Parameters:
|
Environment (anode maximum operating current density) |
Current output/meter 1.5mm dia wire |
Current output/m 3.0mm dia wire |
|
In carbonaceous backfill (current density of 50 A/m²) |
0.25 A/m |
0.5 A/m |
|
In petroleum coke backfill (current density of 100 A/m²) |
0.5 A/m |
1.0 A/m |
|
In fresh water (current density of 100 A/m²) |
0.5 A/m |
1.0 A/m |
|
In seawater (current density of 600 A/m²) |
3.0 A/m |
6.0 A/m |
Design life: 20 years + when operating at an anode current density as above
Anode life can be extended up to 30 years or more by increasing the thickness of the MMO coating
