The journey of electricity is a four-stage process that forms the foundation of the modern electrical grid: generation, transmission, distribution, and consumption. It begins at a power plant, where electricity is produced. To minimize energy loss over long distances, transformers at the transmission substation "step up" the voltage to an extremely high level. This high-voltage electricity is then carried over vast distances by transmission lines, typically supported by tall towers.

Upon reaching a local area, the electricity arrives at a distribution substation, where another transformer "steps down" the voltage to a safer, more manageable level. From there, it is sent through distribution lines (the poles and wires you see in neighborhoods) and eventually to transformers on poles or pads near homes and businesses, where the voltage is lowered one last time for safe use.

As a manufacturer of specialized tools and equipment, Ningbo Changshi plays a critical role in every step of this process, from installing the high-voltage transmission lines to laying the underground cables that deliver power to our customers' doorsteps.
