👉 "Spanless" is a concept in electrical engineering that refers to an electrical system where there are no visible connections between two conductors or components. This means that only electrical signals are transmitted and received, without any physical connection between them. The term "spanless" was first used in the 1970s by electrical engineers who were interested in developing new technologies for transmitting power over long distances. The concept of spanlessness was based on the idea that if there were no visible connections between
