8 length driven line
and rod, extension rod pushed into
the preceding rod.
• When copper line used, the extension
rods act sacrificial anodes and provi-
de good protection against corrosion. Because the earthing
resistance can continually measured
at the other end the line, one can stop
driving when suitable value reached
and the last extension rod then
withdrawn.
Radio base station application for
Elpress deep earthing systems. This means that the prac-
tical service life often longer than the
theoretical.
• Can used for different types line
e. The current
is thereby reduced and thus also the
corrosion.
• Rod length 800 for best ergono-
mics. An
AC load should theoretically counteract
the corrosion.
• Tip and leading rod are manufactured
for large area range; mm².
This combination metal both stabilises
and equalises its surroundings. other words, the lead
sheath has theoretical service life of
almost double. The electrode consists a
copper line that driven down sys-
tem consisting 0.8 long steel rods.
• Full control over the line and tip main-
tained and possible continuously
measure the earthing resistance.
• The overall cost complete earth
connection will lower than that
made conventional manner. The steel
rods act sacrificial anodes with rela-
tively high corrosion current against the
copper electrode (cathode).
Experiments have shown that after few
months, the corrosion current drops to
virtually zero.
• Thanks the few components the
system, driving both uncomplicated
and reliable.

Deep earthing system
Benefits
Elpress systems for deep earthing have
many advantages:
• The ground line has joints risk
of contact failure. For every 0.g. lead
sheathed cable located the soil few
metres from the earth connection, the
corrosion current from the lead anode to
the Fe+Cu earth connection 40% less
than the value earth connection
without rods. The amount the reduction
depends the properties the soil. soft hard copper, galvanized or
stainless steel.

Service life
Elpress deep-earthing system consists
of steel rods and copper line.
• The system has low overall weight
compared other systems.
Driving takes place with the aid a
power hammer with adapted driving
sleeve sledge hammer and impact
sleeve FS62C. The explanation that a
special layer the polarization layer is
formed next the electrode.
A hardened steel tip paves the way for
the ground line that inserted into the
steel tip and clamped the leading
rod.
