XLPE Insulated Power Cables - Cable

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?

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.

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

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
