How do you calculate the current carrying capacity of aluminium busbar?
Hence the formula for calculating current carrying capacity,
- Copper: Copper busbar current carrying capacity = 1.2 * Busbar width in mm * Thickness in mm Amps.
- Aluminium: Aluminium busbar current carrying capacity = 0.8 * Busbar width in mm * Thickness in mm Amps.
- Iron Busbar.
- GI Bus bar.
- Silver Bus Bar.
- Example:
How is busbar current carrying capacity calculated?
Which means, take a copper bus bar of 100 mm width and 10 mm thickness, the area of the copper bus bar is 10 * 100 sqmm. The total current carrying capacity of the busbar is 1.2 * area => 1000 sqmm* 1.2 =1200 Amps. Hence the total current carrying capacity of the copper 1200 Amps of 100mm width and 10 mm thickness.
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. i.e They used 0.75 Amps / 1 Sq.mm of Bar & 1.4 Amps / 1 Sq.mm for Aluminium & Copper Respectively.
How is busbar Ampere calculated?
Temperature rise of Bus Bar Bar during Fault (θt=θ1-θ)=100°C. Ambient Temperature (θn) =50°C. Maximum Bus Bar Temperature Rise=55°C. Total No of Circuit= 3 No….(1) De rating Factors for Bus bar:
| Altitude of installation site (Meter) (K8) | De rating Factor |
|---|---|
| 2900 | 0.84 |
| 3000 | 0.83 |
| 3300 | 0.82 |
| 3500 | 0.81 |
What is the current density of Aluminium busbar?
The more popular thumb rule being followed in India is to assume current density of 1.0 Amps / Sq.mm for Aluminium and 1.6 Amps for Copper for any standard rectangular conductor profile.
What is the current density of Aluminium?
Aluminum has a density of 2.7 grams per cubic centimeter no matter how much of it you have.
How is Aluminium busbar weight calculated?
To find out the total weight per unit of your aluminium extrusion simply multiply the kg/m by the length of the finished product.
How does Aluminium bus bar calculate weight?
Is standard for Aluminium busbar?
Standard Aluminium pipes of minimum size 4″, 3″, 2.5″ and 1.5″ will be used for busbar of 400KV, 220 KV, 132 KV and 33 KV switchyard respectively.
How does aluminium bus bar calculate weight?
What is current carrying capacity formula?
Cable Capacity For Cable Current Capacity = 4X Size of Cable in Sq.mm, Ex. For 2.5 Sq.mm = 4×2.5 = 9 Amp.
