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.

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
