III. Introduction of the lightning arrestor
Since collectors are mounted on roofs, they are vulnerable to lightning strikes. Therefore, they shall be mounted in
the area which is well protected against lightning. If there isn’t any lightning arrestor, to protect the plate collector,
a lightning rod or grounding line is required. The following is a simple drawing for mounting the lightning rod on
a flat or sloped roof:
●
The drawing for mounting the lightning rod on a flat roof:
The lightning rod can be welded onto a frame, or an independent lightning rod can be manufactured and it can be
fixed with a wire rope.
●
The drawing for mounting the lightning rod on sloped roof:
Making an independent lightning rod is recommended; it can be fixed with a wire rope and the equipotential
bonding shall be applied between it, the frame and the lightning belt.
