What else can I help you with?
What are old powerlines along railrd tracks ,made of?
powerlines mounted on pylons, see Overhead power line. For lines carrying information, see Overhead cable. An overhead line or overhead wire is used to transmit electrical energy to trains, trolleybuses
How can move the train with one transmission line?
There are always two. Live in the overhead line and neutral/earth in the tracks in contact with the wheels.
Why we can't send current or voltage without transmission line?
Well, there is no way of doing it without an overhead or underground transmission line.
Why overhead lines are far cheaper than underground cables for long distances and less economical for short distances?
First of all, the overhead lines are cheaper because they are bare, while underground cables are armoured and insulated, hence explaining the higher price. Overhead cables come of course with accessories like poles and insulators (mostly porcelain). For shorter distance, underground cables are preferred as the cost of pole erection does not exist.It's also worth pointing out that the cost of excavating a trench is more expensive than erecting an overhead line, and this cost escalates dramatically with higher voltage systems. For example, a 132-kV double-circuit underground line is between 5 and 8 times the cost of an overhead tower line, whereas an 11-kV single-circuit underground line is up to twice the cost of a wooden-pole overhead line.
What has the author Guido Semenza written?
Guido Semenza has written: 'Graphical determination of sags and stresses for overhead line construction' -- subject(s): Overhead electric lines
What size engines were in the 1999 poiniac sunfire?
The GT model had a 2.4L in-line 4, dual overhead cam with 4 valves per cylinder. The SE model had a 2.2L in-line 4, overhead valve with 2 valves per cylinder.
Why are tropics of cancer and Capricorn important?
The Tropic of Cancer is a line of latitude (23.5 o N) where the Sun is directly overhead at the Summer Solstice. The Tropic of Capricorn is a line of latitude (23.5 o S) where the Sun is directly overhead at the Winter Solstice.

An imaginary line in the sky directly overhead extending from north to south?
prime meridian
What is the the opposite of cancer?
The Tropic of Cancer is an east-west line on the map representing the northernmost place where the sun is ever directly overhead. It is debatable whether there is any such thing as the "opposite" of a line. But you could say the counterpart of the Tropic of Cancer is the Tropic of Capricorn, which is the line that is the southernmost place where the sun is ever directly overhead.
