The Definitive Guide to Submersible Pump Cable: High-Performance Solutions for Well Systems

Electric Submersible Water Pump Cable for Submersible
Looking for the right well pump wire for your installation? You're in the right place. Our submersible pump cable is engineered for superior, long-lasting performance in the most demanding wet and direct-burial environments. Ideal for powering submersible well pumps, this cable is your reliable partner for residential, agricultural, and industrial water systems.
We don't just sell wire; we provide the correct, reliable solution to power your pump, ensuring years of trouble-free operation.
Why Our Submersible Pump Cable Stands Out
We build our submersible pump wire to exceed industry standards, giving you peace of mind with every installation.
- Premium Materials: Features high-quality stranded copper conductors for exceptional conductivity and flexibility, making installation in deep wells easier.
- Built for Harsh Environments: Our robust waterproof PVC / PE jacket offers superior resistance to moisture, chemicals, and abrasion. The double-insulated design provides an extra layer of protection for reliable performance in underground or underwater conditions.
- Certified Reliability: Our cable is UL Listed for direct burial in wet locations, a critical certification that guarantees it meets strict safety and performance standards. This rating confirms the cable is robust enough for permanent underground and underwater use without additional conduit.
- Wide Availability: Available in all common sizes like 12/2, 12/3, 10/2, 10/3, and other sizes such as 8/2, 8/3, and 6/3 upon request.

Frequently Asked Questions (FAQ)
Q1: What's the best way to determine the correct wire size for my pump? A: You must consider the pump's horsepower (HP), voltage, and the total distance from the power source to the pump motor. For a precise recommendation, use our free online Well Pump Wire Size Calculator or refer to the NEC table for a proper sizing.
Q2: Is this cable suitable for use with a control box? A: Yes. Our 3-wire submersible pump cables are specifically designed for systems that require an external control box. This setup is common for deep well pumps and larger HP motors.
Q3: Can I bury submersible pump wire directly underground? A: Yes. Our cables are UL listed for direct burial in wet environments. This rating guarantees the cable is robust enough to be buried without additional conduit, as long as you follow the National Electrical Code (NEC) and local regulations.
