what is the purpose of the armored for the power Or control
cable? How to select the type of the armored?
Answer Posted / santosh kawade
Purpose of armore for power or control cable:
1) Provide mechanical support for cable,
2) Protection from mechanical damages,
3) Provide parallel path for earthing and useful for cable
protection during earth fault.
There are two types of armores:
1) Flat type armore and
2) Round type armore
Depends upon cable size and area of use we can select cable.

generally in LT and MV motors we are using 3.5Coresx16,25,35,50 etc cable for supply.although motors is earthed at two point and having all protection.then why we are using that 1/2 core for earthing the motors.while in HT cable we are using only 3core cable for motor supply.generally lt and mv motors are delta connected and ht motors having star connection.whethere it is having any relation with winding connection( star or delta).all motors i am talking about are dol only.can anybody solve my confusion.thanks...
