Power Cables

Cable Capacity

1.     For Cu Wire Current Capacity (Up to 30 Sq.mm) = 6X Size of Wire in Sq.mm. Ex. ...

2.     For Cable Current Capacity = 4X Size of Cable in Sq.mm, Ex. For 2.5 Sq.mm = 4×2.5 = 9 Amp.

3.     Nomenclature for cable Rating = Uo/U.

4.     where Uo = Phase-Ground Voltage, U = Phase-Phase Voltage, Um = Highest Permissible Voltage.

 

 

Minimum Bending Radius

·         Minimum Bending Radius for LT Power Cable = 12 x Dia of Cable.

·         Minimum Bending Radius for HT Power Cable = 20 x Dia of Cable.

·         Minimum Bending Radius for Control Cable = 10 x Dia of Cable.
