In addition the conductors, earth rods and

easy access earth electrodes and conductors
to facilitate this procedure. Earth inspection pits
Regular inspection and testing the earthing

4. Conductors
We offer three types conductor:
• Flat tape
• Solid circular
• Stranded cable
It important that earthing conductors should be
correctly sized for their application, they may
be required carry considerable current for
several seconds. Compression connectors
For applications where exothermic welding not
appropriate for creating permanent connections,
compression connectors may used.

An effective earthing system relies joints

conductivity with high mechanical strength.
3. Earth rods
Earth rods take advantage lower resistivity

will allow. Below ground, copper the
most common choice due its high resistance
to corrosion.
Earthing systems typically fall into (but are not
limited to) one the following categories:
• Power generation, transmission and distribution
• Lightning protection
• Control undesirable static electricity
• Telecommunications

2. Mechanical clamps
Where permanent connections are not

solution.
