AN Wallis and Co Ltd
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.

Compression Terminals
Wallis cable terminals are manufactured from high-conductivity seamless copper tube and feature bell mouth entry for cables up to 500mm² and chamfered entry for cables 500mm² to 1000mm². All terminals are annealed, to avoid cracking and splitting when crimped, and electro-tin plated to combine maximum electrical conductivity with mechanical strength. An inspection hole is provided to check cable location prior to crimping.Request a Quote Supplied by AN Wallis and Co Ltd -

Copperbond Earth Rods
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 strength than cut-threads. The standard copper thickness is 0.25mm. Greater copper thicknesses are also available.Request a Quote Supplied by AN Wallis and Co Ltd -
