XLPE Insulated Power CablesUniversal Cable (M) Berhad was incorporated in 1967 as a private company
billion, Universal Cable shares the group’s extensive network for synergistic integration in varied areas of cable technology.
Universal Cable, together with its subsidiary companies, cover a broad
telecommunication and instrument cables, rubber insulated cables and electrical grade aluminium rods. Continued capital investment has enabled Universal Cable
materials to produce better and more costeffective products for its customers.
With a strong emphasis on customer satisfaction, Universal Cable and its subsidiaries are constantly expanding their product range to enhance its position as a major supplier of power and telecommunication cables to local industries and increase its prominence abroad.

WHAT IS XLPE?
polyethylene”. Polyethylene has a linear molecular
chemically bonded as shown in B are easily deformed
in a three dimensional network as shown in C and D,
have strong resistance to deformation even at high
temperature.
Cross linked polyethylene is produced from polyethylene
under high pressure with organic peroxides as additives.
The application of heat and pressure is used to effect the
cross linking. This causes the individual molecular chains
to link with one another which in turn causes the material
to change from a thermoplastic to an elastic material.
and high voltage cables is their low dielectric loss. The
dielectric loss factor is about one decimal power lower
than that of paper insulated cables and about two decimal
powers lower than that of PVC-insulated cables.Since the
dielectric constant is also more favourable the mutual
charging currents and earth-leakage currents in networks
without the rigid star-point earthing.

MANUFACTURING PROCESS OF XLPE CABLES
integrated high performance extrusion line which consists of a triple-layer crosshead and a water-free Completely Dry Curing and
The conductor is paid off continuously through a metering capstan (which is the line speed master point), a triple extruder
Using a group of three extruders, the triple crosshead allows simultaneous extrusion of the cable insulation and two semiconducting
screens with a high degree of smoothness and no voids or introduction of extrernal contaminants. Precise and stable temperatures
The various functions of our integrated extrusion line such as line speed and curing tube temperatures synchronisation are
parameters can be preset on the control unit and closed circuit TV system is used to ease the running of the lines.

STRUCTURAL DESIGN AND PERFORMANCE OF XLPE CABLES
have, in general, circular conductors and only single core
construction is adopted for the latter. Conductors may
be of compacted stranded aluminium or stranded copper
from sharp juts that could damage the insulation due to
high local electric stresses.
with extruded cross-linked semi conducting screens to
a smooth circular envelope around the conductor. This
individual wires and hence the electrical stress around
the conductor. While the insulation screen can be either
strippable or bonded for MV cables depending on the
customer’s option, bonded screen is used exclusively for
high voltage cables.
sectional area of this metallic screen is determined in order to satisfy the phase to earth fault level in the network.

PROCESS OF XLPE CABLES
applied with a conductor temperature of 130ºC for
emergency overload conditions, it must be understood
that the erecting and laying conditions necessary to allow
for those temperatures must be accurately carried out
and controlled during installation in order to restrict
thermomechanical problems. To be realistic, emergency

to cope with some concerns in the laying conditions.

function. Tests listed here include high voltage tests,
conductor resistance test, insulation resistance tests and
voltage tests on protective sheath coverings.
Type Tests
These tests are used to calibrate and validate cable design
type and they include bending tests, thermal stability tests,
impulse voltage tests, head distortion tests, corona level
tests and dielectric thermal resistance tests.
Special Tests
These tests are conducted to ensure major design
changes to cables conform to proper performance
thresholds.
After Installation Tests
These tests are to determine and ensure that cables
installed are in optimum operating conditions. Conductor
