Conventional System Designed in accordance with NFPA780 and BNBC

  • Scientifically known as Franklin Rod & Meshed Conductor System
  • Need Multiple air terminals along the edge and through roof. Also, one down conductor for every 100 ft. of accumulated perimeter
  • Proven, most trusted and mostly used Lightning Protection System
  • Approved by NFPA, LPI, IEEE, IEC and many more
  • Custom Designed for individual building
  • Require complex engineering to function properly

Major Components LPS designed in accordance with NFPA780 and BNBC

Air Terminal: The air terminal requires a connection to earth to perform its protective function. Copper and its alloys are the most common materials used in lightning protection.

It has to be the highest point within its range

Down Conductor: The Down-Conductor is that part of the external Lightning Protection System (LPS) that conducts lightning current from the Air Terminal system to the Earth Termination system.

Down Conductor must be installed straight and vertically to provide the shortest to earth

Earthing System: The earth rod requires a connection to earth to perform its protective function. This protects structures from damage due to lightning strikes and dilapidates the lightning to the ground

It is recommended that earth resistance value should be near 10 Ω

What is Lightning Protection System?

Lightning is a gigantic electrical spark!

It has been measured Lightning discharges contain from several thousand amps to over 300,000 amps – enough to light half a million 100 watt bulbs!

The function of an external lightning protection system is to intercept, conduct and disperse a lightning strike safely to earth. Without such a system a building’s structure, electronic systems and the people working around or within it are all at risk.

Conventional (Franklin Rod Method) LPS

  • Custom Designed for individual building
  • Require complex engineering to function properly
  • Single air-terminal can cover up to 50 ft. radius
  • Two classes of conductors used: Class I and Class II
  • Depending on building perimeter, two or more grounding facility required
  • Highly recommended for industrial sheds and buildings
  • Traditional and proven technology
