My god people have become paranoid, survailence military law enforcment????
its a pole location marker, so the utility co knows where the pole is on the grid.
Depending on where you live the utility company might have to be able to associate it with a different Coordinate Position System, ie the foreign
label.
If there is an breakage in the system they can track it to the nearest located pole, there by knowing exactly where to send a crew.
High voltage lines, in most developed countries, are what is called 3 phase power or 3P, there are three separate lines each carrying a voltage whose
wave forms are spaced 120 degrees apart.
Thats why the hot wires are in groups of three.
Example:
here in the states we have 600v 3P 440v 3P and 240/220V 3P
and 208v synthisized 3P.
In the case of 240 3P each of the 3 "legs" carries 120V, plus a ground.
For industrial users, lets say a motor, two of the legs combine to give 240V and the third determines the "direction" of rotation, or flow of
electricity.
In the case of a 3P ac motor, you can hook any leg to any terminal and the motor will run, if the direction of rotation is wrong then you flip any
two wires on their terminals and the direction of rotation or flow will be reversed.
And to achieve a household voltage of 120V 2 legs are used.
There are connection diagrams for hooking up differnet voltages to a transformer to get different ouptput voltages, but these diagrams are inside of
the terminal box and not on the pole.
its a location marker for sure
