PVC INSULATED CABLESUniversal Cable (M) Berhad (UCMB), incorporated in 1967, has grown steadily to become the
Through its far sighted planning and unceasing product and service innovation, UCMB has
markets to aluminium rods. UCMB has achieved a distinguished reputation as a leading supplier of power and telecommunication cables to major corporations, both local and foreign.
The PVC insulated cables manufactured today by UCMB are internationally renowed for its world
PVC has been in use as an insulating and outersheating material for a long time. Since PVC has
applications including low power and control uses. Generally, they are two types of PVC, general purpose and heat resistance PVCs with maximum conductor temperatures of 70°C and 90°C respectively.
and machine tool wiring. Communications application use PVC coverings on a limited basis.
the insulation and jacketing material of choice for many common applications. these properties
low cost.
This catalogue serves as guide to UCMB’s manufacturing processes and standards in the production of PVC insulated cables, both armoured and unamoured, including one with reduce neutral conductor and a phase-to-phase voltage of 1000 volt. The conductor used is mainly plain annealed copper. other conducttors, such as tinned copper and aluminium are also available and
