This #2 AWG HMWPE Cathodic Protection Cable is a rugged, single-conductor wire specifically designed for impressed current cathodic protection (ICCP) systems. It serves as the primary connection between rectifiers and anodes, engineered to survive direct burial in aggressive soil or submersion in fresh, brackish, or salt water.
Cathodic protection systems create a unique electrochemical environment where standard insulation materials often fail. High Molecular Weight Polyethylene (HMWPE) provides a specialized "shield" against the corrosive gases (such as chlorine and hydrogen) and moisture that are common in ground bed installations.
Chemical & Gas Resilience: The HMWPE jacket is highly resistant to acids, alkalis, and the electrolytic gases generated at the anode site.
Mechanical Toughness: Known for its superior "cut-through" and abrasion resistance, this cable is built to handle the mechanical stresses of direct burial and soil settling without the need for conduit.
Direct Burial & Submergence: Rated for performance in wet locations, including deep-well ground beds and marine applications.
Optimized Electrical Flow: Manufactured with soft-drawn, stranded bare copper to ensure maximum conductivity and reliable current discharge.
Conductor Size: #2 AWG
Conductor Material: Stranded Bare Copper
Insulation Material: High Molecular Weight Polyethylene (HMWPE)
Voltage Rating: 600V
Temperature Rating: 75°C (167°F)
Amp Rating: 115 Amps (@ 75°C)
Standard Color: Black (UV Resistant)
Approvals: ASTM D-1248, ICEA S-95-658
Pipeline Protection: Used for anode leads and feeder cables for oil, gas, and water transmission pipelines.
Storage Tank Bottoms: Ideal for connecting rectifiers to sacrificial or impressed current anodes for underground and above-ground tanks.
Marine & Coastal Works: Protection of steel sheet piles, bulkheads, and jetty structures.
Anode Ground Beds: The industry standard for wiring within deep-well and surface-ground-bed installations.
Technical Note: Because the system relies on the integrity of the insulation, any breach in the HMWPE jacket will allow the copper conductor to corrode rapidly. Always inspect the cable for nicks or scratches before burial. For environments with high concentrations of chlorine or hydrocarbons, a dual-insulated construction (HALAR/HMWPE) is recommended for enhanced protection.

#2 AWG is a high-capacity Main Trunk Line or Feeder Cable. It is typically used in large-scale Impressed Current Cathodic Protection (ICCP) systems to connect the rectifier to multiple anode groundbeds. It is also often a preferred size for the main negative return on large-diameter pipelines and the bottom of massive storage tanks where current demands are significant.
The decision to move to #2 AWG is usually driven by current density and long-distance voltage drop. If your system needs to deliver high amperage over a long distance (such as across a large tank farm or along a highway pipeline stretch), the #2 conductor provides the lower resistance necessary to ensure the structure reaches the required -850mV protective 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, but with a caveat. While #2 HMWPE is extremely rugged and chemical-resistant, deep-well environments often have high concentrations of chlorine gas. For standard soil or fresh water, #2 HMWPE is the gold standard. However, if the well is brackish or high-salinity, many engineers prefer a Dual-Insulated cable (HALAR/HMWPE) for maximum long-term survivability.
Absolutely. Our #2 HMWPE is designed for the most aggressive environments. The High Molecular Weight Polyethylene insulation is non-porous and resists the "osmotic blistering" that causes standard wire to fail in wet or submerged conditions. It is frequently used for protecting offshore platforms, sheet piling, and submerged dock infrastructure.
In a typical direct burial environment, #2 AWG is rated for approximately 115 Amps @ 75°C. In the cathodic protection industry, contractors often intentionally "oversize" to #2 to ensure the system remains highly efficient. Running at a fraction of the max ampacity prevents the insulation from heating up, which can extend the service life of the cable 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.
Yes. Because #2 is a much thicker conductor, care must be taken during installation to avoid "over-bending," which can stress the HMWPE insulation. Always follow industry standards for the minimum bending radius—especially when the cable is exiting a trench and entering a conduit riser or the bottom of a rectifier cabinet.
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.
