An aluminum or copper conductor supported by insulators
that interconnects the loads and the sources of electric
power in an electric power system. A typical application is
the interconnection of the incoming and outgoing
transmission lines and transformers at an electrical
substation. Bus-bars also interconnect the generator and
the main transformers in a power plant. In an industrial
plant such as an aluminum smelter, large bus-bars supply
several tens of thousands of amperes to the electrolytic
process. See also Electric power substation.
major types of bus bar
(1) Rigid bus-bars, used at low, medium, and high voltage
The rigid bus-bar is an aluminum or copper bar, which is
supported by porcelain insulators.
(2) Strain bus-bars, used mainly for high voltage
The strain bus-bar is a flexible, stranded conductor which
is strung between substation metal structures and held by
suspension-type insulators.
(3) Insulated-phase bus-bars, used at medium voltage
The insulated-phase bus-bar is a rigid bar supported by
insulators and covered by a grounded metal shield. The main
advantage of this system is the elimination of short
circuits between adjacent phases.
(4) Sulfur hexafluoride (SF6)-insulated bus-bars, used
in medium- and high-voltage systems
The sulfur hexafluoride-insulated bus-bar is a rigid
aluminum tube, supported by insulators and installed in a
larger metal tube, which is filled with high-pressure
sulfur hexafluoride gas.
According to size 3 types
* tubular bus bar
* solid bus bar
* flat bus bar
According to capacity 4 type
* Extra high voltage bus
* high voltage bus
* medium voltage bus
* low voltage bus
