The term "ring main" initially originated in the early 20th century when electricity distribution systems underwent significant advances. It referred to a circular network of high-voltage electrical cables that were installed underground to serve large areas with electricity. The term "ring" in ring main refers to the circular or closed loop-like configuration of the cables. This loop can be opened at any convenient point to connect or disconnect the supply to properties requiring electricity. This configuration provided higher voltage and electrical efficiency, allowing for more significant distances between electricity substations, and improved reliability of the electrical supply. In summary, the word "ring main" is a technical term that describes the layout of high-voltage electrical cables installed in a circular network, providing efficient and reliable electricity distribution.
