Air-termination mast for protecting special facilities such as biogas plants, free field PV systems, Ex systems and ammunition dumps against direct lightning strikes.The masts are erected in a bucket foundation (pre-fabricated) or an on-site concrete foundation with foundation basket (to be ordered separately).For detailed imformation on the plug-in system, foundation and installation, please see in installation instructions No. 1729.This air-termination mast system ensures that entire systems / areas are located in the protected volume (lightning protection zone 0_B) without installing horizontal air-termination systems (spanning cables).The separation distance s according to IEC/EN 62305-3 between the air-termination mast and the object to be protected must be observed. The air-termination masts are dimensioned according to Eurocode 1 (DIN EN 1991-1-4 + DIN EN 1991-1-4/NA).Advantages of the air-termination mast system:

• Excavation work can be completed in advance
• Erection in (prefabricated) bucket foundation on site with comparatively little effort, or
• Erection in on-site concrete foundations with foundation basket (concrete curing time to be observed for scheduling and erection)
• With flange plate for fast mounting
• Easily adjustable with M24 threaded bolts
• Detailed mounting instructions
• Verifiable statics (upon request)

Components:

• Air-termination rod, St/tZn, Ø42 / 25 / 15 mm, length 2400 or 5400 mm, with M20 thread and lock nut
• Conic mast segments
• Flange plate with connection lug for earth connection hole Ø12 mm (for round conductor Ø10 mm, e.g. with KS connector (Part No. 301 019))

Max. transport length 6 m.
