Quadruple and three-roll refers to a special type of wiring method, which is usually used for line crossing in buildings or other environments where pipeline layout is complicated. Specifically, it threads the wires in four directions and then rolls up the three cables so that only one cable remains, which saves space and reduces the complexity of wiring. Four-in-one three-volume devices are widely used in fields such as electric power, communications, and networks, and can greatly improve work efficiency. In addition, the four-part three-volume series is also widely used in the fields of calligraphy, poetry, articles, calligraphy and painting, etc. It can show the rich layers and perfect structure of the work, allowing readers to better appreciate the beauty of the work.
