Introduction :
Choosing the right Lightning Arrester system in Bangladesh is essential for protecting buildings and electrical equipment from lightning strikes. Power Ark Engineering provides expert solutions tailored to various structures, ensuring effective protection and compliance with safety standards across residential, commercial, and industrial setups.

Understanding Lightning Arrester Systems

A Lightning Arrester system in Bangladesh is a crucial safety component that prevents electrical damage caused by lightning strikes. By safely diverting high-voltage surges to the ground, these systems protect lives, equipment, and property. Understanding the types and their applications is essential for optimal protection.

Why Lightning Arrester Systems Are Important

  • Equipment Protection: Safeguards sensitive electrical devices from voltage spikes.

  • Fire Prevention: Reduces the risk of fires caused by lightning-induced surges.

  • Operational Continuity: Ensures uninterrupted operation of industrial and commercial facilities.

  • Compliance: Meets national and international safety standards.

Power Ark Engineering ensures each system installation is tailored to meet these safety objectives.

Main Types of Lightning Arrester Systems in Bangladesh

There are several types of lightning arrester systems, each designed for specific applications and building types. Selecting the right type depends on the structure’s design, height, and electrical setup.

1. Rod-Type Lightning Arrester

Rod-type arrester systems are the most common:

  • Air Terminals: Installed at the highest points of a structure to intercept lightning.

  • Down Conductors: Safely channel the lightning energy to the ground.

  • Uses: Ideal for residential buildings, small commercial structures, and educational institutions.

Power Ark Engineering ensures proper placement and secure installation for maximum efficiency.

2. Sphere-Type Lightning Arrester

Sphere-type systems use metallic spheres to protect structures:

  • Mechanism: Spheres create an electrostatic zone that attracts lightning.

  • Applications: Suitable for industrial plants and large-scale commercial buildings.

  • Advantages: Provides extended coverage area and higher safety margins.

3. Mesh or Cage-Type Lightning Arrester

Mesh or cage-type systems cover large rooftops with interconnected conductors:

  • Design: A network of copper or aluminum conductors forms a protective cage.

  • Uses: Effective for warehouses, factories, and stadiums.

  • Benefits: Offers extensive surface protection and reduces strike risk for expansive areas.

4. Early Streamer Emission (ESE) Lightning Arrester

ESE systems actively emit upward streamers to intercept lightning:

  • Technology: Accelerates ionization to attract lightning before it hits the structure.

  • Applications: High-rise buildings, tall industrial towers, and critical infrastructure.

  • Advantages: Reduces the probability of lightning striking unprotected points.

Power Ark Engineering specializes in designing and installing ESE systems with precise calculations for maximum safety.

5. Surge Protection Devices (SPDs) as Arrester Systems

SPDs complement traditional arrester systems by protecting internal electrical circuits:

  • Function: Absorb and divert transient overvoltages.

  • Applications: Essential for offices, hospitals, and industrial equipment rooms.

  • Benefits: Prevents damage to computers, servers, and sensitive machinery.

Factors to Consider When Choosing an Arrester System

Selecting the appropriate Lightning Arrester system in Bangladesh involves evaluating multiple factors:

Building Height and Structure

  • Tall buildings may require rod-type or ESE systems.

  • Flat, expansive structures benefit from mesh or cage-type systems.

Environmental Conditions

  • Consider storm frequency, local lightning activity, and surrounding landscape.

  • Coastal areas may require corrosion-resistant materials for long-term durability.

Electrical System Complexity

  • Evaluate internal electrical loads and sensitive equipment.

  • Integrate SPDs to provide comprehensive surge protection.

Supplier Expertise

  • Choose a reliable supplier with certified products and professional installation services.

  • Power Ark Engineering provides expert guidance and tailored solutions for all building types.
