ELASTOMERIC (RUBBER) CABLES
Elastomer (rubber) is an insulating material with high dielectric strength having a decent property of flexiblity ,the Elastorneric cables are suitable for applications for electric iron leads , reeling &unreeling application in mining, heater leads ,elevators cranes & other high dielectric & flexible application.The BMI CABLES are manufactures wire and cables to IS 9968 (Part-1) /1988 & Part -II ,IS 14494 , IS 9857/1990 For Welding Cables.

There are various type of compounds according to the grade & properties as per IS:6380 Such as a general purpose, heat resisting & high temperature insulation. The elastomeric cables are suitable for use where the combination of ambient temperature & temperature - rise due to load remains stable up to the following limits in the conductors.
 
BMI CABLES PRIVATE LIMITED is one of the leading manufacturers of varieties of Elastomeric Cables made of Natural and various types of Synthetic rubber compounds. The compounds based on EPR, CSP,NBR-PVC,EVA,Silicon are made in the most modernised plant by highly skilled hands to suit the specific operational regiments, continous R & D and upgraded production technology are the main features of Elastomeric Cables Division at BMI. The cables are manufactured in compliance with every National and International Standards.
