Lightning Protection Systems

 

 

 

Lightning is a fast and instantaneous exchange of electric charges between Earth and cloud. The negative clouds are mainly stormy and are the base of lightning strikes. The lower part of the storm cloud is negatively charged when the cloud moves; it generates on the Earth a charge of equal value and opposite sign.  When the accumulation of charge exceeds a critical potential (when the voltage gradient reaches a value of about 10 KV/cm) a channel of electrodes leaves the base of the cloud in the form of a faintly luminescent reject and progresses rapidly toward the earth.

 

 

Material Specification


All Products in lightning protection are produced in accordance with BS 6651 standard that ensures a satisfactory life span of at least 30 years to ensure an effective system and a satisfactory long term performance. All fittings need to be mechanically robust and provide good corrosion resistance qualities in widely differing environments aluminum and copper the two metals most commonly used in lightning protection system particularly where they come into contact with each termination networks and down conductors, it has to be conducted to copper at or around the test clamp.

This connection should be positioned at the beginning of the earth termination network. 

 

 

 

Copper Bonded Earth Rods

 

Copper Bonded Earth Rods or ground rods are the ideal driven earth electrodes; they offer the installer an economical and efficient earth rod grounding system.

Electrolytic copper is uniformly molecularly bonded onto a high tensile steel core to a pure thickness from 25-250 micron, thus ensuring excellent corrosion resistance and eliminating electrolytic action.

The high tensile steel core ensures strength and hardness allowing the use of power hammers for deep driven systems.

Coupling threads are formed by a rolling process to ensure thread strength and to maintain the integrity of the molecularly bonded copper. The universally used thread rolling technique raises the surface of the rod.

Standard: BS 6651 / UL 467.
