WALLIS

Wallis copperbond earth rods offer installers the most
economical method of achieving a low earth resistance.
Each rod has a high tensile strength, low carbon steel core.
99.95% pure copper is applied electrolytically and forms a
metallurgical bond between the steel core and the copper.
This combination makes the rod ideal for deep driving whilst
also provides lasting resistance to corrosion.
The threads are formed by a cold rolling process which
ensures strength and maintains the molecularly bonded
copper covering along the full length of the threads.
Cold-rolled threads are stronger than cut-threads.
The standard copper thickness is 0.25mm. Greater copper
thicknesses are also available. Please contact our sales office
for further information.

The disconnecting link provides a temporary break in the
earth connection to allow inspection and testing of the
earth electrode.

A. N. Wallis earth bars provide a convenient common
earthing point for electrical installations. Our standard
earth bars are manufactured from 50mm x 6mm hard
drawn copper bar and come complete with M10 fittings
and insulators. The PVC base makes our earth bars
lighter and easier to handle as well as being entirely
corrosion proof.
Special earth bars manufactured to customer
requirements are also available.
Recommended fixing by countersunk wood screw
1 ½” x No. 12 and No. 12 wall plug.

excess of 99.9%.
The A. N. Wallis double disconnecting link earth bars are
mainly used to offer a temporary break in the connection
to the earth, allowing the inspection and testing of multiple
earth rods / systems while disconnected from the lightning
and earth system.

This versatile range of Wallis ‘U’ bolt clamps can be used
to connect flat tapes and stranded cables to earth rods,
reinforcing bars (rebar), hand rails etc.

Used to connect flat tapes in a horizontal position on the rod.

These Wallis high-strength couplings are used for joining
copperbond threaded earth rods together. They facilitate deep
driving and ensure continual contact between the rods both
during and after installation.
The coupling also protects the earth rod threads during
installation with the threaded driving head. There is a lead-in
for ease of assembly and the hexagonal design allows for grip
and keeping the coupling tight when driving into the ground. All
Wallis couplings are manufactured from a high copper content
alloy ensuring excellent corrosion resistance.
