What is length of the towers that is used on transmission lines?
That is depends on the factor of sag and clearance required. And also on the level of voltage transmission used.
Why you go for multi-conductor system in power transmission?
All a.c. transmission systems are three-phase systems, which comprise three line conductors which are suspended from towers. Each 'line' is generally made up of a number of 'bundled' conductors -according to the transmission voltage- to reduce the electrical stress. Many transmission towers carry two separate three-phase circuits, one on each side of the tower.
What is high voltage engineering?
It is a speciality in electrical engineering dealing with higher voltage applications such as employed in electrical transmission, switch yards and any applications requiring extraordinary power requirements. It is involved with such things as wire insulation, special designs to avoid arcing, power line towers and so forth.
The span of transmission line between towers takes the form of?
a resistor
How to calculate the the number of insulators used in a transmission line?
The glass, 'dish', ('cap and pin') insulators used to support conductors from transmission towers are each rated to withstand a specific voltage. But this voltage depends upon the standards used by the electricity industry of the country in which you live but, typically, they are each designed for operating voltages within the range 10 - 12 kV. By dividing the effective line-to-earth value of the transmission voltage, by this value, you will be able to determine the the 'basic' number of dishes required. This figure, however, will only be a guide, as the voltage gradient across the string of insulators is not linear. Furthermore, additional dishes are sometimes required according to the environmental conditions affecting the transmission line. For example, if the line is near the coast, the dishes might be subject to salt deposits; if the transmission line is near industrial factories (e.g. steel works) then the line might be subject to deposits from airborne waste from those factories, etc. So, often, the number of dishes will be greater than that number required to provide the basic insulation level.

High voltage current is needed for transmission but is low voltage is more useful?
A: Power transmission is in the range of 500 kilo volts as someone can tell the hi towers are far above ground and each phase is separated by ceramic insulators. Low voltage is necessary to manage these power safely to homes and business. That is why transmission becomes distributions and finally local power to us.
What are electrical transmission towers for?
Electrical transmission towers are meant to hold the power lines and to carry electricity.

Why use transposition tower in long transmission tower?
Transmission towers are usually made of steel to help support over the head power lines. They are used in high voltage AC and DC systems and can come in different shapes and sizes.
How many transmission towers in the US?
500
How do high altitude transmission towers get their power?
In exactly the same way as any transmission towers -one end of the line is connected to the step-up transformers in the power station.
Dangers of living near electricity voltage transformers towers?
Living near electricity voltage transformers towers, increases your risk of cancer and other health problems. Numerous studies done worldwide confirm this fact.

Who replaces light bulbs on cell phone towers?
They are replaced by employees of the maintenance departments of the various corporate utility entities that are responsible for the functioning and upkeep of the towers.
The span of transmission line between towers takes the form of?
a resistor
How tall are electricity transmission towers?
It depends upon the voltage; the higher the voltage, the taller the tower and the wider the right-of-way. A tower carrying 500,000-volt lines could be around 150' tall but it also depends on the terrain. The conductors have to be a certain distance from the nearest object, so power lines running across flat, open terrain can be on towers that are shorter than those used for lines running through the mountains, for example.
