What is the fundamental difference between a transmission line and a distribution line?
2025-08-12
Answer: While both are essential parts of the power grid, transmission lines and distribution lines serve very different functions. transmission lines carry large amounts of electricity at extremely high voltages over long distances, typically from power plants to substations. They are often characterized by their tall steel towers and thick, bundled conductors.
In contrast, distribution lines take electricity from substations and deliver it at lower voltages to end-users, such as homes and businesses, over shorter distances. They are the familiar lines we see on shorter wooden poles in neighborhoods or buried underground.
Our company, Ningbo Changshi, provides the specialized tools and equipment for both segments. Our OHTL tension stringing equipment is used to install and maintain the robust, high-voltage transmission lines, while our underground cable laying equipment is crucial for building the safe and reliable distribution networks that power our daily lives.
