In cathodic protection (CP) of buried metallic structures such as well casings, pipelines, and storage tank bottoms, anode groundbed performance directly determines protection effectiveness. NW HENGYI METAL supplies MMO tubular string anodes designed specifically for deep well CP in soil applications — combining high current output with long service life.

Key Advantages
High Current Output — Each anode delivers up to 8 Amps. The 25mm × 1000mm tubular geometry offers an excellent surface-area-to-weight ratio, ensuring high electrochemical efficiency in space-limited deep well groundbeds.
Reliable Encapsulation — The anode-to-cable connection is the most vulnerable point in deep well CP. NW HENGYI METAL applies a high-quality encapsulation method to ensure reliable electrical insulation, moisture and chemical resistance, mechanical robustness, and stable long-term performance.
Durable Cable Construction — 25mm² single core Cu/XLPE/PVC cable: copper conductor for stable conductivity, XLPE insulation for high dielectric strength, and PVC outer sheath for resistance to soil chemicals — ensuring reliable power delivery.
Uniform Current Distribution — 3-meter anode spacing and 25-meter total string length, with 6 centralizers to keep the string centered, preventing over-protection, under-protection, and installation damage.
Typical Applications
Deep well CP of well casings
Buried pipelines and mains
Storage tank bottoms
Underground metallic structures
