Professional Answer: The journey of electricity from a power plant to your home involves several stages. First, transmission lines carry high-voltage power from the plant to a substation. At the substation, transformers "step down" the voltage to a lower level. This lower-voltage electricity is then carried by distribution lines along streets and neighborhoods. A final transformer, often mounted on a utility pole, reduces the voltage one last time before the power enters your home through a service drop. Our company provides essential equipment for every step of this process, including stringing equipment for the overhead lines and specialized tools for underground cable laying.
