Earth Blocks

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.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 driving head protects the internal thread and the top of the solid copper earth rod from damage.These driving spikes enable solid copper earth rods to be driven easily into the ground.The stainless steel coupling dowel is used for joining stainless steel earth rods together.These clamps are used for joining earth rods to different sizes of standed copper conductir. The clamps have a high resistance to corrosion and are mechanically strong to ensure a lasting connection.Solid copper plates provide a long lasting earthing solution in palces where driving earth rods might be impractical. They are often installed in conjunction with Low-Resistance Earthing Compound or Bentonite.They are often used for potential grading and are a preferred option on installations such as telecommunications towers, where touch and step potential could cause problems.It is a grey, fine granular material used in place of other concrete aggregates such as sand. When mixed with cement and water it forms a permanent, electrically conductive concrete. The conductive concrete is ideal for use in difficult ground conditions. It is a permanent, stable and maintenance free solution to obtaining a low resistivity earth.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.The housing can have an internal earth bar fitted diagonally across in slots provided in the base.Special earth bars manufactured to customer requirements are also available. Recommended fixing by countersunk wood screw 1?? x No. 12 and No. 12 wall plug.These Wallis insulators are supplied with or wothout studs and locking nuts.The seal is particularly useful where internal earths are required such as in a basement building. Both single and double flange seals can be adapted to suit our full range of earth rod diameters by use of special compression rings and sealsWhen cast into concrete they connect the re-bar to the earthing or lightning protection system.These Wallis earth blocks allow earth conductor termination, or live conductor termination within a suitable, fully insulated housing.
