Submersible Flat Cables
Export-grade submersible flat cables designed for submersible pump installations.
Technical data sheet
Submersible Flat Cable (3-Core / 3-Core+E)
Submersible flat cable engineered for connection between submersible pump motors and surface control panels. EPR / XLPE insulation with PCP / heavy-duty PVC sheath provides reliable performance in submerged borewell water.

Salient Features
- Flat parallel construction — easy column-mount routing without twisting
- EPR / XLPE insulation — high dielectric strength, heat resistance
- PCP / heavy-duty PVC sheath — abrasion, oil, water resistance
- Flexible Class 5 copper conductor — fatigue resistant in long drops
- Suitable for permanent submersion in clean borewell water
- Factory-sealed gland-end on motor side (in pumpset assembly)
- Hot-shrinkable / cold-applied joint kits for field splices
- Conforms to IS 9968 / IS 694
- Black sheath standard (custom colours on request)
- Distance markings every metre for asset traceability
Applications
- V3 / V4 / V5 / V6 / V8 submersible pump motor cabling
- Borewell pump installations (vertical drop)
- Sewage submersible pump cabling
- Dewatering submersible pump cabling
- Solar submersible pump systems
- Industrial submersible motor installations
Select cable size to keep voltage drop ≤ 3% at pump full-load current over total drop length.
Use heat-shrink / cold-shrink jointing kits for field splices; never use insulation tape alone in submerged service.
