Rubber Cables

rubber-cableIn keeping with the company’s commitment to technological advancement, elastomer materials such as Polychloroprene (PCP), Chloro-Sulphoneted Polyethelene (CSP), Nitrile Rubber / PVC blends, Ethylene Propelene Rubber (EPR), Ethylene Vinyle Acetate (EVA) and Silicone have been specially compounded to meet numerous heat oil and fire resisting requirements. In the recent years KEI has also developed special Elastomeric Fire Survival Cables for power, control and instrumentation wiring.

Elastomeric compounds for insulating and sheathing of cables are formulated to meet the requirement of IS 6380, BS 6899, IEC 60502 and other international specification.
