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.
