For trouble free working these connecting cables are just as important as winding wires for the submersible pump & motors. MEHAL CABLE 3 core flat cables are Manufactured keeping in mind the severely difficult conditions in which they are required to operate. The wires are drawn, annealed and bunched properly to ensure long life. Each of these three flexible copper conductors are insulated with a specially formulated PVC compound and the cores are laid-up in flat paralled position. The outer sheath of the cable is made from special grade of resistant PVC compound impervious to water, grease oil etc. Rigid test & checks at every stage from raw material through production and finally up to the finished product insure that MEHAL cables are of highest quality to meet the International Standard.
