Lema Trading Ltd. completed a Lightning Protection at the office building of the CNSys Company on 44-46 “Lerin” Str. The Lema Trading’s experts had used products of the Greek company ELEMKO S.A. The air Termination Rod which was used for the Lightning Protection was CIRRUS II with triggered time of 45 µs. The mast of the air Termination Rod is made of a hardened steel which provides a longer life in the corrosive atmosphere. Due to the specificity of the site, a special LCCC cable (Lightning Current Control Cable) 50mm² was used, designed for implementation of signal-trigger systems.
