It varies, according to their height, and the landscape (i.e. the levels of the ground) between towers, as well as upon any restrictions on where towers may be built. The determining factor is to ensure that the ground clearance of the conductors remain above their regulation clearance.

What is the capacity of power transformer for 132kva substation?
A 132 kV substation is normally called a grid substation. It would normally use two or more 132/33 kV transformers rated at 90 MVA, or two or more 132/11 kV transformers rated at 30 MVA.
What are the standard voltages for transmission?
The standard voltage for transmission is about 115 to 1,200 kV (long-distance transmission). The extreme high voltages are measured more than 2,000 kV and it is exists between conductor and ground.Answer for UKThe standard transmission voltages in the UK are 400 kV and 275 kV. Primary distribution voltages are 132 kV and 33 kV, and secondary distribution voltages are 11 kV and 400 V. These are all line voltages -i.e. voltages measured between line conductors.
What is mean of EHV substation?
Extra High Voltage substation. It generally 132 kv or higher
What is the voltage of a pylon?
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.CommentPylons, 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.
Minimum ground clearance for 765 kv Transmission Line?
Ground clearance132 kv - 6100 mm220 kv - 7015mm400 kv - 8840mm765 kv - 15000mm
Safety distance from 132kv power line?
The safety distance from a 132 kv powerline is 1.4 metres
What is the maximum distance allowed between two joints in a high voltage cable of 132 KV?
2feet
What is the capacity of power transformer for 132kva substation?
A 132 kV substation is normally called a grid substation. It would normally use two or more 132/33 kV transformers rated at 90 MVA, or two or more 132/11 kV transformers rated at 30 MVA.
Why only 11kv is used in power systems transmission line?
It isn't. In the UK, transmission and distribution voltages are 400 kV, 275 kV, 132 kV, 66 kV, 33kV, and 11 kV.
What is the distance to be maintained between a tower with high tension wires and a house plot?
33 kV line, it should be 3.7 mtrs

Why do you represent the voltages ranges in terms of 11kilo Volt in power system?
It used to be a convention to add 10% to allow for transmission losses, so the voltages were always described as 11 kV, 33 kV, 66 kV and 132 kV. Later standards in the UK grid are 275 kV, which is a multiple of 11, and 400 kV which is not.
What is mean of EHV substation?
Extra High Voltage substation. It generally 132 kv or higher
What is a 132 kv substation?
132kV substation is part of transmission and distribution of power in which the transmission voltage is 132kV. The substation is for stepping down or stepping up of the voltages to the required voltage. the substation also serves as a place where the transmission lines can be isolated, controlled and monitored. The substation consists of different equipment that is used to regulate, monitor and distribute the required power.Another AnswerIn the UK, 132 kV voltages are considered to be the lowest transmission voltages. Other transmission voltages are 275 kV and 400 kV. A '132-kV substation' is normally one in which this voltage is stepped down to a primary distribution voltage, usually 33 kV but, sometimes, 66 kV. As the previous answer points out, substations contain transformers, switchgear, busbars, and protection equipment.
Why Indian power system in multiples of 11kv?
Multiples of 11 kV are used in many countries. The idea is to deliver a round number of volts so you add on 10% to allow for line losses. So 10 kV becomes 11 kV. In practice lines are operated without a 10% voltage drop now because it represents an unacceptable waste of energy, but we have stuck with 11 kV etc. Common supply voltages used for area distribution are 6.6 kV, 11 kV, 33 kV, 66 kV and 132 kV.
What is the maximum acceptable tan delta value of 132 KV SF6 circuit breaker?
Less than 65 ohms
How much electricity does a pylon Carrie?
In the UK a line of pylons carrying the supergrid at 400 kilovolts can carry up to about 2000 Megawatts. Pylons also carry circuits working at lower voltages, 275 and 132 kV, 66 kV in some places, and on small pylons 33 kV.
