Deep earthing system
Benefits
Elpress systems for deep earthing have
many advantages:
• The ground line has joints risk
of contact failure.
This combination metal both stabilises
and equalises its surroundings.
• When copper line used, the extension
rods act sacrificial anodes and provi-
de good protection against corrosion.g.
• Full control over the line and tip main-

resistance can continually measured

• Rod length 800 for best ergono-
