Earth Rods And Earthing Clamps The Basics
An earthing system is only as good as its worst connection, and that is usually the clamp rather than the rod.
Where Earth Rods Are Used
Earth rods appear wherever a site needs a reliable connection to ground independent of the supply. The listed applications for this range are petrochemical plants, oil storage, power stations, transformer substations, telecommunication stations, airports and network stations. What those sites share is that a failed earth is discovered during a fault rather than during an inspection, which is why specification tends to be conservative.
The Clamp Is The Weak Point
Rods are simple and generally survive. Connections are not. A clamp that loosens as the ground moves, or corrodes where two dissimilar metals meet, raises resistance quietly and nobody notices until a test. Specifying the earthing clamp with the same care as the rod, and ordering them together so the pairing is known to fit, avoids the most common failure in an earthing installation.
Customisation Is Normal In This Category
Earth rods are listed here as customisable. Length, diameter and coating are specification decisions driven by soil conditions and local standards rather than by catalogue convenience, so a supplier who expects to make them to your figures is more useful than one offering a fixed range. Send the specification you work to rather than choosing from a list.
Order Earthing With The Rest Of The Protection Package
Earthing hardware is normally bought by the same people ordering cutout fuses, energy meters and change-over switches. Putting them on one order is what makes a modest quantity of clamps worth shipping, and it keeps the site supplied from a single delivery rather than three.

Power Distribution And Utilities
Utility and network buyers order protection and metering hardware in volume against a written specification. This range covers the low-voltage end of that list.
Specification And Selection Support
Half the questions we get before an order are not commercial, they are technical: which tape, which way count, which busbar pitch. Getting that right before the order is cheaper than getting it right after.
Questions On This Topic
Can earth rods be made to our specification?
Yes, the earth rod is listed as customisable. Send length, diameter and coating requirements.
Do you supply the clamps as well as the rods?
Yes. Earthing clamps are listed as accessories in the same category, and it is worth ordering them together so the pairing is known to fit.
What industries are these used in?
The listed applications are petrochemical, oil storage, power stations, transformer substations, telecommunication stations, airports and network stations.
