What is difference between PVC cable & XLPE cable?

Answer Posted / ashok sharma

XLPE has the following advantages over PVC insulated cables:
1. Higher current carrying capacity as it can withstand
higher temperature compared to PVC cable.
2.They have high overload capacity.
3.Lighter in weight, smaller bend radius, hence lesser
installation cost.
4.It has higher short circuit rating.
5.It has lower di -electric and constant power factor :
This results in saving of power losses.

L.A. (Lightening Arrester) is located at a place from where transmission line enters the transmitting substation. So L.A. (Lightening Arrester) is the first equipments which has to encounter with lightening, high voltage surges and switching surges. It has to absorb energy of lightening, high voltage surges, and switching surges. L.A. (Lightening Arrester) is made up of layers of semiconductors. If these layers can not tolerate energy released by lightening, high voltage surges, and switching surges the L.A. (Lightening Arrester) blasts.
