How many feet away from overhead power lines should mechanical equipment be?

This depends on voltage level, line configuration, line height, loading, sensitivity of equipment, and on and on.
The further away the better. Voltage can be induced on equipment near power lines, so I recommend grounding out your equipment as well as possible just in case.

Distancebetween overhead power lines and houses?
20 feet.
What is the purpose of ground wires in overhead transmission lines?
connection of the ground of all the transmission lines and used as a communication cable between protection devices
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.
Three electrical hazards that may be present at a construction site are?
This may come from wet conditions, overhead power lines, and overloaded circuits but there are three main types of electrical hazards: Shock, Arc Flash and Blast and most electrical accidents result from one of the following three factors: unsafe equipment or installation, unsafe environment, or unsafe work practices.
How far should a scissor-lift be kept from power lines?
As far as possible! Here are the OSHA requirements. If the voltage is unknown stay 18 feet away. 13,000 - 69,000 volts10 feet115,000 - 138,000 volts11 feet230,000 volts13 feet500,000 volts18 feet This is no joke, the current will arc to equipment too close to the lines, and may make it near impossible to rescue the equipment operator. It's like being struck by lightning.
What has the author Vladimir List written?
Vladimir List has written: 'Mechanical design of overhead transmission lines'
Where does electricity go after it goes to the wooden overhead lines?
Overhead distribution lines are made of aluminium not wood.
What should you lookout for when launching a sailboat with raised mast?
Overhead obstacles - such as power-lines or bridges.
What should you look out for when launching a sailboat wih a raised mast?
You should look for anything overhead- bridges or lines of any kind.
What are mechanical lines?
Mechanica lines
Distancebetween overhead power lines and houses?
20 feet.
What are the materials added in electrical overhead lines?
Overhead electrical lines are usually made of aluminum, and some have a steel strand added which is used to give the conductor more strength (not to carry current).
How does the electrical energy coming from the power plant reachest the customer?
The electrical energy generated at the generating station reaches the consumer through the transmission and distribution systems. The transmission system generally consists of overhead transmission lines, towers, safety equipment and transformers and is used to transmit the generated electricity to the load centres (i.e. places where electrical energy is consumed). This energy is then distributed to various consumers using the distribution system - which consists of underground cables, overhead lines, transformers, safety equipment etc etc...
Are overhead power lines insulated?
Overhead power lines are insulated from ground, typically using strings of glass or ceramic insulators. The wire itself is bare, though - it does not have insulation on it. There are many different types of overhead power line, but I'm not aware of any that actually have insulation.
What are contour lines used for?
Contour lines enable us to see changes in elevation using an overhead map
Why overhead transmission lines would be more economical than underground transmission lines in high voltage transmission?
Overhead wires do not require insulation, and it is easier to plant poles than dig miles of trenches.
The minimum distance between the declination station and such objects as power lines and electrical equipment is?
Power lines and electronic equipment: 150m
