Why comprehensive lightning countermeasures are necessary As experts in comprehensive lightning countermeasures, we at Sankosha work to address our customers’ diverse needs. What is lightning? ◇ How lightning happens ◇ Increased lightning damage Lightning is a natural phenomenon, similar to static In the information society, communication equipment has become more compact because of the spread of digital communication electricity. equipment that uses many electronic parts and components, and it tends to be more vulnerable lightning than analogue equipment.

When cold air enters the upper atmosphere and Movement of energy means that there are many more entry routes for lightning, and a greater possibility of suffering lightning damage. there are updrafts caused by the earth’s surface being (lightning: cloud to cloud) Lightning surge entry routes can vary greatly depending on the conditions, and this is why it is important to cover every imaginable heated by the sun, then thunderclouds will be formed.
