#4 AWG HMWPE Cathodic Protection Cable | 600V Direct Burial

This #4 AWG HMWPE Cathodic Protection Cable is a high-durability, single-conductor wire engineered specifically for impressed current cathodic protection (ICCP) systems. Designed for direct burial or submersion, it provides the essential electrical path to prevent corrosion on critical infrastructure such as pipelines, storage tanks, and marine pilings.

Why Choose #4 AWG HMWPE Cable?

Cathodic protection environments are notoriously harsh due to the presence of corrosive gases, moisture, and varying soil chemistry. High Molecular Weight Polyethylene (HMWPE) is the industry-standard insulation for these applications because it offers a unique combination of chemical stability and mechanical toughness that standard power cables lack.

• Chemical & Moisture Barrier: The HMWPE jacket is specifically designed to resist degradation from chlorine, hydrogen, and other gases produced during the electrolytic process at the anode bed.

• Rugged Mechanical Protection: Features elite resistance to abrasion, crushing, and environmental stress cracking, ensuring the cable remains intact during backfilling and throughout the life of the system.

• Direct Burial & Submerged Rating: Fully rated for direct burial in soil and for use in fresh, brackish, or salt water.

• High Conductivity: Manufactured with soft-drawn, stranded bare copper to ensure efficient current distribution and reliable protection for metallic structures.

Common Applications

• Pipeline Infrastructure: Ideal for anode lead and feeder cables for buried oil, gas, and water transmission lines.

• Storage Tank Protection: Used to connect rectifiers to sacrificial or impressed current anodes for underground and above-ground tanks.

• Marine & Offshore: Protects steel pilings, bulkheads, and underwater structures in saltwater environments.

• Ground Beds: Critical for wiring within deep-well or surface-ground-bed installations where chemical resistance is paramount.

Technical Note: Maintaining the integrity of the insulation is critical; any breach in the HMWPE jacket allows the copper conductor to become an accidental anode, leading to rapid wire corrosion and system failure. For environments with high concentrations of chlorine gas or hydrocarbons, consider a dual-insulated construction (HALAR/HMWPE).
