Mast holder, heavy version

For erecting air-termination systems on installations, such as biogas plants

The heavy version of the mast holder enables the mounting of air-termination masts with a diameter of Ø55–100 mm

Telescopic Lightning Protection Mast with Screw Foundation

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.
These calculations are based on a natural ground pressure of 0.02 kN/cm2 (e.g. loamy, sandy, gravelly soil of medium density).

Telescopic Lightning Protection Mast for Bucket or Concrete Foundations

Air-termination mast for protecting facilities – such as biogas plants and free field PV systems, systems located in a hazardous area and ammunition depots – 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 information on the plug-in system, foundation and erection, please see the installation instructions.Advantages of the air-termination mast system:

Air-Termination Rods for Metal Roofs

For protecting roof-mounted structures, domelights, etc.
It is fixed at the end of the braces (Ø11-mm holes) by four holders for metal roofs.
The holders must be selected according to the roof profile (round standing seam part no. 123 040, clamping seam part no. 123 041, standing seam 123 042, without seam for riveting or screwing 123 043).

Air-Termination Rod for Trapezoidal Roofs

For protecting roof-mounted structures, domelights etc.
The air-termination rod is placed in the gap between the trapezoidal seams profile. The variable base frame can be adjusted to all trapeziodal profiles. The special holder for the air-termination rod can compensate roof inclinations up to 10°.

Air-Termination Rod for Ridge and Hip Tiles

For protecting solar thermal modules, photovoltaic generators or other roof-mounted structures on steep roofs.
The clamping bracket must be adjusted to the diameter of the ridge tiles before it is used to secure the air-termination rod.

Holders for Air-Termination Systems on Ridge and Hip Tiles

For air-termination rods or spacer bars with conductor holder, for protecting solar thermal modules, photovoltaic generators or other roof-mounted structures on steep roofs.
The holder is mounted using a tensioning strap. One clip is permanently fixed to one end of the tensioning strap. The holder can be adjusted to various types of ridge tiles using the adjustable clip at the other end.

Air-termination tips / rods or spacer bars have to be ordered separately.

Rod Holder for Gable Roofs

Base for fixing air-termination rods on steep roofs, with anti-rotation protection (toothed lock washer) and lock nut as well as boreholes for screwing the brace onto the roof battens.
At the chimney, the air-termination rod requires additional fixing e.g. by means of DEHNiso spacer.

Pipe Clamp for Air-Termination Rods

For fixing as well as lightning current carrying contact of the air-termination rod, e.g. on metal substructures of photovoltaic (PV) installations (square hollow profile); typically installed on steel frame or reinforced concrete structures. When mounted on pipes, the pressure plate (flat plate 2x angled) has to be removed. Two pipe clamps have to be installed on each air-termination rod.
The maximum free length of the respective air-termination rod according to the wind load must be considered for installation.

Angled Air-Termination Tips

For protecting, e.g. free field photovoltaic systems or carports with a PV system against direct lightning strikes.
A distance of 15-20 cm between the seam clamps and the free length of 80-85 cm should be ensured.
The air-termination tip is adjustable to the inclination angle of the PV system. The standard type is 55° angled which corresponds to a PV system inclination of 35°.

Air-Termination Rod Adapter

For vertical positioning of air-termination rods in case of roof inclinations up to 10°.
For concrete bases with fixing wedge (Part No. 102 010 or 102 340).

Air-Termination Tips

End cap for air-termination conductors.

Air-Termination Stud
