Answer / dinesh lokhande

XLPE comes from the term cross linked polyethylene.
Crosslinked polyethlene, which results from a chemical
process of “cross-linking” of the molecular structure, has
eliminated defect of melting point 110ºC..


The features of cross-linked polyethylene
are as mentioned below in brief.
(1) High softening temperature and small heat distortion
(2) High mechanical strength under high temperature.
(3) Superior heat aging resistance.
(4) High resistance against stress cracking.
(5) Superior electrical characteristics.
(6) Light in weight.

Cross linked polyethylene insulated power cable (XLPE cable)
X - Cross
L - Linked
PE - Polyethylene

Answer / erharisheee51

Cross-linked polyethylene, commonly abbreviated PEX or XLPE.
PEX- or XLPE- insulated cables have a rated maximum
conductor temperature of 90°C and an emergency rating up to
140°C

Usage:

1.It is formed into tubing
2.predominantly in building services pipework systems,
hydronic radiant heating systems
3.Domestic water piping and insulation for high tension
(high voltage) electrical cables

Advantages:

Flexibility
Less materials cost
No fire risk during installation
No corrosion

Reliable

Disadvantages:
Can't use adhesives for pipe insulation
Degradation from sunlight.
Fittings somewhat more expensive.
Possible health effects.
