The Number One Supplier For All Your Surge Protection, Earthing And Lightning Needs
TOTAL SYSTEM PROTECTION
Lightning Transient Overvoltage Protection for Mains Power
All mains power lines entering or leaving the building are prime routes for lightning and switching induced surges and overvoltages to enter the electrical and electronic systems. Due to the large cross sectional area of these cables high current and voltage surges can enter with minimal attenuation.
By fitting Wallis Surge Protection devices in parallel with the incoming mains, surges and overvoltages can be reduced to an acceptable level. Protection devices are available for single and three phase as well as three phase split busbar systems.

Bentonite
Bentonite is a moisture retaining clay used as an earth electrode back-fill to help lower soil resistivity. The clay is a sodium activated montmorillonite, which when mixed with water swells to many times its original volume. Bentonite can be supplied in granular or powder form. The granular form is easier to handle as the powder can cause dust in windy conditions. Granular is the preferred option for filling trenches as the substance can be mixed in the trench. Powder is the preferred option for pouring into bore holes to ensure the mixture is a thin enough consistency to reach the bottom of the hole.Request a Quote Supplied by AN Wallis and Co Ltd -
Solid Copper Earth Plates
Solid copper plates provide a long lasting earthing solution in places where driving earth rods might be impractical. They are often installed in conjunction with Low-Resistance Earthing Compound or Bentonite.Request a Quote Supplied by AN Wallis and Co Ltd -
Solid Copper Earth Rods
These earth rods are designed for use where extremely high corrosion resistance and exceptionally long life are required. Solid copper earth rods are produced from solid copper bar and are internally threaded for jointing. When deep driving a solid copper earth rod the usual practice is to insert the rod into a bore hole and backfill with either Low-Resistance Earthing Compound or Bentonite.Request a Quote Supplied by AN Wallis and Co Ltd
