As the cable cross section(C.S) increases, the
density of current (A/mm2) decreases due to skin effect.
Maximum AMPACITY |
Current Density A/mm2 |
|
1 mm2 | 13 A | 13 |
3* 150 mm2 |
350 A |
2.3 |
3 * 300 mm2 | 570 A | 1.9 |
3 * 400 mm2 | 680 A | 1.7 |
3 * 630 mm2

880 A |

the current passes in the outer layers and decreases gradually to be zero in the
inner layers
