The purpose of the semiconductor over XLPE is to equalize the electrical stresses over a large area.
as an insulation
for high voltage more than 11 KV and low current we can use XLPE cable.
The full form of XLPE is Cross-Linked Polyethylene. XLPE is a type of polyethylene in which the polymer chains are chemically linked, or cross-linked, to improve its thermal and mechanical properties. This cross-linking enhances the material's resistance to heat, pressure, and environmental stress, making it suitable for use in insulation for high-voltage cables and wires.
XLPE (cross-linked polyethylene) resin is a type of thermosetting polymer used in the manufacturing of electrical cables. It offers high thermal and chemical resistance, excellent electrical properties, and low water absorption. XLPE resin is commonly used in medium to high voltage power cables for transmission and distribution of electricity.

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.
LT XLPE is a type of power cable often used in computers. They are known to be able to take high voltage transfers and short circuit much less than other types.
