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.
