Before electricity can arrive at your home to toast your bread it has to be made first. Electricity is made or generated at power plants basic source is used to make electricity can be coal, water, natural gas, oil, nuclear and wind. When electricity leaves the power plant it is in its most powerful form or as high as seven hundered sixty five thousand Volts. To compare when it gets to your wall outlet it is just 120 or 240 volts from the power plant.
Transmission lines carry electricity long distances from city to city or from state to state and these lines are help up and lindked together by transmission towers whicha are the big structures you’ve probably seen along the highways. These towers are usually about 100 feet tall and can be made of either metal or wood. Now transmission lines are actually bare aluminum or copper which are conductors for the electricity transmission wires ar larger than the wires and poles in your neighborhood. Porcelain insulators hold the wires in place and keep the electricity running through the wores and not throught the tower itself and remember a conductor allows for the easy flow of electricity and an insulator protects or does not allow for the easy flow of electricity in addition to the wires carrying the electricity one or two ground wires protect the town from lighnting strikes these bare wires are not safe to touch at any time you should never touch climb or go near the tower wires before electciry can travel from the transmission systems and be delivered to your home it has to make a stop at a substation which is a transformer. Electricity is easier to handle and is now ready to be delivered to your home or business
