This #6 AWG HMWPE Cathodic Protection Cable is a high-performance single-conductor wire engineered specifically for impressed current cathodic protection (ICCP) systems. Designed to withstand the unique electrochemical stresses of buried and submerged environments, it provides a rugged, reliable link between rectifiers and anodes to prevent corrosion on critical metallic infrastructure.
In cathodic protection applications, the cable must act as a primary barrier against aggressive chemicals and the corrosive gases (such as chlorine and hydrogen) generated by the protection process itself. The High Molecular Weight Polyethylene (HMWPE) insulation is a specialized material that provides significantly more mechanical toughness and chemical stability than standard PVC power cables.
Electrochemical Resilience: The HMWPE jacket is designed to resist degradation from the electrolytic gases produced at the anode bed that would typically destroy standard wire insulation.
Tough Insulation: Offers elite resistance to abrasion, crushing, and environmental stress cracking, which is essential for maintaining integrity during direct burial and backfilling.
Direct Burial & Submerged Rating: Suitable for installation directly in the earth or for submersion in fresh, brackish, or salt water.
High-Purity Copper: Utilizes stranded bare copper for maximum electrical efficiency, ensuring minimal power loss over long circuit runs.
Conductor Size: #6 AWG
Conductor Material: Stranded Bare Copper
Insulation Material: High Molecular Weight Polyethylene (HMWPE)
Voltage Rating: 600V
Temperature Rating: 75°C (167°F)
Amp Rating: 65 Amps (@ 75°C)
Standard Color: Black (UV Resistant)
Approvals: ASTM D-1248, ICEA S-95-658
Pipeline Infrastructure: Primary feeder and anode lead wire for oil, gas, and water pipelines.
Storage Tank Bottoms: Connecting rectifiers to anode arrays for underground and above-ground storage tanks.
Marine Protection: Used for cathodic protection of steel pilings, piers, bulkheads, and other coastal infrastructure.
Anode Ground Beds: Ideal for deep-well and surface ground beds where chemical resistance and reliability are paramount.
Technical Note: Always verify the integrity of the insulation before burial. Even minor nicks in the HMWPE jacket can cause the copper conductor to corrode rapidly once energized, leading to total system failure. For environments with high concentrations of chlorine or hydrocarbons, a dual-insulated construction (HALAR/HMWPE) is often recommended.

#6 AWG is a heavy-duty "feeder" cable. It is typically used as a header cable that connects multiple smaller anode leads together before heading back to the rectifier. It is also the preferred size for larger impressed current anodes and for providing protection to significant lengths of mid-sized utility piping.
The jump to #6 is almost always about Current Capacity and Distance. As your system grows, the amount of protective current (amperage) increases. Using #6 AWG allows you to push more current over longer distances with less heat and less voltage drop. If your rectifier is located far from your anode bed, #6 helps ensure the "driving voltage" remains high enough to protect the structure.
NOTE: Cathodic Protection systems are highly site-specific. Before selecting your cable gauge, we strongly recommend consulting with a NACE-certified Corrosion Engineer or a licensed CP installer to verify your voltage drop calculations and soil resistivity requirements.
Yes. The High Molecular Weight Polyethylene (HMWPE) insulation is exceptionally resistant to salt water, moisture, and the chemicals found in marine silt. It is frequently used to protect sheet piling, offshore platforms, and submerged dock structures.
Our #6 HMWPE is Sunlight Resistant (UV Rated). This is important because while most of the cable will be buried, sections often emerge from the ground to enter a rectifier or a junction box. Standard buried wire would crack under UV exposure, but HMWPE remains stable and flexible, preventing the jacket from "stress cracking" over time.
In a typical direct burial environment, #6 AWG is rated for approximately 65 Amps @ 75°C. However, to ensure a 25+ year lifespan for the system, engineers usually design the circuit to run at a fraction of that capacity. This keeps the cable cool and prevents "insulation migration," which can occur if a cable is chronically overloaded.
NOTE: Cathodic Protection systems are highly site-specific. Before selecting your cable gauge, we strongly recommend consulting with a NACE-certified Corrosion Engineer or a licensed CP installer to verify your voltage drop calculations and soil resistivity requirements.
While #6 has a very thick insulation layer, no cable is completely "rock-proof." In extremely rocky or aggressive soils, we recommend a sand-padding installation or a "Dual-Insulated" cable. However, for most standard pipeline and tank farm applications, #6 HMWPE provides excellent mechanical toughness and abrasion resistance.
Cathodic Protection cable is a specialized electrical conductor used to prevent corrosion in buried or submerged metallic structures, such as pipelines, storage tanks, and pier pilings. It connects the structure to an anode system, carrying the direct current (DC) necessary to neutralize the electrochemical process that causes rust and decay.
HMWPE stands for High Molecular Weight Polyethylene. It is the "outer shell" of most CP cables. It is used because it is incredibly tough, moisture-resistant, and has high dielectric strength, allowing the cable to be buried directly in a variety of soil types without a conduit.
