Positioning & Height
TerraSteamer
®
ESE Terminal
The TerraSteamer® ESE Terminal tip should be at least 2 meters higher than the
area that it protects, including antennae, cooling towers, roofs, tanks, etc.
If the external installation for a given structure comprises several ESE Terminals
these are to be interconnected by a suitable conductor, unless it has to be
routed over a structural obstacle (cornice, parapet wall) with a positive or
negative level difference in excess of 1.5m (see Fig. A).
When ESE Terminals protect open areas such as playing fields, golf courses,
swimming pools, camping sites, etc., they should be installed on specific
supports such as tower mast, lightning poles, pylons, or any other nearby
structures which enable the ESE Terminal to cover the area to be protected.
The ESE Terminal height may be increased by means of an elevation mast. If the
ESE Terminal is steadied by conductive guy lines, these should be connected
at the bottom attaching points to the down conductors by means of suitable
conductors.
Preferred Installation Points
The architectural features favorable to the ESE Terminal installation should be
taken into account during the lightning protection system design.
Usually, these features are high structural points, such as:
•
equipment rooms on flat roofs
• gables
• metal or masonry chimneys
