INTRODUCTION
Leader Cable Industry Berhad (LCIB), incorporated in 1976, has grown steadily to become the
country’s single largest cable manufacturer today since its 1990 merger with Universal Cable
(M) Berhad under the flagship of its parent, Leader Universal Holdings Berhad (LEADER)
Through its far sighted planning and unceasing product and service innovation, LCIB
has successfully cultivated a manufacturing profile of an extensive range of cable
and wire products.
From household cables, XLPE cables, telecommunication cables for both
domestic and export markets to aluminium rods and enamelled wires, LCIB
has achieved a distinguished reputation as a leading supplier of power and
telecommunication cables to major corporations both local and foreign.
Today, as a subsidiary of the LEADER group of companies, LCIB has
one of the most advanced facilities for manufacturing telecommunication
cables in the Asia Pacific region.
LCIB’s telecommunicatin cable products include internal wires, jumper
wires, switchboard cables, multi-pair telephone cables and integral
bearer cables. Integral bearer cables are polyethylene insulated, unit twintype and moisture barrier sheathed. Telephone cables include P.E.U.T.F.F.
(polyethylene insulated, unit twin-type, fully-filled, polyethylene sheathed) and
P.E.U.T. (polyethylene insulated, unit twin-type, moisture barrier polyethylene
sheathed) construction types. P.E.U.T. type telephone cables are normally used for
local primary and junction network.
The telecommunication cables manufactured today by LCIB’s manufacturing processes and
standards in the manufacturing of telecommunication cables.

TELECOMMUNICATION
CABLE
The diverse application environment in the telecommunication and information technology
sectors requires a wide range of cable solutions. Today, two main configurations of cables
are in use : paired cables and quad cables. The type of configuration used depends on the
telephone system standard that is adopted by various countries. However, to satisfy different
customer requirements, we have the capability to manufacture both paired and quad
configurations.
The manufacturing process of telephone cables involves several processes.
However, depending on the cable specifications as provided by the customer,
certain processes may be by-passed or added.
The materials used in the manufacture of telephone cables and wires are
carefully selected and controlled to ensure sustained reliable service in all
products. Conductors used are annealed solid high conductivity copper
which are drawn to the required sizes prior to insulation. The insulation
material may be extruded solid or foam skin polyethylene. Some cables
which are used in internal applications may also be insulated with
polyvinyl chloride (PVC). These insulated wires are then twinned to form
pairs or alternatively, four wires are twisted to form a quad configuration.
Generally, cables are then constructed from the basic insulated elements
of either pairs or quads, which are twined and assembled into the
required final cable size. Customers may request for jelly-filled cables
depending on their application requirements. In such specifications,
an approved electrical grade of petroleum jelly is applied to fully fill the
interstices of the cable. A layer of mylar tape is then applied over the jellyfilled cable.
Where specified by the customer, a moisture barrier sheath may be helically or
longitudinally applied. Metallic screens, drain wires and rip cords can also be applied if
specified in the customer’s requirements.
The telephone cable then undergoes a final sheathing process where the outer jacket is
extruded over the cable to provide protection from physical stress.
Through the use of state-of-the-art manufacturing technology that is matched by technically
experienced personnel, we have been able to provide a range of well-engineered and cost
effective telephone cable solutions for customers both locally and internationally.
