PARTS OF CABLES
Current carrying capacity is an important aspect is the
selection of the optimum size of conductor. Voltage drop and short rating is
also very important aspect to select the economical and optimum size of
conductor. The safe current carrying capacity of an underground cable is
determined by the maximum permissible temperature rise. The cause of
temperature rise is the losses that occur in a cable which appear as heat.
There are various parts of a cable to be taken care of during
construction. The power cable mainly consists of
1. Conductor
2. Insulation
3. LAY for
Multicore cables only
4. Bedding
5. Beading/Armouring
(if required)
6. Outer
Sheath
