Why 22kv 11kv 33kv 132kv 220 kv are standard transmission voltages in transmission lines why not 20kv 10kv etc?

Its just a matter of standard. In my area, for instance, we use 13.2 KV for distribution lines, and 69 KV / 138 KV for transmission lines.

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 are power lines run at high voltages?
Power lines run at high voltages to overcome line loss.
What is low tension lines?
Having a low voltage, or designed to work at low voltages.
What is the basic parameters of transmission lines?
the basic parameters of transmission lines are R,L,C and G...........
Why do power transmission lines not have neutral conductor?
No neutral is necessary, because the transmission line's line currents are roughly balanced and, so, the phasor sum of those currents will be relatively insignificant, rendering the need for a neutral conductor to be an unnecessary expense. In practise, for most transmission towers, each of the three 'lines' comprises not just a single conductor but, rather, a number of conductors which are bundled together in order to reduce electric stress surrounding the line. The number of conductors per bundle increases with transmission voltages. In the UK, for example, 400-kV transmission lines normally comprise bundles of four conductors, whereas 275-kV transmission lines normally comprise bundles of two, and 132-kV lines just one. Running along the top of transmission towers is an earthed conductor, called a 'guard conductor', whose function is to protect the lines from lightning strikes during electrical storms. Many transmission towers also have two, separate, three-phase circuits -one circuit on each side of the tower. But, definitely, no neutral!
What is a 380 132 substations?
it means..it is stepping up the power of 132KV to 380KV on the transmission lines.

What are the voltages in secondary transmission electric lines?
A: Those voltages are called distribution voltages to differentiate from transmission voltages. And that varies from state to state and locals . Usually around 10kv to 20 kv
What is a set of standards for digital transmission of data over standard copper telephone lines?
The set of standards for digital transmission of data over standard copper telephone lines is ISDN
What is transmission line amps rating?
High power transmission lines carry several hundred amperes up to 2000 amps at voltages up to 500 kV or higher
Do you transmit electric power via transmission lines at 50Hz or at some higher KHz?
Transmission lines also use 50 Hz. Transforming to lower voltages would become very complicated when also the frequency would have to be changed.
Why are power lines run at high voltages?
Power lines run at high voltages to overcome line loss.
Why does corona effect is more in village than in city under transmission lines?
for sake of safety and protection the high voltage transmission lines are erected in less populated areas ie. villages , these lines have operating voltages about 220kv , 440kv , 132 kv( high tension lines) . while in cities the voltage is distributed at low voltages ( about 11kv(industry) , 440v residential ) because of safety issue . since corona loss highly depends on the operating voltage of lines thats why it is mostly seen in villages.
Why transmission line voltage is like 6.6kv 11kv22kv 33kv etc?
Usage of such high voltages will increase the efficiency of the transmission lines and decreases the losses in the line. It also reduces the requirement of conductor size.
Where are the transmission cooler lines located on a 2003 Acura TL?
The 1999 - 2006 acura tl's don't have a transmission oil cooler. no cooler lines to the standard radiator either. Phil
Why is ac electricity transformed?
'Transform' means to increase or to decrease an a.c. voltage. Transformers are used to step up lower voltages to higher voltages, or vice-versa. Transformers are an essential component of electricity transmission and distribution systems, as they allow voltage levels to be changed very efficiently. For a given load, the higher the supply voltage, the lower the resulting load current. So very high voltages are necessary in transmission systems in order to transfer energy with relatively-low values of current -this leads to less voltage drops along the line, less energy losses, etc. Transformers are required to increase voltages for transmission at generating stations, and to reduce voltages for the users at the far end of the transmission/distribution lines. A.C. is actually less-efficient than d.c. for long transmission lines, but is more widely used because it is very complicated to transform d.c. voltage levels, because transformers do not work with d.c.
Why are transformers used for transmission of electricity into your home?
The voltage provided by power company are higher what your home uses so transformers step down the voltage for your house. Higher voltages in your home would cause a potential safety hazard. The higher voltages on transmission lines are used to cope with voltage drops over long distances.
