Air-termination mast for protecting special facilities such as biogas plants and free field PV systems against direct lightning strikes.
The masts are erected in a screw foundation.
No digging or foundation work necessary.
The screw foundation is screwed into the natural ground and fixed in place by three earth rods Ø20 mm, length 1500 mm (Part No. 620 151). These must be ordered separately.

The air-termination masts are designed according to Eurocode 1 (DIN EN 1991-1-4 + DIN EN 1991-1-4/NA).
These calculations are based on a natural ground pressure of 0.02 kN/cm² (e.g. loamy, sandy, gravelly soil of medium density).

Components:
– Air-termination mast, St/tZn and Al, tapered Ø70 / 60 / 40 mm
– Air-termination rod Al Ø22/16/10 mm, length 2500 mm or StSt Ø10 mm, length 1000 mm
– Screw foundation St/tZn, length 800 mm with braces, length 530 mm and M10 locking screws with lock nut
– Earth connection lug with hole Ø11 mm

Advantages:
– Easy erection due to tapered design St/tZn and aluminium
– If necessary, the air-termination mast can be easily removed from the screw foundation and put down
