What is Lightning?What is Lightning?
Lightning is an enormous electric spark between the clouds and earth, Its power is difficult to understand but a single lightning flash may be 30 thousand amperes that’s about 200 million volts, and will take place within less than a second.
Lightning strikes are commonly referred to as "hot" or "cold", The difference is in the amount of power dissipated and length of time it takes for this dissipation "Hot" bolts have a higher current and longer duration time easily igniting combustible materials, "Cold" bolts have low current values, high voltage and short duration times, thus producing the violent shattering effect.
Why install a Lightning Protection System?
A properly designed and installed Lightning Protection System will protect lives and buildings against a lightning strike, Such a system is designed to safely carry the lightning strike to ground without damage to people or the building.
Lightning Protection System
A typical system will consist of a roof network of tapes, down conductors and earth electrode locations these conductors are usually copper or aluminium as are other components of the system. These metals and their alloys are specified not only for their electrical conductivity, but also for their corrosion resistance qualities.
What is Earthing?
Earthing is a safe method of carrying a lightning strike down to earth to dissipate safety while protecting Life and property.
Copper Earth Mats or Marconite Concrete?
These methods can be used in order to achieve a good Earth depending on the soil resistivity which can involve several factors ie moisture content ground make up etc. Our consultants will be able to advise you on the best option.
