We all known that Copper busbar is a metallic strip or bar, typically housed inside switchgear, panel boards, and busway enclosures for local high current power distribution.
They are also used to connect high voltage equipment at electrical switchyards, and low voltage equipment in battery banks.
Copper has excellent electrical and thermal conductivity, high ductility, high melting point, can be joined easily by soldering and brazing, good corrosion resistance in most circumstances and low toxicity to humans (and also has an anti-microbial effect). Small diameter copper pipes can be relatively easily bent without kinking.
It is a constituent of many important engineering alloys including :
Many high performance aluminium alloys
So common uses include :
electrical conductors, especially flexible and semi-flexible wires.
domestic water pipes
piping in heat exchanges
as electrical shielding (in the form of foil)
heat sinks and thermal conductors
Occasionally as a premium roofing material (especially as it weathers to an attractive blue/green colour).
As a base for electroplating
As an anti corrosion coating on steel welding rods.
