Submersible Pump Cables

Submersible pump cables deliver dependable power to pumps operating underwater and in wet locations. Built to handle constant immersion, these cables resist moisture, minerals, oil, abrasion, and mechanical stress while maintaining flexibility for long well drops and tight conduit runs. Whether you need well pump wire for a deep borehole, a sump pump, or an irrigation system, quality submersible pump cable keeps motors running efficiently and safely.

Most constructions use high-conductivity copper or tinned copper to fight corrosion, paired with robust insulation such as XLPE or PE and a tough PVC outer jacket. Look for 600V ratings, UL/CSA listings, direct-burial approval, sunlight resistance, and potable-water certifications where required. Flat pump cable simplifies well installations alongside drop pipe, while round cable suits conduit pulls and applications needing added jacket protection.

Choose the correct conductor count for your pump: 2-wire with ground (2C + G) for many setups, or 3-wire with ground (3C + G) for systems using an external control box. Common sizes range from 14 AWG to 8 AWG; select gauge based on horsepower, voltage, and total run length to reduce voltage drop and heat. Color-coded conductors aid fast, accurate terminations.

Selection tips:
- Match cable ratings to environment: water chemistry, temperature, and chemical exposure.
- Size by amperage and distance; use a voltage-drop calculator for deep wells.
- Pick flat or round construction based on well geometry and installation method.
- Use waterproof splice kits (heat-shrink, adhesive-lined) and proper strain relief.
- Verify compliance with NEC, local code, and pump manufacturer guidelines.

Typical uses include residential wells, agricultural irrigation, livestock waterers, wastewater lift stations, fountains, and mining dewatering. The right submersible pump cable improves startup reliability, reduces service calls, and extends motor life. Explore options like tinned copper conductors, abrasion-resistant jackets, and pre-made splice kits to streamline installation and deliver long-lasting power to your deep well or sump pump.
