Deep Well Grounding System
High Silicon Cast Iron Anode
Application:
High Silicon Cast Iron Anodes have been used for many decades to protect buried and submerged structures
from corrosion. This anodes can operate effectively in a variety of electrolytes, from soil and freshwater to
brackish and salt water environments. Under normal conditions, a thin film of silicon dioxide will develop on its
surface, this film protects the anodes from metal pitting and makes them ideally suited for deep groundbed
application.
Features and Benefits:
High Silicon Cast Iron grounding rods offer a technologically superior alternative to copper grounding that
overcomes the performance dampening effect that it can have on cathodic protection systems.
☆Mitigate harmful and expensive corrosion couples between bare copper electrical
groundings and vulnerable underground steel piping and structures.
☆Reduce installation and operating costs for cathodic protection.
☆Overcome copper grounding effects that seriously compromise monitoring and control of Cathodic Protection
for associated piping and structures.
☆Withstand corrosive environments that consume copper groundings.
