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!
copper is cheaper to manufacture and easier to bend then steel
The lack of wires and supporting devices.
London Bridge has no wires. You're probably thinking about Tower Bridge.
they are suspended from steel wires
I think copper is cheaper.
Because steel is not a good conductor of electricity. Copper is the best conductor for electricity.
Mid Steel Wires
Steel wires can easily be found at any hardware store. They can also be available in the hardware department of Lowe's or Wal-mart or any other stores like that. Steel wires are good conductor of electricity and can be molded into any shape.
