- SAN-EARTH electrode resistance is 60-70% lower than bare copper counterpoise wire.
- Installation costs are similar.
- Resistance of the five meter SAN- EARTH electrode is the same as the twenty-meter long bare copper wire.
- Ideal contact with the surrounding soil is achieved because SAN-EARTH conforms to the shape of the trench.
- The effective surface area of the SAN-EARTH grounding electrode is about 25 times larger than the counterpoise wire.
