Excellent electrical conductivity: explosions-rolling process of the production make titanium and copper composite close completely with no delamination and therefore has good electrical conductivity, the composite strength of 135Mpa, and micro-resistance for 7.77 × 10-6Ω
(5). Fantastic Corrosion Resistance: Explosion bonding, a clad processing, guarantees excellent corrosion resistance of clad materials.
(6) Great weldability for connecting, capping and joining
(7) High reliability; High conductivity; Biocompatibility; Weld ability; Cost effective.
