Lightning Arrester

Lightning is a naturally occurring electrostatic discharge during which two electrically charged regions in the atmosphere or ground temporarily equalize themselves causing an instantaneous release of energy.

Lightning has been recognized as one of the most powerful, spectacular and all‐pervasive atmospheric hazards that mankind has encountered throughout history

Lightning is often followed by thunder, an audible sound caused by the shock wave

One Lightning Strike is equivalent to; 2 million (V) or 2OO, OOO (A)

Lightning Hazards

On Living being:

  • Tingling Sensation230 V -1 mA
  • MAX Harmless Current5 mA
  • Can’t let go 10-20 mA
  • Fibrillation-Tissue damage100-300 mA
  • Heart arrest, Burns, Death10000 mA

Lightning strikes kill more people in India than any other extreme weather event but they go largely unnoticed. In 2018, over 3,000 people died due to lightning strikes in the country. Global estimates range from 6000 to 24000 fatalities per year.

As per Climate Resilient Observing Systems Promotion Council (CROPC) “The number of deaths resulting from lightning strikes has increased by 1000 over the past three years,”

Why Network Techlab?

We Believe – “When lightning roars, go indoors!

Why? Because House & Building are Lightning Proof

How? House & Building have a lightning protection system which makes them lightning proof.

We at Network Techlab believe in innovating and Engineering the best solutions and services to protect people and structures against lightning.

Our expertise includes:

State-of-the-art lightning solution, sophisticated lightning protection system design, tailored lightning risk assessments and many more

What is lightning protection system?

A lightning protection system is a passive means of preventing property damage from the effects of a lightning strike. It works by providing the electric charge produced by the clouds a path of least resistance to the ground.

There are 3 main components of a lightning arrester system

  1. Copper air terminals
  2. Copper cable / Strip
  3. Chemical earth pit

We have 3 variants Air Terminals:

  1. Lightning Rod
  2. Spike Lightning Terminal (Protection Radius up to 10m)
  3. ESE Lightning Arrester (Protection Radius up to 110m)

What is lightning protection system?

An earthing system or grounding system connects specific parts of that installation with the earth’s conductive surface and discharge the lightning strike safely into the ground. Traditional earthing System consisted of Plate Type and Pipe Type arrangements.

Traditional Earthing System

Disadvantages of Traditional Earthing System:

  • Frequent Maintenance
  • Short Life
  • Corrosive –Salt
  • Fluctuating Resistivity
  • Frequent Dead Rating
  • Difficult/ Time Consuming Installation
  • Larger Area Required
  • High Cost

How Chemical Earthing proved to be beneficial:

  • Maintenance Free
  • Larger Durability
  • Anti-Corrosive Compound
  • Stable Resistivity
  • Easy Installation
  • Space Saving
  • Cost-Effective
Chemical Earthing

“It’s better to be thousand times careful than once dead”!
