COMPREHENSIVE LIGHTNING PROTECTION PRODUCTS
A lightning protection system
safeguards structures from the destructive effects of lightning by safely directing
high-voltage currents into the ground. Because lightning strikes are unpredictable,
proactive protection is essential.
Modern electronics—such as computers, networks, CCTV, sensors, PLCs, and UPS systems—are
especially vulnerable to lightning and power surges. Surge protection is vital to shield
internal systems from electrical transients.
An effective system typically includes conductors, strike rods, ground terminals, and
bonding to reduce side-flashing. Surge protection devices are also integrated to prevent
damage to power, data, and communication lines.
Regular maintenance and safety inspections are crucial to ensure the system remains
fully functional over time.
Air terminations are components specifically designed to intercept lightning strikes. These include vertical rods, mesh conductors, catenary wires, and natural structural elements. Their placement follows the chosen protection design and ensures full coverage. All air terminations must be interconnected and linked to down-conductors, with expansion joints included where necessary for mesh and interconnections.
Down-conductors are used to provide the interconnection between the air terminations and the earthing termination to carry the lightning current.
An effective earthing system is crucial for safely dissipating lightning energy. It should offer a low-impedance path, reduce touch and step potential risks, and ensure long-term reliability, especially in hard-to-reach areas. According to IS/IEC 62305, the lightning protection earthing must be interconnected with other earthing systems—separation from power, telecom, and other systems is not advised.
Equipotential bonding prevents hazardous sparking between lightning protection components and the structure when proper separation distances can't be maintained. Key areas to bond include incoming external services (e.g., power, gas, telecom), metallic elements entering the building, internal structural metals (like handrails or ducts), and internal electrical or electronic systems.
