What Are Impressed-Current Anodes?

Impressed-current anodes are components of cathodic protection systems that use an external power source to impress current onto a structure, counteracting the natural corrosion process. Unlike sacrificial anodes, impressed-current systems can protect larger structures and provide adjustable levels of protection based on environmental conditions.

Key Benefits
  • Extended service life (15-30+ years)
  • Higher current output capability
  • Adaptable protection levels
  • Effective for large structures
  • Suitable for high-resistivity environments
  • Remote monitoring capabilities
Common Applications
  • Pipeline protection (oil, gas, water)
  • Marine structures and vessels
  • Underground storage tanks
  • Reinforced concrete structures
  • Industrial water systems
  • Well casings and offshore platforms

Our Impressed-Current Anode Products

MMO Anode Wire (CPW)

CerAnode’s CPW MMO Mixed-Metal-Oxide Anode Wire is a flexible, high-performance linear anode for impressed-current cathodic protection (ICCP). Engineered with a thin noble-metal-oxide coating on a core wire, it provides a durable, low-consumption solution for uniform current distribution.
