electric-power transmission lines carry power from generating plants (see electric-power generation) to the distribution systems that feed electricity to domestic, commercial and industrial users. Transmission lines vary from a few kilometres long in an urban environment to over 1000 km for lines carrying power from remote hydroelectric plants. They may differ greatly in the amount of power carried. Because requirements vary, many technical, economic and environmental factors must be considered when new lines are planned.Electrical power line routes are designed based on geography and the available paths according to easements, placement abilities and the ultimate destination. Surveyors work to maintain straight lines along the route as much as possible, but angle towers are needed each time the line takes a directional change. The angle means the tower must support the directional change. Anchors are added to the tower to counteract the pressure placed against the angle. The angle or tension-style tower is more heavy duty than a regular suspension tower because it must support a greater load.
