as an insulation
for high voltage more than 11 KV and low current we can use XLPE cable.

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.

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
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
