This 3/0 AWG HMWPE Cathodic Protection Cable is a high-performance, single-conductor wire engineered specifically for impressed current cathodic protection (ICCP) systems. Built to withstand the electrochemical challenges of buried or submerged environments, it provides a reliable, high-conductivity path to prevent corrosion on critical metallic infrastructure.
In cathodic protection applications, the cable must act as a barrier against aggressive chemicals and the corrosive gases 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 or XLPE power cables.
Electrochemical Resilience: The HMWPE jacket is designed to resist degradation from chlorine, hydrogen, and other gases produced at the anode bed.
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: 3/0 AWG
Conductor Material: Stranded Bare Copper
Insulation Material: High Molecular Weight Polyethylene (HMWPE)
Voltage Rating: 600V
Temperature Rating: 75°C (167°F)
Amp Rating: 200 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 large-scale 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 high current and chemical resistance are required.
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, leading to system failure. For environments with high concentrations of chlorine or hydrocarbons, consider a dual-insulated construction (HALAR/HMWPE).

3/0 (Three-Ought) serves as a high-capacity Main Trunk Line. It is primarily used as the positive feeder to connect a rectifier to a large anode groundbed or as the primary negative return for massive infrastructure, such as utility-scale storage tanks, power plant foundations, and interstate pipelines.
In the world of corrosion engineering, the jump to 3/0 AWG is a strategic decision to reduce Line Resistance. If your project involves high-amperage current traveling over significant distances, 3/0 AWG provides the massive copper cross-section needed to minimize voltage drop. This ensures that the structure at the end of the line receives the full protective "potential" required to stop corrosion.
TIP: 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.
Absolutely. The High Molecular Weight Polyethylene (HMWPE) jacket is specifically designed for both direct burial and water submersion. It is a non-porous, chemically inert shield that resists the salt, moisture, and "osmotic blistering" that typically causes standard industrial wires to fail in submerged marine or damp soil environments.
While 3/0 AWG is rated for approximately 200 Amps @ 75°C in a typical direct burial environment, it is rarely pushed to this limit in CP applications. Engineers specify 3/0 to ensure the circuit stays "cool" and highly efficient. This low-resistance approach reduces the workload on your rectifier and prevents long-term heat degradation of the insulation.
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 3/0 CP Cable is a heavy, rigid cable, it requires a larger minimum bending radius than smaller gauges. Installers should use mechanical pulling equipment carefully and ensure the trench is padded with clean sand. Any "holiday" (nick) in the insulation caused by sharp rocks during backfill can lead to the copper wire itself becoming a sacrificial anode, eventually causing a total system failure.
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.
