The equipotential busbar conducts the lightning current
into the earthing system

2.1.1 Insulated, high-voltage-resistant air-termina-
tion systems
The OBO isFang modular air-termination rod system
can offer fast and freely terminable solution for insu-
lated air-termination rods high for the
largest possible protection angle. If
this not possible, the insulated, high-voltage-resist-
ant isCon®
conductor can used achieve isol-
ated air-termination system within non-isolated sys-
tem.7 Types air-termination systems
Air-termination systems can either isolated non-
isolated systems; the two types can used com-
bination. Non-isolated systems are fitted directly the
object that protected and the down-conduct-
ors are routed along the surface the installation.7.
Isolated systems prevent direct strikes into the ob-
ject/installation that protected
