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.

Why semiconductor is called semiconductor not semiinsulator?
The purpose of semiconductors is to control the amount of conduction, not the amount of insulation.

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

Is diamond a semiconductor or not?
Diamonds conduct heat and electricity: this is the property tested by diamond probes. And in the technology sense of semiconductor, diamond is too expensive to be used for this purpose.

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.
