Apply our equation Current carry capacity of 35sqmm bar 12 35 42 Amps. Copper current-carrying is equal to 12 times the total volume of the copper lenthbreaththickness.

Copper Busbar Current Rating

You are misreading the spec for the XLPE cable.

. Current Carrying Capacity CCC is the maximum rated current a conductor can carry during normal operating conditions. Current carry capacity of 35 sqmm bar 08 35 28 Amps. Calculating the current carrying capacity can be simplified by using common busbar configurations and graphical methods.

Free Air Conditions assume some air movement other than convection currents and may be applicable for outside installations. The total current carrying capacity of the busbar is 12 area 1000 sqmm 12 1200 Amps. Ad Find Deals on copper grounding busbar in Electrical on Amazon.

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. Skin Effect Ratio at 70 C. It solves the shortcomings of traditional copper braid busbars such as easy heat generation and high energy consumption.

High current is defined where the rated current is equal to or exceeds 800 Amps. Ive noted a rule of thumb for Copper busbar current carrying capacity of 12busbar widthbusbar thickness in Amps. The technical requirements for busbars match well with the material properties of copper.

Lets us have a simple example of 35 sqmm bus bar. Why is the current carrying capacity of Copper bar 12 Asqmm much less than even insulated copper conductor of the same cross-section considering an XLPE single core 1 sqmm copper conductor can carry 17 A as per data-sheet. The busbars are provided with extra copper within the conductor to allow a longer current carrying capacity than the coils in the event of a quench although this.
