The line is a transfer item to carry the power from one point to another point.To avoid black out of the power, lines are interconnected, it is a grid.
Transmission Line Design Download Center ElectricalThe basic grid is, one power plant, one TD line and then one consumer, the most sophisticated are the international grids with simultaneously loops, and tree configurations. The grid notion allow to understand a great part of the TD lines problem, locations, nominal power of the line, design, and construction and operating trends. Description of the equipment The structures, the pylons Structures for overhead lines take a variety of shapes depending on the type of line. Structures may be as simple as wood poles directly set in the earth, carrying one or more cross-arm beams to support conductors, or armless construction with conductors supported on insulators attached to he side of the pole. High-voltage lines are often carried on lattice-type steel towers or pylons. Left: Anchor pylons or strainer pylons are employed at branch points as branch pylons and must occur at a maximum interval of 5 km, due to technical limitations on conductor length.; Middle: Branch pylon is a pylon that is used to start a line branch. The branch pylon is responsible for holding up both the main-line and the start of the branch line, and must be structured so as to resist forces from both lines.; Right: A tension tower with phase transposition of a traction current line for single phase AC 110 kV, 16.67 Hz. For remote areas, aluminium towers may be placed by helicopters. Poles made of reinforced plastics are also available, but their high cost restricts application. ![]() A large transmission line project may have several types of towers, with tangent (suspension or line towers, UK) towers intended for most positions and more heavily constructed towers used for turning the line through an angle, dead-ending (terminating) a line, or for important river or road crossings. Depending on the design criteria for a particular line, semi-flexible type structures may rely on the weight of the conductors to be balanced on both sides of each tower. More rigid structures may be intended to remain standing even if one or more conductors is broken. Such structures may be installed at intervals in power lines to limit the scale of cascading tower failures.
