1) It is used for stress releaving at it will spead high voltage and not allowed to concentrate at or near to ground.
2) it is also helful in discharge as it work as a sensor in PD.

What is the full form of XLPE cable?
XLPE = Cross-Linked Polyethelene There are actually two semi-conductive layers on high voltage cable. One is between the actual conductors and the XLPE. The other semi-con is on outside of the XLPE insulation underneath the concentric neutral. The semi-con is used to equalize the electrical stresses over a large area. For example, most conductors are made up of multiple strands of copper or aluminum. The outer edge of the conductor bundle is not smooth. It has several ridges on the outer edge where the individual strands meet one another. These high spots will stress the insulation leading to a premature failure. The internal semi-con makes a smooth voltage level for the XLPE where it meets the conductor strands.

Why using semiconductor protection for HT cable?
In a HT cable there are 2 layers of semiconductor one on the conductor and second on the XLPE insulation. As we know semiconductor behaves as conductor when temperature rises. So when the HT cable is on load its conductor temperature rises due to this the semicon layer which is on conductor behaves like conductor and as a result overall cross section area is increased. now the second semicon layer which is over XLPE on temp rise behaves as conductor and used for dessipating heat out of conductor as the cable heat due to load.

What is the meaning of XLPE Electrical cables?
In the context of electrical cables, PVC and XLPE are two materials used as insulation. XLPE has got more capacity to hold on incase of high temperature. XLPE will not deteriorate it's insulating property until it reaches 90 degree celsius. It will not suddenly lose it's insulating property if the themperature jumps just above 90. But the overall life of the cable will be reduced. PVC can withstand temperatures only upto 70 degree Celsius. PVC is cheaper than XPLE, hence it's find it's place in market today. PVC is a thermo plastic where as XLPE is thermosetting plastic. PVC - Poly Vinyl chloride XLPE - Cross linked Poly Ethylene
