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

What is the difference between a sioplas line and a ccv line for manufacturing of xlpe cables?
sioplas is a temperature based curing and ccv is pressure based curing .this is general difference. gulab chand
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
What is the purpose of semiconductor over XLPE?
The purpose of the semiconductor over XLPE is to equalize the electrical stresses over a large area.
Define 2XFY in electric cable?

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.
What is the purpose of semiconductor over XLPE?
The purpose of the semiconductor over XLPE is to equalize the electrical stresses over a large area.
What is the function XLPE on cable?
as an insulation
