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.

What is the current carrying capacity of 32 sq mm copper cable?
It depends on the the number of cores, type of insulation, whether armoured or unarmoured, and method of installation. So, there is no simple answer. You must determine the current-carrying capacity from the Tables provided in BS 7671:2008 Requirements for Electrical Installations, or the equivalent used in your country.

Where would you use xlpe cable?
for high voltage more than 11 KV and low current we can use XLPE cable.
What is full form of the XLPE?
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.

What are the advantages of XLPE cables over paper insulated lead?
XLPE cable has high electric strength,mechanical strength,high-agcing resisting,environmental stress resisting anti-chemical corrossion,and it is simple construction,using convenient and higher operating of long term temperature.It can be laid with no drop restriction. Various of flame-retandant and non-flame retardant XLPE cable can be manufactured with three technology(peroxide,silance and irradiation crosslinking).The flame-retardant cable covers all kinds of low-smoke low-halogen,low-smoke halogen free,and non-smoke nonhalogenated and three classes of A,B,C. Some of special XLPE cable can be manufactured according to ther other standards required by customs. XLPE cable having higher long-term working temperature and greater current rating,at the same environment XLPE cable may be reduced size(nominal cross-section)1 or 2 class in comparison with paper
