ISO Certification


Tokai Bipolar Air Terminal

Fully type tested, approved and in compliance to International Standards in Lightning Protection IEC 62305, IEC 62561, IEC 61643-11 and UL Certified.

Product Concept: How it works

When a thunderstorm approaches, Tokai Bipolar Air Teminal TKA 300 causes the advance discharge (corona) to neutralise the electric charge in the atmosphere, thus reducing the thunderstorm’s electric field and preventing the protected asset from being struck by lightning.
