Lightning Protection System
In this contemporary world, the high-rise structures like buildings, chimneys, hospitals, airports, hotels and towers etc., adding a new trend in the modern lifestyle. But these heights of structures are inviting the risk of lightning strikes. For the purpose of protection, lightning protection system is the only solution. For more than a decade, JMV is a name in the External and Internal Lightning Protection for high-rise modern infrastructure, technological advancement in electronic devices and electrical installations.
JMV is providing the complete lightning protection solution from designing till installation as per latest IS/IEC 62305 and NBC 2016. We are having the skilled designing and servicing team who is having the vast experience in completing different projects like for high rise hotels/hospitals, airports, tunnels, metro stations, commercial towers, refineries etc. Also, our service team is very well skilled in structural lightning protection system with the steel reinforcement design of the building to provide the more aesthetic and practical solution as per IS/IEC 62305 and NBC 2016.
Also, being a leading OEM, we are manufacturing all the components required for the installation as per IS/IEC 62305 and all are tested as per IEC 62561 series. Being an OEM, the customization is also very possible for us with any component as per the requirement.
Lightning Protection System Components
A lightning protection system includes the following five parts: air terminals (lightning rods), conductors, ground connections (electrodes), bonding, and lightning arrestors.
Air terminals: Air terminals are metal rods installed at every projecting high point of a building—such as the peak, a dormer, a flagpole, or a water tank—to intercept a lightning smack. The air termination rods are available in Copper, AL or GI. Solid copper rods should be a minimum of 20mm in diameter, and solid aluminum rods should be a minimum of 13mm in diameter. Strategic installation of rods on a structure ensures that thunderbolt will strike the rods rather than another part of the building.
Conductors: Conductors are made up of copper clad steel or aluminum to provide the connection between the air terminals and the earth to direct the lightning strike deep into the earth where it can safely disperse.
Ground connections: Earthing rods, provide contact with the earth to securely dissipate the lightning charge. A minimum of two ground associations should be used for; additional ones may be needed for larger structures. The type of ground connection may depend on the resistivity of the surrounding soil. Grounding rods should be 12mm in diameter, 3m long copper-clad steel or solid copper rods driven at least 2.5m into the ground.
Bonding: Bonding involves branch conductors that offers protection against side flashes by connecting metal objects with the grounding system. Grounding is achieved when all electrical systems, telecommunication systems, and underground metallic pipes are connected to the lightning protection system.
