Teleszkópos villámvédelmi felfogóoszlop csavaros alappal
Air-termination mast to protect special facilities such as biogas plants, free field PV systems against direct lightning strike.
The masts are erected on a screw foundation.
No digging or foundation work necessary.
The screw foundation is screwed into the natural ground and fixed additionally by three earth rods Ø20 mm, length 1500 mm (Part No. 620 151) each, which have to be ordered separately.
These calculations are based on a natural ground pressure of 0.02 kN/cm2 (e.g. loamy, sandy, gravel soil of medium density).
