2. High-mast lighting - Wikipedia

   en.wikipedia.org/wiki/High-mast_lighting

   The pole that the lighting is mounted on is generally at least 30 m (98 ft) tall (under this height it is referred to as conventional lighting system), [1] while the lighting consists of a luminaire ring surrounding the pole with one or several independent lighting fixtures mounted around it. Most units have four, six or eight lights in the ...

3. Distribution transformer - Wikipedia

   en.wikipedia.org/wiki/Distribution_transformer

   Pole-mounted transformers may have lugs allowing direct mounting to a pole or may be mounted on cross-arms bolted to the pole. Aerial transformers, larger than around 75 kVA, may be mounted on a platform supported by one or more poles. [13] A three-phase service may use three identical transformers, one per phase.

   The pole can fly a 220-pound flag for in light wind conditions and a heavier 350-pound flag in higher wind conditions. [12] References This page was last edited on ...

5. Aviation obstruction lighting - Wikipedia

   It was instead lit by skybeamers mounted on small masts near the tower. This method was chosen as the mast was a mast radiator insulated against ground and for feeding the lamps on the mast otherwise special devices like Austin transformers would be required. Stuttgart TV Tower carries a rotating light assembly mounted atop, like used on ...

6. Photovoltaic mounting system - Wikipedia

   en.wikipedia.org/wiki/Photovoltaic_mounting_system

   The PV array consist of solar modules held in place by racks or frames that are attached to ground-based mounting supports. [11] [12] In general, ground mounted PV systems can be at the optimal tilt angle and orientation (as compared to roof mounted systems that can be non-optimal particularly for retrofits). Ground-based mounting supports include:

7. Lightning rod - Wikipedia

   en.wikipedia.org/wiki/Lightning_rod

   In overhead electric transmission systems, one or two lighter ground wires may be mounted to the top of the pylons, poles, or towers not specifically used to send electricity through the grid. These conductors, often referred as to "static", "pilot" or "shield" wires are designed to be the point of lightning termination instead of the high ...
