Approximate outer diameter and current loading capacity of cable
By comparing with common power cable of the same specification with PVC insulation and sheath,cable outer diameter is bigger by 2~10mm for cable with cross section of 95mm 2 or lower and by 12~20mm for cable with cross section of 120 mm 2 or higher. And cable weitht generally remains heavier by 4%~10%. About current-loading capacity allowed by soft power cable ,you can refer to that of VV series power cable of the same specifi-cation with a drop of 6%~10%.
Delivery Length
Delivery length of cable depends on both agree-ments with length error allowance of ±0.5%.
