Lightning Protection System (LPS) in Bangladesh
Last updated:
Every year, Bangladesh suffers from severe thunderstorms that put industrial factories and workers at massive risk. Therefore, the best way to protect your valuable building is with a reliable lightning protection system.
What is a Lightning Protection System?
A lightning protection system is a special safety network to catch high-voltage electric strikes. As a result, it holds the violent flow of a storm safely and directs it to the earth. Without this protection, a direct hit can start huge fires and destroy expensive factory equipment. In other words, this engineering setup is a shield to save human lives and physical properties.
Parts of a Lightning Protection System
A lightning protection system has several robust components working seamlessly together. First, the air terminals intercept the strike at the top of the building's structure. Second, this massive electrical current is safely carried down the factory walls by thick metal conductors. Finally, the specialized grounding rods discharge the high voltage deep into the earth.
Lightning protection system design & installation in Bangladesh
Before installation, the design of an industrial system must be carefully planned according to the local weather and soil conditions. In particular, engineers have to consider the building height, design and the specific soil resistance where the building will be constructed.
Lightning Rods
To begin with, air terminals should be placed at the highest points of your industrial roof. As a result, these copper or aluminum lightning rods attract the atmospheric discharge before it reaches the building. In this way, the lightning protection system protects the building from atmospheric discharge. So, when done right by technicians, it keeps the whole roof area within the safe zone.
Down Conductor
Next, the down conductors are heavy-duty metal cables which connect the roof rods to the ground. They have to go straight down the building to avoid dangerous arcing of electricity. The engineers space the cables evenly to distribute the high-voltage current safely.
Earth Rods
To create a strong grounding system, technicians pound thick copper-bonded earth rods deep into the ground. They provide a low-resistance path to instantly discharge the huge electrical surge to the earth. Properly installed rods will prevent the voltage from traveling back up into your factory floor.
Protect the Electrical System
Just shielding the physical structure is not enough to protect your internal automated control panels. You need to install a dedicated surge protection unit inside your main electrical distribution boards. Such smart devices stop transient overvoltages from traveling over the utility wires and destroying machinery.
Overall Solution
A full protection design includes external structural shielding and internal electrical surge suppression. This overall approach meets industrial safety compliance regulations and safeguards your whole capital expenditure. This makes your business resilient to harsh weather during the heavy monsoon season.
How is LPS installation in Bangladesh carried out?
LPS installation in Bangladesh follows the approved design drawing. A typical installation runs in this order:
- Earth termination first. Earth electrodes or an earth ring are installed and each pit is tested before the rest of the system is connected.
- Down conductors. Conductors are fixed down the building on the routes shown in the design, with test joints at a convenient height so each down conductor can be checked later.
- Air termination. Air terminals and roof conductors are installed at the positions given by the protection design, and roof-mounted equipment such as solar panels is bonded or protected.
- Bonding. Metal pipes, structural steel and other services are bonded so that dangerous voltage differences cannot build up during a strike.
- Testing and handover. Continuity and earth resistance tests are recorded, and you receive as-built drawings and the test report.

Frequently Asked Questions (FAQs)
How much does a lightning arrester cost in Bangladesh?
The price of a lightning arrester in Bangladesh is thirty thousand to three lakh BDT. This entire budget depends heavily on the brand, material quality, and your building size. The advanced digital tracking models are generally more expensive than the traditional solid copper air terminals.
Is a lightning protection system required by BNBC?
Yes, the current BNBC code does call for lightning defense systems for high-occupancy structures. Regulatory authorities require industrial factories and multi-story commercial buildings to install these networks during mandatory inspections.
What is the difference between a normal copper rod and an ESE lightning arrester?
A normal copper rod just sits there waiting for a lightning strike to hit it directly. By comparison, an ESE lightning arrester sends out upward streamers to attract the strike early on. Therefore, one ESE device covers a much larger surface area than conventional rods.
How often should a factory test its industrial grounding network?
In industrial facilities, the inspectors must verify the grounding grid resistance parameters at least once a year. Regular electrical safety audit checks ensure that seasonal soil dryness has not reduced grounding efficiency.
Can a lightning strike harm a factory if it hits nearby ground?
Yes, a near miss can cause dangerous shifts in ground potential that travel through pipes. Fortunately, the proper earthing system stops these stray currents from getting into your electrical system.
What does LPS installation in Bangladesh involve?
LPS installation covers earth electrodes or an earth ring, down conductors with test joints, air terminals and roof conductors, and bonding of metal services. Each part is installed to the approved design and the finished system is tested for continuity and earth resistance before handover.
