Introduction
The arrester system in Bangladesh is essential for protecting buildings, electrical infrastructure, and sensitive equipment from lightning strikes and voltage surges. Himaloy Engineering provides professional solutions that meet the National Electrical Code (BNBC) standards, ensuring safety, reliability, and compliance for residential, commercial, and industrial structures.
Understanding the BNBC and Its Role
The Bangladesh National Building Code (BNBC) provides guidelines for building safety, including electrical systems and lightning protection. It establishes standards for installing arrester systems in Bangladesh, ensuring that electrical installations are safe and capable of withstanding surges and lightning strikes.
Himaloy Engineering follows these codes strictly to provide systems that not only protect property but also comply with regulatory requirements.
Importance of Arrester Systems in Compliance with BNBC
Protecting Life and Property
The primary goal of BNBC standards is to ensure human safety and protect structures from fire and electrical hazards caused by lightning. A compliant arrester system in Bangladesh helps prevent injuries and loss of property.
Safeguarding Electrical Infrastructure
Buildings equipped with BNBC-approved arrester systems maintain reliable electrical operations. High-voltage surges can destroy equipment, disrupt operations, and incur financial losses. Properly installed arrester systems mitigate these risks.
Enhancing Operational Continuity
For industrial and commercial facilities, downtime due to lightning-related damage can be costly. BNBC-compliant arrester systems ensure uninterrupted operations by protecting electrical and electronic systems from surges.
Key BNBC Requirements for Arrester Systems
Placement of Lightning Arresters
BNBC mandates that air terminals (lightning rods) should be installed at the highest points of a building, including rooftops, towers, and chimneys, to intercept lightning effectively.
Proper Grounding
A critical BNBC requirement is the installation of a grounding system with low resistance. Grounding safely dissipates lightning energy into the earth, preventing fire, structural damage, and electrical hazards.
Down Conductor Specifications
BNBC specifies adequate down conductor sizing and routing to minimize resistance and potential side-flashes. Conductors must be securely fastened to prevent mechanical stress and ensure efficient energy flow to the ground.
Surge Protection Devices
BNBC encourages the integration of Surge Protection Devices (SPDs) in electrical systems to safeguard sensitive equipment. These devices prevent damage from transient overvoltages and ensure compliance with safety standards.
Inspection and Maintenance
Regular inspection and maintenance are essential under BNBC guidelines. Buildings must undergo periodic checks to ensure that arrester systems are functional, properly grounded, and capable of handling lightning strikes.
Types of Arrester Systems Compliant with BNBC
Conventional Lightning Arresters
These systems use air terminals, down conductors, and grounding electrodes. They are widely adopted in residential and commercial buildings in Bangladesh.
Early Streamer Emission (ESE) Systems
ESE systems offer advanced lightning protection by attracting strikes earlier, providing enhanced coverage for high-rise and industrial structures.
Surge Arresters
Designed for electrical and electronic equipment, surge arresters protect sensitive devices from voltage spikes, ensuring operational continuity in compliance with BNBC standards.
