Prewinch was first introduced in the United States in the 1940s and 1950s. It was originally designed as a helical protection line for stress concentration and electrical corrosion and arc burn protection of naked wires. After many years of development, the Pre-winch has been widely used in transmission and distribution, fiber-optic communication, electrified railway, cable television, construction, agriculture and other fields.
