A steel tower supporting high-tension wires is a critical component of electrical transmission infrastructure, designed to carry high-voltage power over long distances. These towers are engineered to withstand environmental stresses, such as wind and ice, while maintaining structural integrity. Typically constructed from galvanized steel for durability, they ensure the safe and efficient transfer of electricity from power plants to substations and ultimately to consumers. Their design also minimizes the risk of electrical hazards and ensures compliance with safety regulations.
33 kV line, it should be 3.7 mtrs
some items are : cutlery, pens, file cabinets etc... just think about everyday things :)
That depends on the load.
The various uses of carbon steel depend on the amount of carbon added to the alloy; for instance, carbon steel with the lowest amount of carbon is called wrought iron and is used for things like fencing. Medium-carbon steel, also called mild steel, is the type of steel that is used for structural purposes in buildings and bridges. High-carbon steel is used for springs and steel wires, while ultra-high carbon steel is called cast iron and is often used to make pots.
Primary utility wiring uses an ACSR cable, (Aluminium Conductor Steel Reinforced). The multiple strands of aluminum wires are wound around a center steel cable. The steel center is used to allow longer spans between poles or towers. Ordinary aluminum wire can not be long spanned because its weight would break the wire. All other high voltage wiring is done with different insulation thicknesses dependant upon what the voltage is. The higher the voltage the thicker the insulation. Insulation of the wires stops when the conductors carry kilo voltages usually above 5000 volts.
Steel is not used as an electrical conductor because, although it is a conductor, it's not a very good conductor -as is copper and aluminium, for example. A steel-wire core is used, however, to reinforce aluminium conductors on transmission tower lines
Steel.
Steel wiredrawing plants manufacture tie wires
There are wires that hold up the tower from underground!
London Bridge has no wires. You're probably thinking about Tower Bridge.
they are suspended from steel wires
The lack of wires and supporting devices.
copper is cheaper to manufacture and easier to bend then steel
I think copper is cheaper.
Because steel is not a good conductor of electricity. Copper is the best conductor for electricity.
Mid Steel Wires
The CN Tower utilizes several forces in its design and structure, primarily gravity, compression, and tension. Gravity pulls the tower downward, while the materials used, such as reinforced concrete and steel, are designed to withstand the compressive forces acting on them. Additionally, the structure's triangular base and guy wires help distribute loads and resist lateral forces, such as wind. Together, these forces and engineering techniques ensure the tower's stability and safety.
