Why do power lines droop from pole to pole instead of being taut?

It is physically impossible to pull any suspended medium tightly enough to get it perfectly straight. The force needed to pull any given length of power line between two poles tight enough to leave no drop by far exceeded the amount of force needed to snap that line in two. The effect of gravity upon that line cannot be overcome.

∙ 12y agoActually there is a great deal of tension, caused by the weight of the conducting wires. To get them taught [no apparent sag] would require much more reinforcing of the utility poles and insulators. It's much better to just space them out so that when they swing, they will not touch each other or surrounding objects.

What happens to a power line when it's a hot day?
The cable expands, so the lines may be observed to droop on excessively hot days. Conversly, the line tension has to be designed so they don't get too taught on cold days
What power lines send electricity over a nationwide network?
Transmission lines
What holds up power lines?
Electrical transmission towers are what holds power lines up. These towers are made of steel and have an openwork lattice design.
Power lines may do this on a hot day?

Why droop ct used in generators?
Droop CT is used to control load sharing of the reactive power b/w paralleled generators.

What is an example of a step-up transformer?
Power stations use step-up transformers to transmit power at a high voltage instead of a high current. This reduces the power lost in the transmission lines.
What is droop setting?
Droop setting is a feature in control systems that allows multiple generators to operate in parallel while sharing a load proportionally. It adjusts the speed and power output of each generator to maintain stability and balance the load. Droop settings help prevent one generator from taking on too much load and ensure a more even distribution of power among multiple generators.

Can birds touch one another when there on power lines?

No
Why are power outages more common during thunderstorms?
because the lightning hits the the power lines and electricity runs through power lines
