This #1 AWG HMWPE Cathodic Protection Cable is a specialized single-conductor wire designed for impressed current cathodic protection (ICCP) systems. It is engineered to withstand the aggressive electrochemical environments found in direct burial or submerged applications, serving as a critical link for the protection of buried pipelines and metallic structures.
In cathodic protection, the cable insulation is the first line of defense against system failure. Standard electrical insulation can be compromised by the corrosive gases (such as chlorine and hydrogen) generated at the anode. High Molecular Weight Polyethylene (HMWPE) provides a superior chemical barrier and exceptional mechanical toughness.
Chemical & Gas Resistance: The HMWPE jacket is specifically formulated to resist degradation from salts, moisture, and the acidic or alkaline conditions common in ground beds.
Mechanical Integrity: Known for its high "cut-through" resistance and abrasion durability, this cable is designed to be buried directly in the earth without the protection of conduit.
Direct Burial & Submergence: Fully rated for use in soil and for submersion in fresh, brackish, or salt water.
High Conductivity: Constructed with soft-drawn, stranded bare copper to ensure efficient current distribution with a low voltage drop over long feeder runs.
Conductor Size: #1 AWG
Conductor Material: Stranded Bare Copper
Insulation Material: High Molecular Weight Polyethylene (HMWPE)
Voltage Rating: 600V
Temperature Rating: 75°C (167°F)
Amp Rating: 130 Amps (@ 75°C)
Standard Color: Black (UV Resistant)
Approvals: ASTM D-1248, ICEA S-95-658
Pipeline Infrastructure: Used as anode leads and positive/negative feeder cables for oil, gas, and water pipelines.
Storage Tank Bottoms: Ideal for connecting rectifiers to anodes for underground and above-ground storage tanks.
Marine Environments: Protection for steel sheet piles, bulkheads, and jetty structures.
Deep Well Ground Beds: Reliable performance when submerged in water and coke breeze within deep-well installations.
Technical Note: To prevent premature failure, it is vital to ensure the insulation is not damaged during the pull or backfill process. Any breach in the HMWPE jacket allows the copper conductor to become an accidental anode, leading to rapid corrosion at the site of the nick. For extreme chlorine or hydrocarbon environments, a dual-insulated construction (HALAR/HMWPE) is recommended.

#1 AWG is a heavy-duty Positive or Negative Feeder. It is typically utilized in large-scale industrial projects, such as power plant cooling systems or major oil and gas pipeline spreads. Because it sits between #2 and 1/0 AWG, it is often specified when an engineer needs a very precise balance of high ampacity and low resistance to ensure a large structure receives uniform current distribution.
In massive infrastructure projects, the distance from the power source (rectifier) to the anode bed can be over a mile. The #1 AWG conductor offers an extremely large copper cross-section that keeps line resistance at a minimum. This ensures that the voltage potential at the far end of the system is high enough to halt corrosion without over-working the rectifier.
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.
The insulation thickness is scaled to match the conductor size, providing a rugged, non-porous shield. This High Molecular Weight Polyethylene (HMWPE) is designed to withstand the harsh chemistry of "Impressed Current" systems, where the soil can become saturated with gases like chlorine and hydrogen. The jacket prevents these gases and soil moisture from reaching the copper, which would cause the cable itself to fail.
Yes. It is an excellent choice for submerged piling protection. Its weight and diameter provide the mechanical durability needed to survive tidal shifts and potential debris impact, while the HMWPE jacket resists the "osmotic blistering" and saltwater ingress that destroys standard electrical cables.
In standard direct burial conditions, #1 AWG is rated for approximately 135 Amps @ 75°C. However, CP systems are designed for longevity, not just capacity. By using #1 AWG, you ensure the cable remains cool and operates at a very low percentage of its total capacity, which can extend the system's operational life to 40+ years.
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.
Because of its large size and stiffness, #1 AWG has a larger minimum bending radius. Installers must take care when routing the cable into junction boxes or rectifier cabinets to avoid crimping or stressing the insulation. We recommend using large-radius sweeps and ensuring the trench is free of sharp rocks that could nick the heavy HMWPE jacket during backfilling.
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.
