Submersible 3 - Core Flat Cables

Submersible 3 - Core Flat Cables Pump cables is a specialized product to be used for submersible pumps in a deep well. The area of installation is physically restrictive, and the environment is very hostile.Raj Ratan Submersible 3 - Core Flat Cables is designed and manufactured keeping in mind these factors to achieve the highest possible degree of reliability.

Three core Flat Cables are manufactured with bright electrolytic grade copper with special PVC compound framing the core and the covering for longer durability.

Note :

The strand diameter is nominal however, construction of conductor is design to satisfy the requirements of conductor resistance as per IS:8130:1984. *As per conductor class 2 of IS:8130:1984 **As per conductor class 5 of IS:8130:1984
