Cathodic protection cable from Performance Wire and Cable is suitable for direct burial applications, such as pipelines, storage tanks, pilings, well casings, cables, marine crafts, along with any other burial or water-submerged metallic structures. Our HMWPE cathodic protection cable utilizes stranded copper conductors that are insulated with a high molecular weight polyethylene (HMWPE) compound that provides strong resistance to abrasion, crushing, chemicals, oil, moisture, and other elements. We use all-natural materials in the production of our pipeline cathodic protection cables. With a copper conductor rated for 600 volts, our HMWPE wire is available in sizes 14 AWG through 1/0 AWG.

HMWPE FAQs
What is HMWPE Cable?
HMWPE stands for High Molecular Weight Polyethylene. It is a single, stranded bare copper conductor and polyethylene (PE) insulation. It is sunlight, abrasion, moisture, and chemical-resistant.
What are the most common applications for HMWPE Wire?
High Molecular Weight Polyethylene (HMWPE) wire finds frequent use in various applications such as pipelines, storage tanks, pilings, well casings, cables, marine crafts, and any other metallic structures intended for burial or water submersion.
What is HMWPE insulation?
High Molecular Weight Polyethylene (HMWPE) insulation refers to our black compound made from high-molecular-weight polyethylene, offering exceptional resistance to abrasion, crushing, chemicals, oils, and moisture. Additionally, it boasts outstanding dielectric strength.
What applications is HMWPE cable used for?
HMWPE cable is used for direct burial applications, such as pipelines, storage tanks, pilings, well casings, cables, marine crafts, along with any other burial or water submerged metallic structures. HMWPE cables are used in water towers, parking garages, oil rigs, gas lines, amusement parks and so much more.
What is the difference between HMWPE vs. HDPE?
Both HDPE and HMWPE are thermoplastics. HDPE offers excellent chemical resistance but it is more difficult to computer numerical control (CNC) engineer into machine components. HDPE has a working temperature range: -65 to +80°C. HMWPE is widely used as wear parts and abrasion resistant plastic components in the conveyor and materials handling industry. HMWPE has a wider working temperature range: -120 to +80°C. HMWPE offers better chemical resistance and low moisture absorption than HDPE.
