For trouble free working, these connecting cables are just
important as winding wires are for the submersible pump motors.
Polycore 3 core Flat Cables are manufactured keeping in mind the
severe and difficult conditions in which they are required to
perform . The individual conductors are made from bright
electrolytic grade copper. The wires are drawn, annealed and
bunched properly to ensure flexibility and uniform resistance. Each
of the three copper conductors is insulated with a special PVC
compound and the cores are laid in flat parallel position . The outer
sheath of the cables is made from a special grade of abrasion
resistant PVC compound impervious to water, grease, oil, etc
3 CORE FLAT CABLES AS PER IS 694: 1990
Note: The strand diameter is nominal. However,
construction of conductor is designed to
satisfy the requirement 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.
THE FLAME RETARDENT ADVANTAGE
Note: The number of wires and strand
diameter will be such as to satisfy the
requirements of conductor resistance as
per IS 8130 : 1984
SELECTION GUIDE FOR 3 CORE FLAT CABLES
1) HP vs current: The full load current for submersible pump motors, 3 phase, 50 cycles, 415 – 425 v.
2) Derating factors: Multiply the current carrying capacity of the cable by factors given below for various
ambient temperatures.
