This 4/0 AWG HMWPE Cathodic Protection Cable is a heavy-duty, single-conductor wire specifically designed for use in impressed current cathodic protection systems. It is engineered to perform in the most demanding environments, including direct burial in corrosive soils or submersion in fresh, brackish, or salt water.
In cathodic protection, the cable is the lifeline of the system. Standard insulation often fails when exposed to the electrolytic activity and corrosive gases (like chlorine) generated at anode sites. The High Molecular Weight Polyethylene (HMWPE) used in this cable is a specialized "thermoset-like" material that offers superior resistance to environmental stress cracking and chemical degradation.
Superior Shielding: The HMWPE jacket provides an outstanding barrier against moisture and the aggressive chemicals found in industrial ground beds.
Mechanical Integrity: Known for its high "cut-through" resistance, this cable stands up to the mechanical rigors of installation and backfilling without requiring conduit.
Optimized Conductivity: Manufactured with soft-drawn, stranded bare copper to ensure efficient current distribution over long distances.
UV and Weather Resistant: While primarily used for burial, the black jacket is stabilized for resistance to ultraviolet light.
Conductor Size: 4/0 AWG
Conductor Material: Stranded Bare Copper
Insulation Material: High Molecular Weight Polyethylene (HMWPE)
Voltage Rating: 600V
Temperature Rating: 75°C (167°F)
Amp Rating: 230 Amps (@ 75°C)
Standard Color: Black
Approvals: ASTM D-1248, ICEA S-95-658
Pipeline Feeders: Used for both positive and negative leads in pipeline corrosion control systems.
Storage Tanks: Ideal for connecting rectifiers to anode arrays for large underground or above-ground tank bottoms.
Marine Structures: Used to protect pier pilings, offshore platforms, and bulkheads from saltwater corrosion.
Deep Well Anodes: Designed to withstand the submerged conditions of deep-well ground bed installations.
Technical Note: To prevent premature system failure, it is critical to ensure the jacket is not damaged during installation. Any breach in the insulation allows the copper conductor to become an accidental anode, leading to rapid wire corrosion. For high-chlorine or hydrocarbon environments, consider upgrading to a dual-insulated HALAR/HMWPE construction.

4/0 AWG (Four-Ought) is the ultimate Main Positive Feeder and Negative Return Header. It is used in large-scale Impressed Current Cathodic Protection (ICCP) systems where massive amounts of current must be moved across vast distances. This size is standard for protecting interstate oil and gas pipelines, municipal water systems, and large-scale tank farms.
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 decision to use 4/0 Cathodic Protection Cable is almost always about eliminating resistance. In very large systems, even 2/0 or 3/0 wire can suffer from "Line Loss." Using 4/0 ensures that the rectifier doesn't have to work as hard to push current through the wire, ensuring that the furthest structure in your system still receives the critical -850mV protective potential.
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.
Yes. Our 4/0 HMWPE is engineered for Direct Burial in the most saturated and aggressive soils. The High Molecular Weight Polyethylene jacket is non-porous and exceptionally resistant to moisture ingress and "osmotic blistering." It is frequently used in coastal regions and wetlands where the soil is chronically wet and chemically active.
In a typical direct burial environment, 4/0 is rated for approximately 230 Amps @ 75°C. However, in the CP industry, we use this size for electrical efficiency. Operating a 4/0 cable at lower current levels ensures the system runs cool, which protects the integrity of the insulation and maximizes the lifespan of your entire corrosion prevention system.
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.
4/0 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.
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.
