Tag:power=pole/Gallery

Generally the decision between a power=tower and a power=pole is based on the power line the tower carries ( power=line and power=minor_line, respectively), but sometimes these examples of the towers and poles might be of help.

Examples of power=tower:

• 
  A typical power tower of steel lattice.
• 
  A bit smaller power tower with wooden vertical parts. High voltage, as seen from the insulators.
• 
  Another, yet a bit different. High voltage, as seen from the insulators.
• 
  A typical steel lattice power tower carrying a dual-circuit 230 kV / 60 Hz power line.
• 
  Steel lattice power towers carrying single-circuit and dual-circuit 115 kV / 60 Hz power lines.
• 
  A high voltage line tower with a staple shape structure.
• 
  A narrower-than-usual tower carrying a 110 kV line - tower fits on a highway median.

Examples of power=pole:

• 
  Typical Finnish 20 kV line (topmost), a transformer and the resulting 400 V line.
• 
  A branching minor_line, same voltage in all directions?
• 
  A typical wooden pole in a curve, vertical pole with a diagonal support pole.
• 
  60 kV line using mostly wooden poles but also steel poles whenever there is a slight turn.
• 
  The most typical pole in rural areas.
• 
  Simple wooden poles carrying 60 kV and 12 kV 60 Hz circuits and two ground wires.
• 
  A guyed wooden pole rated at 115 kV / 60 Hz.

Examples of features where the classification might not be immediately obvious:

• 
  An untypical power=tower right next to a power plant. Not very high voltage, as seen from the insulators.
• 
  Roseville Electric dual-circuit 60 kV line crossing below other power lines on a low and wide two-legged steel tower.
• 
  A variety of power lines (230/115/60/12 kV).
• 
  A SMUD dual-circuit 230 kV line on tubular steel poles.
• 
  The base of a large tubular steel power pole for a 230 kV / 60 Hz power line under construction.
• 
  On older power lines with wooden towers, bends are often constructed this way, especially at high altitudes: each cable is carried on a separate guyed pole (in the background, a regular two-legged tower). Since the entire power line is mapped as a single way (with cables=3), I tagged the trio of poles as a single tower, not as three separate poles.
