Non-isolated systems are fitted directly the object that protected and the down-conduct- ors are routed along the surface the installation. 2. Isolated systems prevent direct strikes into the ob- ject/installation that protected.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. This can be achieved with air-termination rods and masts, but also by fixing the components with insulating GRP (fibre- glass-reinforced plastic) holders the building/install- ation protected
