Lightning Arrestor
We offer lightning arrestor, e.s.e. lightning arrestor and ss lightning arrestor to protect buildings and tall structures from damage caused by thunder and lightning. Leveraging on our wide experience in manufacturing & marketing Lightning Arrestors, we offer superior devices that intercepts the flashes of lightning and transmits the current to the ground. These are metallic rod like devices placed at the apex of buildings and are connected to the ground by low-resistance cables.

E.S.E. Lightning Arrestor
We offer E.S.E. lightening arrestor, which protects structures such as high rise buildings from damage by intercepting flashes of lightning and transmitting their current to the ground. These arrestors are offer value to client owing to their good performance in toughest conditions. The E.S.E. lightening arrestors are made from best quality material such as SS that assure not only safety and improved performance. We offer lightening arrestors at industry leading prices and within very less lead time. Some highlighting features of ESE Lightening Arrestors offered are as follows:

Working Principle

When the downward leader gets close to the ground (about 100 meters above the point), it generates an electric field above it which increases until 100 kilovolts per meter. 

This is when the corona discharge effect takes place, changing suddenly from a position at the tip to an upward leader. (Refer to Video :How Lightning Terminal Works) These positive upward leaders suddenly move in the direction of the downward leader. One of the leaders, the closest or the one which has started earlier or the one which has travelled faster, enters into contact with the downward leader. Then, the ionized air channel is in connection with both the ground and the cloud, and the return stroke can take place, engendering a high lightning current of many kA.

The air terminal is a device for lightning protection with a spherical metal part fixed to the top. This sphere is insulated from the rod by a ring made from a material with very high electrical insulation properties. When a storm comes, the external electrode (sphere) charges under the influence of the electric field until the potential reaches a critical value from which a spark appears between the exterior electrode and the tip of the central electrode. The tip enables plasma to be created close by the tip. The plasma, in association with the intense electric field created close by the tip, constitutes the first stage of development of an upward leader. The spark produced at the top of the air terminal will initiate the advance of the discharge, engendering an upward leader moving in the direction of the downward leader.
