POLYCAB Elastomeric Insulated Cable Confirming to BS EN 50525-2-21.

Polycab offers a comprehensive range of Rubber flexible cable conforming to BS EN 50525-2-21 for various
application.

The highly flexible and robust Polycab Rubber cable makes its use in portable electrical equipment and
devices. The mechanical force involved in moving apparatus requires cables to withstand high degree of
wear and tear, extreme weather condition, oil/grease prone area and high heat zone. These flexible
rubber cables are also suitable for wide range of application in lighting, appliances or equipment including
heavy industrial equipment requires flexible connection to power supply.

Conductor: High conductivity bunched tinned copper conductor produced in-house from state-of-the art
Machine.

Insulation: In-house developed cross linked elastomeric compound ethylene propylene rubber (EPR) or
Ethylene vinyl acetate (EVA).

Sheath: In-house developed cross linked elastomeric sheathing polychloroprene (PCP) or

chlorosulphonated polyethylene (CSP) or ethylene vinyl acetate (EVA) or thermoplastic polyurethane
(TMPU) compound.

The construction based on the application and requirement of the user against BS EN 50525-2-21
