Professional Answer: The journey of electricity is a multi-stage process that relies on a complex network of equipment and infrastructure. It begins at a power generation plant where electricity is produced at a relatively low voltage. To be transmitted efficiently over long distances, a step-up transformer at a nearby substation increases the voltage to an extremely high level (typically 110 kV and above).

This high-voltage electricity then travels along overhead transmission lines, supported by large towers and pylons, or through underground cables in urban or environmentally sensitive areas. This is the bulk movement of power. As the electricity nears its destination, it passes through several substations where step-down transformers progressively reduce the voltage to safe levels for local distribution and, finally, for use in your home or business.

At Ningbo Changshi, we provide the essential OHTL wire cable conductor tension stringing equipment and underground cable laying equipment that make this entire process possible. Our tools and machinery are used by professionals worldwide to build and maintain the vital arteries of the modern electrical grid.
