Speciality cables
3 CORE FLAT CABLES
For troublefree working these
connecting cables are just as important as winding wires are for the submersible pump
motors.
" SHREE NAKODA " 3 Core
Flat Cables are manufactured keeping in mind the severely difficult conditions in which
these are required to operate. The individual flexible conductors are made from
electrolytic grade bright copper. The wires are drawn, annealed and bunched properly to
ensure long life. Each of these three flexible copper conductors is insulated with a
specially formulated PVC compound and the cores are laid-up in Flat Parallel Position. The
outer sheath of the cable is made from a special grade of abrasion resistant PVC compound
impervious to water, grease, oil etc.

Cables for sewage and slurry pumps should be able to withstand abrasion, prevent ingress of water along the inside of the cables and be resistant to acidic fluids and other chemicals. Bright yellow coloured double jacketed "SHREE NAKODA" cables are successfully running dewatering pumps. The range and size is as per the table.
