How is electricity transmitted and what is the role of voltage?

2025-08-09
Electricity transmission is the bulk movement of high-voltage electrical energy from a power generation site to a substation. To minimize energy loss over long distances, electricity is "stepped up" to very high voltages (e.g., 110 kV to 765 kV) using transformers at power plants. This is because higher voltage allows for lower current, which in turn reduces the energy lost to resistance in the conductor. Once the electricity reaches its destination, it is "stepped down" at substations to lower, safer voltages for local distribution to homes and businesses. Our company manufactures the essential tools and equipment required for every step of this process, ensuring reliable and efficient power delivery.
