What is the transmission tower?
The transmission tower is a structure that is usually built to support and transmit transmission pipes of electricity. The term may also apply to towers used in the transmission of electromagnetic signals for telecommunications, such as mobile phone towers, and those towers used for the transmission of television and radio signals. In some areas of the world, the towers used for electricity transmission can be called other names such as pylons and water towers.
Electric transmission tower can be found almost anywhere in the world. In most industrial countries, conventional monuments are common and can be very large. The most common design method for the transmission tower is now called the design of the grid, in which the tower consisting of angular struts and trusses, usually made of solid steel or steel pipes. However, some transmission towers can be constructed from very large hollow steel poles, wood or concrete. Most of these types of towers Jeself Support, but some patterns may be stabilizGuy wires.
In general, these large structures are used only for transporting only the largest electrical lines, most often those that carry over 100,000 volts. The design differs very much from place to place and the typical transmission tower can be supported as little as one or two high voltage lines or tens. While most are below 300 feet (100 meters), some very large examples can be much higher.
The term transmission tower may also apply to those towers built and used for telecommunications and broadcasting purposes. For example, mobile phone towers such as relay or mobile phone signals. These towers, like electric towers, can be a grid or a one -time construction. Mobile phone gear towers often have support wires.
Some extremely high transmission towers are used to transmit radio and television signal. These departures can be highover 0.6 miles (1 km). They are almost always built of metal trusses, assembled in large sections on the ground before final construction. The transmission tower of this type is always stabilized by several strong guy wires to avoid swaying in strong winds. Warning lights are installed to warn aircraft of its presence. Radar installations sometimes also use such towers.
In the UK and parts of Europe, the transmission tower is often called a pylon, a term that avoids in the United States because the term pylon has other meanings there. In Canada and Australia, such a structure can be called a water tower, indicating the water source of force it carries. The towers are sometimes sub-classified according to the method that the wires are supported. For example, the soaked towers are designed to reduce the bend in the power line and the angular towers are used when the electrical line changes the direction.
