0.6/1kV Flat S1BNH2-F Submersible Pump Rubber Cable 4G16mm
Falt S1BNH2-F Cable is a tough rubber unscreened 0.6/1kV cable for installation inside or outside in dry, damp or wet environments and in hazardous environments (subject to local regulations). It can be immersed in fresh and salt water to a depth of 300 meters: for flexible power supplies, suitable for submersible motors and pumps. The synthetic rubber compound is ozone, UV, sunlight and weather resistant.
Main Applications
- Submersible pumps: Water wells, drinking water supply, sewage treatment, wastewater pumps.

- Leisure & fountains: Swimming pool lights/filters, fountains, aquariums.
- Industrial: Cooling water systems, mines dewatering, process water, humid factories.
- Building & public: Elevator wiring, tunnels, basements, fire‑safe areas.
What’s the S1BNH2-F Submersible Cable?
S1BNH2-F is a type European construction & fire safety standards, widely used for fixed and mobile electrical connections in industrial, building and public facilities, S1BNH2‑F is a flat, unscreened, halogen‑free, low‑smoke, flame‑retardant flexible rubber cable for 0.6/1 kV service, designed for permanent submersion and mobile/heavy‑duty use.
S1: Low smoke emission classification (low fume, low toxicity when burning)
B: Flame retardant grade
NH2: Non-halogen fire-resistant category 2; zero halogen, no corrosive gas release during combustion
F: Flexible construction (stranded flexible conductor, for frequent bending & movement).
