Outback FMR3G2.5 3 Core 2.5 mm² Heavy-Duty Submersible Solar Pump Cable — Per Metre

The Outback FMR3G2.5 Submersible Solar Pump Cable is a heavy-duty, rubber-insulated 3-core power cable designed specifically for submersible solar bore pumps and water transfer systems. Built to withstand constant immersion, harsh outdoor conditions, and mechanical stress, it delivers reliable power transmission in demanding rural and remote installations.

Featuring 2.5 mm² tinned copper conductors and a flexible rubber construction, this cable is ideal for DC and AC solar pump systems where durability, flexibility, and voltage stability are critical.

DESIGNED FOR SUBMERSIBLE PUMPS

This cable is manufactured to 0.6/1 kV rating and is suitable for continuous submersion up to 200 m, making it ideal for bore pump drop cables and underwater connections. The rubber insulation and outer sheath provide excellent resistance to:

• Water (fresh, salt, and contaminated)
• UV and sunlight
• Oils, abrasion, and weather exposure
• These characteristics make it far more reliable than standard PVC cables in pump installations

VOLTAGE DROP & DISTANCE GUIDANCE

Based on motor current and voltage-drop calculations commonly used for submersible pumps, the FMR3G2.5 (2.5 mm²)cable is suitable for runs of up to ~80 m with a 1.0 kW pump, keeping voltage drop within acceptable limits.

✔ Ideal for most 3" solar bore pump installations
⚠ Longer runs or higher-power pumps may require larger cable sizes
