What is XLPE
Polyethylene a thermoplastic material consisting of long chain hydrocarbon
molecules. At elevated temperature these molecules tend to move
relative to one another and material becomes increasingly deformable
and will eventually melt at a temperature around 110°C. The process of cross linking orvulcansation
consisting of producing chemical bonds at intervals between the
long molecular chains to give a "ladder" effect which prevent slipage
between moleculars and results in good thermal form stability.
Sioplas XLPE
Apart from conventional crosslinking technique using organic peroxide,
the latest new technique originally developed by DOW CORNING in
the UK in the early 1970s, and known by trade name SIOPLAS employs
a silane compound to form the crosslinking bridge between the PE
molecular chains. This method does not require heat or pressure
during extrusion as in conventional process and thus produces better
mechanical and electrical properties. The curing is done off-line,
production speeds are much higher and better control of cross-linking
properties is achieved.
The Advantages of XLPE Cables
XLPE cables are excellent in electrical, Thermal, Mechanical
& Chemical Properties. The various advantages of using XLPE
cables are:
 - Higher
current carrying capacity.
- Higher emergency & short circuit rating.
- XLPE cables are not prone to
fatigue damages due to vibrations or heating cycles.
- XLPE cables are light in weight
thus easy in handling during manufacture and installation.
- Lower dielectric losses.
- Better resistance to most chemicals,
such as ordinary acid, bases oils.
- Jointing & terminations are very easy.
- Better flexibility down upto
- 40°C.
