What does it mean to show how electricity power travel?

A power plant can supply a factory along cables or overhead lines. In that case the electric power produced from a primary fuel in the power plant has to travel along the cables to the factory. That is how electric power travels. A piece of theory by J.H.Poynting published in the 1890s showed that the power travels in the electric and magnetic fields surrounding the wires according to electromagnetic theory. This has never been demonstrated by experiment but it is entirely consistent with the laws of nature as expressed by J.C.Maxwell in his 'Treatise on Electricity and Magnetism' on which electrical theory and engineering is based.

Why why the electric lines are never have tightly between the poles?

During warm weather the cable will expand and sag slightly. If the cable had then been put up too tightly, when the cold weather arrived, the cable would contract and could snap or damage the fastening that clip the cable to the poles.In other words, the sag is to allow for expansion and contraction of the cables.
