Operators of facilities with potentially explosive atmospheres are obliged to divide these plants/structures into the different explosion-hazardous areas. For these facilities lightning has to be considered as a potential source of ignition. National regulations on health and safety at work require documentation of the protection against explosion which specifies the different hazardous areas.

The HVI power Conductoris suitable for use in hazardous areas of Ex zone 1 (gases, vapours, mist) and Ex zone 21 (dust). The special installation conditions safely prevent electric sparks to neighbouring metal parts when lightning current flows through the HVI power Conductor.
