How high are electric pylons?

Question

and far apart are they

Answer 1

It's a function of their load, the cable weight, the distance between pylons and the overall configuration of the land it goes over.  Up hill/downhill vs. flat makes a differece.

Answer 2

Electricity is transmitted in many voltages.  The height and spacing of the pylons are set to ensure that the cabling doesn't sag below a specific height (between pylons) in relation to the ground.

In my state (Queensland Australia) common voltages are 500 Kv 275 kv 110kv 11 kv and 415 v. (kv =1000 volts)

The high voltages are used to transmit power between major centres the pylon are very expensive to build and the route of the line usually takes advantage of topographical features. I.E. they try to place the towers on hills so they can get much larger distances between towers. There can be many kms between these towers.

On the other end of the scale the power that is supplied to each house is usually fee from poles that are spared apart so that a cable can be feed to each house. This is usually spaced about two houses apart. The height of these poles can very as they can carry cables of different voltages.

Shortest poles for distribution to houses are around six metres tall (20 feet). The high voltage transmission towers are usually around 30-45 metres tall  (100-150 feet). There are a few freakishly tall towers in the world, a few would go taller that 100 metres (330 feet).

Answer 4

I'd say roughly 100m apart and 20 metres high but i don't think there is a set distance. Ok them boffins beat me but how sad can you get looking it up not you them

Answer 5

For voltage around a few thousand but distance apart I am not sure. Wouldn't it vary from place to place. May mention it on here:
