This unit provides the design engineer with an air termination relatively free of space charges, which is capable of creating ionization and which concentrate electric field to release free electron on the approach of a lightning leader. As a result, mostly only one lightning conductor is required against a large number of Conventional Lightning conductors This Advanced Lightning conductor is a dynamic device which has a very strong central ion generating system that is able to generate ions and requires no external source of power supply.
A Spike Lightning Protection Rod is a single componet in spike lightning protection system. To Protect home or building in the event of lightning. a metal conductor is mounted on the top of the building and electrically connected to earth through a wire which is known as conventional lightning rod or spike arrester.
