Best Busbar Selection: Copper Clad Aluminium Busbar 2012-10-29

 
The power transmission and distribution device is very important for the power supply in our daily life. The use safety of power is also very important because ignorance about the used power supply material will cause serious accidents and injuries. The power transmission and distribution device has different function parts, and the main power transmission busbars are mainly made of copper or aluminium. The copper busbars are more commonly used in the power transmission and distribution device. As a matter of fact, the aluminium busbars have much lower price than the copper busbars, but why people still choose copper busbars? Now, we will have a look at the reasons.
 
<span>The widespread use of any kind of busbar includes the factors of performance, weight, expansion and cost. The aluminium busbar has the advantages of low price, light weight and high storage, while the copper busbars are much higher in price. The copper busbars have the electrical conductivity of 0.0175&Omega; * mm2 / m, while the aluminium busbar has the electrical conductivity of 0.0295&Omega;*mm2/m. The differences on the electrical conductivity will not influence much about the busbar selection. But the aluminium busbar has a much higher coefficient of thermal expansion than that of the copper busbars. The aluminium busbar will deform easily, and the aluminium busbar will present in a snake shape after long time of use. The mechanical strength of the aluminium busbar is low, and the aluminium busbar will be brocken when the exterior force is too large.</span>
 
For use safety of power, the busbar selection must be careful, but how to lower the cost of using the busbars is an important problem. The copper clad aluminium busbar is then developed for meeting the requirements of maintaining the performance at a lower cost. The copper clad aluminium busbar is made by the technical principle that regular aluminium busbar is coated with copper, and a small amount of inert elements such as magnesium, manganese, etc. is added so that the galvanic corrosion between copper and aluminum can be avoided. The copper clad aluminium busbar has the advantages of good electrical conductivity, stress resistance, corrosion resistance, low cost, safe use, reliability, etc.
 
The copper clad aluminium busbar is the best busbar selection because of its super advantages over both the aluminium busbar and the copper busbars. With the innovation of busbar technology, the copper clad aluminium busbar will be more widely used for the power transmission and distribution device.
