BUS BAR
T H A N K Y O U B Y :
Bus bar is a group of conductor, which is used to carry the current from one place to another place. in bus bar, material like bronze, aluminium, copper are used as a bus bar. aluminium is good to use, because it is cheap, less in weight. The bus bar's are manufacture in the shape of rectangle, square, and round tubes. The most common of the bus-bars are 40x4mm (160 mm); 40x5 mm (200 mm2); 50x6 mm (300mm2); 60x8 mm (480 mm2) ; 80x8 (640 mm2) and 100x10 mm (1000 mm).
WHY BUS BAR'S ARE USED IN ELECTRICAL SYSTEM:
In some case using of bus bar's are most useful then the using of cables
EXAMPLE: in a power plant or power distribution center, sometimes they handles high amount of power, for that cables aren't convenient. they might need a cable as thick as a firehose and six times as heavy to carry the current. If not cable can melt, In those cases, instead of using cable, we can just use slabs of metal instead.
ADVANTAGES OF BUS BAR :
* Bus bars reduce system cost
* Improve reliability
* Increase capacitance
* Eliminate wiring errors
* They also lower inductance and increase capacitance.
* The physical structure of bus bar offers unique features in mechanical design.
DISADVANTAGES OF BUS BAR :
- Commercially not viable if the number of switch gears is low
- Specialists needed for construction of the busbar system from a wiring diagram
- Lack of adapters for mounting different electrical devices on the busbar
- Special type of busbars needed to construct busbar system which can carry current more than 800 Ampear
