This 1/0 AWG HMWPE Cathodic Protection Cable is a specialized single-conductor wire engineered for use in impressed current cathodic protection (ICCP) systems. Designed to withstand the unique electrochemical stresses of buried and submerged environments, it provides a rugged, high-conductivity link between rectifiers and anodes.
Standard insulation types often fail in cathodic protection environments due to the production of corrosive gases and varying soil pH. High Molecular Weight Polyethylene (HMWPE) is specifically formulated to provide maximum mechanical toughness and chemical stability, serving as a critical barrier for the copper conductor.
Chemical Barrier: The HMWPE jacket is highly resistant to chlorine, hydrogen, and other corrosive gases commonly generated at the anode bed.
Mechanical Durability: Known for its high "cut-through" and abrasion resistance, this cable is designed to survive the rigors of direct burial and the pressures of backfilling.
Direct Burial & Submerged Rating: Rated for direct burial in harsh soils and for use in fresh, brackish, or salt water.
Optimized Conductivity: Constructed with soft-drawn, stranded bare copper to ensure efficient current distribution and minimal voltage drop.
Conductor Size: 1/0 AWG
Conductor Material: Stranded Bare Copper
Insulation Material: High Molecular Weight Polyethylene (HMWPE)
Voltage Rating: 600V
Temperature Rating: 75°C (167°F)
Amp Rating: 150 Amps (@ 75°C)
Standard Color: Black (UV Resistant)
Approvals: ASTM D-1248, ICEA S-95-658
Transmission Pipelines: Essential for both positive and negative leads in pipeline corrosion control systems.
Storage Tank Protection: Used to connect rectifiers to anode arrays for large-scale underground and above-ground storage tanks.
Marine Infrastructure: Protects pier pilings, offshore platforms, and bulkheads from saltwater corrosion.
Ground Bed Feeds: Preferred for wiring in surface-ground-bed and deep-well anode installations.
Technical Note: To prevent premature system failure, the HMWPE jacket must remain intact. Any breach in the insulation allows the copper conductor to become an accidental anode, leading to rapid corrosion and circuit failure. For high-chlorine or hydrocarbon environments, a dual-insulated construction (HALAR/HMWPE) should be considered.

1/0 Cathodic Protection Cable is a heavy-duty Main Trunk Line or Feeder Header. It is designed to carry high-amperage current from the rectifier to large anode groundbeds. In massive systems, such as cross-country pipelines or large tank farms, it serves as the central "artery" that distributes power to multiple smaller #4 or #8 AWG branch circuits.
The transition to 1/0 Cathodic Protection Cable is driven by the need for extreme low resistance. As your system grows in physical size, the distance between the power source and the structure increases. 1/0 AWG offers a massive copper cross-section that minimizes Voltage Drop, ensuring that the "Driving Voltage" remains strong enough to push protective current to the furthest reaches of the buried 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. It is frequently used for marine pile and dock protection. Its large diameter and heavy HMWPE jacket provide the mechanical durability needed to withstand tidal forces and debris impact, while the High Molecular Weight Polyethylene insulation prevents saltwater from reaching the conductor and causing internal corrosion.
1/0 is a common choice for deep-well headers. However, if the well environment is high in chlorine or brine, engineers may specify a "Dual-Insulated" HALAR/HMWPE construction. For standard soil burial and most fresh or brackish water applications, this 1/0 HMWPE is the industry standard for durability and cost-efficiency.
In a typical direct burial configuration, 1/0 AWG is rated for approximately 150 Amps @ 75°C. In Cathodic Protection, we rarely push the cable to its thermal limit. Instead, we use the 1/0 gauge to ensure the system runs with maximum electrical efficiency, which helps extend the operational life of the rectifier and the cable itself 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.
1/0 is a stiff, heavy conductor. Care must be taken during installation to observe the minimum bending radius (typically 8 to 12 times the cable diameter). Over-bending or kinking the cable during a pull can stress the HMWPE insulation, creating microscopic "holidays" (nicks) that can lead to premature failure of the system.

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.
