Design & Drawing
Installation & Rectification
In a lightning protection system, a lightning rod is a single component of the system. The lightning rod requires a connection to earth to perform its protective function. Lightning rods come in many different forms, including hollow, solid, pointed, rounded, flat strips or even bristle brush-like. The main attribute common to all lightning rods is that they are all made of conductive materials, such as copper and aluminum. Copper and its alloys are the most common materials used in lightning protection. In conventional system multiple air terminals is a must, whereas in ESE and CVM system single air-terminal protects a significant area.
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. The Down Conductor must be installed straight and vertically in order to provide the shortest and most direct path to earth. In conventional lightning protection system for every 100 ft. perimeter 1 down-conductor is necessary (recommended by NFPA 780). Conductors and Down-conductors are divided into two types: for building over 75 ft. class II is applicable and of buildings having lower height than 75 ft. class I is appropriate.
In a lightning protection system, a earth rod is an unavoidable component of the system. The earth rod requires a connection to earth to perform its protective function. It completes the path for lightning to go into the earth. For each earthing system a test point is necessary so that earth resistance value can easily be measured for future reference. Though different standard has recommended earth resistance to be less than 10 – 50 ohms, but in most standards it is recommended that it should be less than 10- 20 ohms. Therefore, to ensure proper function of lightning protection system earth resistance value needs to be carefully checked by professional engineers or contractors.
Our Premium Quality Materials
Here are some frequently asked questions.
Lightning discharges contain awesome amounts of electrical energy. It has been measured from several thousand amps to over 200,000 amps – enough to light half a million 100 watt bulbs! Even though a lightning discharge is of a very short duration (typically 200 microseconds) it is a very real cause of damage and destruction. 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.
Which constructions require LPS?
Bangladesh National Building Code (BNBC) gives clear regulations for setting up “Lightning Arrestor” recommended for buildings over 22m high and mandatory for buildings more than 33m high. It is obligatory to take the NOC (No Objection Certificate) for all realtors which comply with BNBC code.
International organizations working in Bangladesh like Accord Bangladesh, Alliance, ILO, Nirapon etc. has made LPS mandatory for every industry to get enlisted with them.
Is the government taking any step?
Fire Service and Civil Defense department and, Public Works Dept. (PWD) of Bangladesh government are working relentlessly in lightning awareness and protection in common people.

How LPS Works?
Lightning discharges contain awesome amounts of electrical energy. It has been measured from several thousand amps to over 200,000 amps – enough to light half a million 100 watt bulbs! Even though a lightning discharge is of a very short duration (typically 200 microseconds) it is a very real cause of damage and destruction.
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.
Our several years of experience in the design and installing Lightning Protection and Grounding Systems allow us to deliver best quality installations with outstanding customer service at an optimal value.
Does LPS attract lightning?
Rods and protection systems don’t attract lightning, nor do they influence where lightning will strike. They also do not and cannot prevent lightning, nor can they ‘discharge’ thunderstorms.
Can anyone design LPS?
Lightning protection systems (including placement of rods, cables, and groundings) are custom-designed for individual structures and require complex engineering to function properly. They should only be installed by qualified contractors.
