EPR/CSPE Cable Application
EPR/CSPE Cable is used in cathodic protection systems for buried structures as anode and DC feeder cables. Primary applications include pipelines, storage tanks, well casings, metal structures, and vessels.
- Anode Collector Cable: Connects the rectifier’s DC positive output to the anode ground bed (main anode).
- Negative Return Cable: Connects the protected structure (e.g., pipeline) back to the rectifier’s negative terminal.
- Interconnect Cable: Jumpers used to connect pipeline sections or other structures, ensuring electrical continuity.

Why EPR/CSPE Cable is the Ideal Choice for Cathodic Protection
Cathodic protection systems prevent corrosion in buried or submerged metal structures such as pipelines, tank bottoms, and ship hulls. The cables used in these systems face unique challenges:
- Harsh Environments: Directly buried in soil that may be corrosive, damp, and contain various chemicals.
- Mechanical stress: During installation, cables must traverse pipelines or trenches, often crossing sharp rocks.
- Long-term reliability: Cathodic protection systems must operate continuously for decades with minimal maintenance. Cable failure can cause costly losses and accelerate corrosion.
- Electrical requirements: Continuous transmission of direct current (often at high amperage) is required from rectifiers to anodes.
EPR/CSPE Cable Advantages
- Durability: Resistant to abrasion, crushing, and impact.
- Chemical Resistance: Suitable for contaminated soil and industrial environments.
- Weather Resistance: Can be stored on-site and installed under various weather conditions without degradation.
- Flexibility: Easier to handle and install compared to stiffer cables like XLPE.
- Long Service Life: EPR and CSPE material properties ensure extended operational longevity, matching the design lifespan of CP systems.
