Three Core Flat Cable

Thermal Compensating Silicon Coated Submersible Flat Cable

Current Carrying Capacity at 40°C(Amps) Comparison Chart

Important Notes:

  1. This Amp rating is valid only for standard submersible pumps/motors manufactured by reputed companies.
  2. The cable size is also subject to depth of borewell as voltage drop will affect its life & performance.
  3. This rating is not valid for assembled and repaired pumps/motors.


Silicon offers good resistance to extreme temperatures. At extreme temperatures, the tensile strength, elongation, tear strength and compression set can be far superior to conventional PVC. PVC has a carbon to carbon backbone which can leave them susceptible to ozone, UV, heat and other ageing factors that silicon can withstand well. This makes it one of the best elastomers of choice in many extreme environments.


  • Fully and Totally protected inner core with Safety Walls to prevent water penetration and heat transfer to another core.
  • Silicon coated sheath to protect core from External Heat, Moisture etc
  • Special Tyre type design for outer protection
  • Twin coated inner core for protection against U.V., Heat & Voltage Fluctuation
