Can you use aluminum for a busbar?
All of which contribute to the electrical efficiency of the busbar trunking system. However, when compared by weight, aluminum is more electrically efficient. Again, this can be attributed to aluminum having a density 70 percent lower than copper, making it the perfect choice where busbar sizing is a non-issue.
What grade of aluminium is used for busbar?
According to the previous production experience, as for the oxidation production line (low voltage, high current), we use the most common 6061 aluminum bus bar. If it is used for mechanical equipment, it is recommended to use pure aluminum 1060 1070 series material.
How is aluminium busbar size calculated?
THUMB Rule for Busbar : For Aluminium : 0.7 Amps / 1 Sq.mm of Bar. For Copper : 1.2 Amps / 1 Sq.mm of Copper. Here the above mentioned rules are not standard.
What are the factors to be considered for busbar design?
The issues that need to be addressed in the design of busbar systems are:
- Temperature rise due to energy losses.
- Energy efficiency and lifetime cost.
- Short-circuit current stresses and protection.
- Jointing methods and performance.
- Maintenance.
Is 6061 aluminum a good conductor?
Both of these alloys have low resistivity, suggesting high conductivity, and are therefore conductive materials useful in electrical applications. 6061 is generally more suited for these uses, as it is more widely available, can be formed and welded easier, and is slightly more conductive than 7075 aluminum.
What is an aluminum bus?
Aluminum bus pipe is an extruded tubular product widely used in the construction of electrical components and equipment within switches, panel boards and enclosures within electric substations. These products are also used to connect high voltage and low voltage equipment.
What is aluminum bus?
Aluminum bus bars are often used as electrical conductors in power distribution systems, where heat can easily be dissipated. Because of the low value of the metal, it can be the best economic option for the application.
What is the meaning of EC grade Aluminium?
electrical conductor
Aluminum 1350, also referred to as EC (electrical conductor) aluminum, is the primary alloy utilized in aluminum magnet wire.
How do I know my busbar size?
Bus bar Cross Section Area as per Short Circuit= 50000X√ ((1.166/( 100×100)x(1+ 0.00403×85) x1. Bus bar Cross Section Area as per Short Circuit=626 Sq.mm. Select Higher Size for Bus bar Cross section area between 436 Sq.mm and 626 Sq.mm. Final Calculated Bus Bar Cross Section Area =626 Sq.mm.
What is the current density of aluminium busbar?
Current density is generally 0.8 A per sq.mm for aluminium & 1.6 A per sq.mm for copper.
Is standard for bus bar?
Busbars systems, or busbar supports are essentially heavy conductors, typically made of copper, which carry and distribute powerful electric currents to components that consume electrical power throughout an assembly.
How do you measure a busbar?
Who is the best aluminum bus bar manufacturer?
Watteredge is a top aluminum bus bar manufacturer and a leader in the design and manufacture of fabricated aluminum bus bars and aluminum bus bar systems for high current secondary AC and DC applications
When was the first aluminium busbar made?
The first aluminium busbars in the U.S.A. were made by ALCOA in 1895. these were rated at 20,000A and installed at ALCOA’s Niagara works.¹
What are the disadvantages of aluminium busbars?
The primary concern in the use of aluminium busbars is the jointing between aluminium, and to dissimilar metals such as plain and plated copper. This is addressed by the application of a patented plating process.
What is the current density of an aluminium busbar?
Ratings for single bars have been extrapolated from the chart on page 13 and other published data on aluminium busbars in switchboards. This reveals a current density of:- 1.1A/mm² to 700mm² 1.0A/mm² above 700 to 1200mm² and 0.8A/mm² above 1200 to 3200mm².
