This 2/0 AWG HMWPE Cathodic Protection Cable is a heavy-duty, single-conductor wire engineered specifically for impressed current cathodic protection (ICCP) systems. Designed for extreme durability, it is built to survive direct burial in aggressive soil conditions or submersion in fresh, brackish, or salt water, acting as the critical power link to prevent corrosion on buried metallic structures.
In cathodic protection applications, the cable must withstand constant exposure to corrosive gases (like chlorine and hydrogen) and moisture. High Molecular Weight Polyethylene (HMWPE) is the industry standard for these environments because it offers far superior mechanical toughness and chemical stability compared to standard insulation.
Chemical & Gas Shield: The HMWPE jacket provides a specialized barrier against the electrolytic gases generated at the anode bed that would typically degrade standard wire.
Rugged Mechanical Protection: Features exceptional resistance to abrasion, crushing, and environmental stress cracking, allowing for direct burial without the need for conduit.
Direct Burial & Submergence: Specifically rated for "wet" applications, including deep-well ground beds and marine environments.
High Conductivity: Manufactured with soft-drawn, stranded bare copper to ensure efficient current distribution with minimal voltage drop over long circuit runs.
Conductor Size: 2/0 AWG
Conductor Material: Stranded Bare Copper
Insulation Material: High Molecular Weight Polyethylene (HMWPE)
Voltage Rating: 600V
Temperature Rating: 75°C (167°F)
Amp Rating: 175 Amps (@ 75°C)
Standard Color: Black (UV Stabilized)
Approvals: ASTM D-1248, ICEA S-95-658
Pipeline Systems: Used for positive and negative leads in pipeline corrosion control for oil, gas, and water lines.
Storage Tanks: Ideal for connecting rectifiers to sacrificial or impressed current anodes for underground and above-ground storage tanks.
Marine & Coastal Infrastructure: Protection of steel pilings, bulkheads, and jetty structures.
Anode Ground Beds: The preferred conductor for wiring within deep-well and surface-ground-bed installations.
Technical Note: To ensure a long system life, ensure the insulation is not nicked during installation. Any breach in the HMWPE jacket can cause the copper conductor to corrode rapidly once energized. For environments with high concentrations of chlorine or hydrocarbons, a dual-insulated construction (HALAR/HMWPE) is recommended.

2/0 (Two-Ought) is a heavy-capacity Main Header Cable. It is typically utilized in extensive Impressed Current Cathodic Protection (ICCP) systems. Common uses include serving as the main positive feeder for large groundbeds or acting as the primary negative return for massive infrastructure like interstate gas pipelines, large-scale tank farms, and power plant intake structures.
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.
The jump to 2/0 is almost always dictated by Voltage Drop over extreme distances. In massive pipeline spreads, the distance between the rectifier and the structure can lead to significant signal loss. The 2/0 conductor provides the massive cross-sectional area needed to ensure that the protective current reaches the structure with enough "driving voltage" to maintain the required -850mV potential.
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. Our 2/0 HMWPE features an extra-thick layer of High Molecular Weight Polyethylene. This insulation is specifically engineered for direct burial in harsh, abrasive soils. It is highly resistant to "cut-through" damage and environmental stress cracking, which is critical during the heavy machinery backfilling process used for cables of this size.
Absolutely. It is the gold standard for marine pier and offshore platform protection. The non-porous HMWPE jacket is designed to be submerged indefinitely, resisting the salt, moisture, and "osmotic blistering" that typically destroys standard THHN or XHHW electrical wires in saltwater applications.
While 2/0 Cathodic Protection Cable has a standard ampacity rating of approximately 175 Amps @ 75°C in direct burial, it is chosen for its electrical efficiency. By using such a large conductor, you drastically reduce the heat generated within the cable. This ensures a 40+ year service life and allows the rectifier to operate at peak efficiency, saving on long-term energy costs.
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.
Due to its weight and rigidity, 2/0 AWG requires careful handling. It is vital to maintain the minimum bending radius to prevent "crow's footing" or stressing the HMWPE insulation. Additionally, when making high-amperage connections (such as exothermic welds or "Cadwelds"), ensure the insulation is trimmed cleanly and resealed with an approved moisture-proof kit to prevent copper corrosion at the splice point.
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.
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.
