This #10 AWG HMWPE Cathodic Protection Cable is a specialized single-conductor wire designed for use in cathodic protection systems as anode leads, test leads, or monitoring wires. Built to withstand the harsh conditions of direct burial or submersion, it provides a reliable, chemical-resistant path for current in both sacrificial and impressed current systems.
In the world of corrosion control, standard electrical wire is insufficient. The High Molecular Weight Polyethylene (HMWPE) insulation on this #10 AWG conductor is specifically engineered to resist the corrosive gases (such as chlorine and hydrogen) and moisture that are common in ground bed installations. It is a preferred size for test stations and smaller anode connections where flexibility and durability are equally important.
Chemical & Gas Shield: The HMWPE jacket provides a robust barrier against salts, moisture, and the electrolytic gases generated during the protection process.
Mechanical Toughness: Known for its high resistance to abrasion, crushing, and environmental stress cracking, allowing for direct burial without the need for conduit in most applications.
Direct Burial & Submergence: Rated for performance in wet locations, including deep-well ground beds and marine environments.
Reliable Conductivity: Manufactured with soft-drawn, stranded bare copper to ensure efficient current distribution and easy termination in test boxes or rectifiers.
Conductor Size: #10 AWG
Conductor Material: Stranded Bare Copper
Insulation Material: High Molecular Weight Polyethylene (HMWPE)
Voltage Rating: 600V
Temperature Rating: 75°C (167°F)
Amp Rating: 35 Amps (@ 75°C)
Standard Color: Black (UV Resistant)
Approvals: ASTM D-1248, ICEA S-95-658
Cathodic Protection Test Leads: The standard size for wiring test stations to monitor pipeline-to-soil potential.
Anode Lead Wire: Used to connect individual sacrificial anodes (magnesium or zinc) to the structure being protected.
Reference Electrode Wiring: Ideal for connecting permanent reference cells to monitoring equipment or rectifiers.
Negative Return Leads: Used in smaller-scale ICCP systems for the negative return to the structure.
Technical Note: While #10 AWG is rugged, it is important to ensure proper burial depth to avoid damage from surface activity. Any nick or scratch in the HMWPE jacket will allow the copper conductor to corrode rapidly once the system is energized. For environments with high concentrations of chlorine or hydrocarbons, a dual-insulated construction (HALAR/HMWPE) is recommended.

#10 AWG is a "heavy-duty" monitoring wire. While #14 and #12 are standard for basic sensors, #10 AWG is used when the test leads must span very long distances or when they are installed in harsh environments where maximum physical durability is required. It is also the go-to gauge for sacrificial anode leads for larger underground storage tanks (USTs) and shorter pipeline segments.
The shift to #10 is usually about Voltage Drop and Survivability.
Yes. In Impressed Current Cathodic Protection (ICCP), #10 AWG is frequently used for the "sensing" side of the rectifier. It allows the rectifier to get an extremely accurate, low-resistance reading of the structure’s protection levels, which is critical for the automated adjustment of the current output.
Absolutely. The High Molecular Weight Polyethylene (HMWPE) insulation is designed for both direct burial and water submersion. It is highly resistant to the salt, moisture, and chlorine gas often found in marine cathodic protection setups for piers, docks, and offshore platforms.
For cathodic protection applications, #10 AWG is typically rated for approximately 35 Amps @ 75°C, depending on the burial depth and soil temperature. However, in CP design, installers rarely push cables to their maximum ampacity. Instead, they size them to minimize resistance—if you are running high current over a long distance, you may want to jump to #8 or #6 AWG to ensure the system remains efficient.
Standard THHN wire uses a PVC jacket with a thin nylon skin, which is susceptible to "osmotic blistering" and chemical breakdown when buried. HMWPE is a much thicker, mono-layer insulation that acts as a true chemical shield. Because the cable is part of a circuit designed to prevent corrosion, any breach in the insulation would cause the copper wire to become the "sacrificial" part of the circuit, leading to a rapid failure of the monitoring system.
