Supports for power lines

110-330 kV transitional steel supports
Transitional supports are installed at the interface device anchoring sites overhead lines and aerial gunner and perceived stress, similar to the intermediate supports, but from two overhead lines. Transitional supports are also affected by efforts from changing the direction of the wires during retraction and anchoring them to the arrow on the curve.
more35-1150kV intermediate steel supports
Intermediate direct support are installed in straight lines. At intermediate supports with hanging insulators, there wires are fixed in the supporting garlands hanging vertically, on supports with pin insulators binding - wire with a wire stitch. In both cases, the intermediate supports carrying horizontal loads from the wind pressure on the wire and on the vertical support and - the weight of conductors, insulators and its own weight.

35-1150kV anchor-angular steel supports
Angular supports are set at angles of rotation of line with the suspension wires in supporting garlands. In addition to the loads acting on the intermediate direct support, intermediate and anchor-tension towers perceive as the stress of the transverse components of tension wires and cables. When the angles of rotation of line power are more than 20 ° of angular towers of intermediate weight increases significantly. At large angles of rotation anchor-tension towers are set.
