Lightning Protection System
ABG Interlinks Ltd is one of the leading Lighting protection solution providers in Bangladesh. We are specialized in design, supply, installation and testing of lighting protection system.
Early Steamer Emission (ESE) air terminal is an ionizing lightning rod use for external lightning protection system with innovative technology. This ESE air terminal is also known as active lightning rod. This is most advanced type lightning protection solution which accuracy is very high compare to conventional lightning rod. Compiles with NFPA 780, BNBC 2006, IEC, NEC, IEEE, LPI .
Conventional Type
In the conventional system lighting rod is engineered to protect the structure in event of a lightning strike. The lighting will strike the rod and the conductor cables will carry the lightning current from the rod to the ground through wires instead of passing through the structure.
We are one of the leading Conventional Lightning Protection System (LPS) provider in Bangladesh. We specialize in design, supply, installation, testing of Lightning Protection Systems. Complies with NFPA 780, BNBC 2006, IEC, NEC, IEEE
Surge Protection Devices
Surge protector is an appliance or device intended to protect electrical devices from voltage spikes in alternating current circuits. It is characterized by its capacity to safely discharge current with 8/20 µs wave form. We provide best quality SPD which is suitable for commercial use as well as residential use .
Electrical Materials supply & Installation
We supply all type of electricals materials as per customer’s requirement within a very short delivery lead time. We have multiple years of experience in designing, supervising, commissioning of new electrical system. Our technical teams has several years of experience working with well reputed engineering consultation and construction companies .
Working Procedure
Lightning protection systems are the modern development of the innovation pioneered by Benjamin Franklin.Today, lightning protection systems are in use on thousands of buildings, homes, factories, towers, stadiums, public places and even the Space Shuttle’s launch pad.It is very much essential for electrical appliances & building safety and human safely as well to get rid of unwanted electrical hazards.We ABG is always ready to provide service when it comesto safety. Our years of experience in the design and installation of Earthing and lightning protection system allow us to deliver high quality goods with best customer service. For designing and installing the lightning Arrestors earthing system we follow the NF C 17-102, IEC 62 305-3,NFPA 780, BNBC 2006 and many more standards
Installation conditions
Lightning Protection System with an ESEAT is made of
- → an Early Streamer Emission Air Terminal and its extension mast
- → two down conductors, or in case of several ESEAT oneconductor per ESEAT
- → a connecting link or test joint for each down conductor to enabling the earth resistance to be verified
- → a protecting flat to protect the down conductor for the last two meters above ground level
- → an earth designed to dissipate the lightning currents at the bottom of each down conductor
- → an equipotential bonding between each earth and the general earthing circuit of the structure. this one must be disconnected
- → protection measures against injuries to leaving being due totouch and step voltages (e.g. warning notice).
Our ESE type protection system products
ESE Air Terminal
We are offering OPR 30, OPR 45 & OPR 60 from world renowned brand ABB.
These OPR are earned through maintaining consistently high manufacturing quality.
Lightning stroke counter
Lightning stroke counter and recorder is used to store date and time of the impact as well as lightning current values.
This type of protection is especially recommended for radio stations and antenna masts when the area requiring protection is relatively small. A single rod air terminal protection is made up of:
This principle consists of dividing up and more easily dissipating the lightning current by a network of conductors and earths.A meshed cage installation has multiple down conductors and consequently provides very effective protection for buildings that house equipment sensitive to electromagnetic disturbance.This is because the lightning current is divided among the down conductors and the low current circulating in the mesh creates very little disturbance by induction. A meshed cage installation is made up of:
