GPLUS – Guardian Plus Air Terminal

Guardian Plus Air Terminal Range

The new Guardian Plus air terminal range has evolved from the original Guardian CAT design and has been developed after taking into account the latest international research. Key elements include the effect of space charge and air terminal geometry, characteristics of long sparks, lightning characteristics and statistics, and the lightning attachment process itself.
* The design of the Guardian Plus air terminals is based on detailed modelling and calculations which optimise corona performance in the quasi-static phase of a thunderstorm
* Three domes sizes to cater for all practical installation scenarios
* Tip radius of curvature and tip protrusion is optimised to minimise corona discharge
* Robust materials to achieve long service life
