What is the voltage of a pylon?

Answer 1

there are 3 main types of power pylons,400,000volts(400kv) usually there are 4 wires on each arm,275,000volts(275kv)usually 2wires,and 132,000volts(132kv)usually 1 wire.

Comment

Pylons, or to give them their correct name, 'towers', are used in electricity transmission systems and, to some extent, in distribution systems. Their operating voltages depend on the electricity standards in the country in which they are used. As pointed out in the original answer, in the UK, transmission voltages are 400 kV, 275 kV, and 132 kV; towers are also used, in some cases, to support distribution lines that operate at 66 kV and 33 kV (although these are more-commonly supported on poles).

In most cases, each tower supports two separate circuits -one on either side of the tower- with each circuit comprising three 'lines' (L1, L2, and L3)- often with one circuit having its line sequence reversed.

As the original answer indicates, at higher voltages, each 'line' consists of 'bundled' conductors (four per line at 400 kV, two per line at 275 kV). The purpose of bundling these conductors is to reduce the electric field stress that would otherwise exist at the surface of single conductors.

Answer 2

Electricity towers (the correct name for 'pylons') are used to support conductors which operate at very high voltages. The magnitude of the voltages are determined by the appropriate standards for the country in which they operate. For example, in the UK, they operate at 400 kV, 275 kV, 132 kV and, occasionally, at 66 kV or 33 kV -although 66 and 33 kV lines are normally supported on poles. These voltages are termed line voltages.

Towers normally support two separate three-phase circuits(one circuit on opposite sides of each tower) comprising three groups of line conductor bundles per circuit. 400-kV 'lines' are normally bundled in groups of four individual conductors at the same potential hanging off each insulator chain, 275-kV line conductors are normally bundled in pairs, and the others as single conductors.
