In industrial cable applications involving continuous reeling and unreeling operations, cable integrity under mechanical stress is paramount. One critical structural element that ensures operational reliability is the anti-torsion braid, also known as an embedded textile mesh, positioned within the cable sheath. This technical component plays a vital role in maintaining cable performance in demanding environments such as crane systems, hoists, conveyor belts, and mobile machinery. 在涉及连续收卷和放卷操作的工业电缆应用中,机械应力下的电缆完整性至关重要。确保操作可靠性的一个关键结构元件是反扭转编织层,也称为嵌入式纺织网,位于电缆护套内。该技术组件在起重机系统、提升机、传送带和移动机械等苛刻环境中维护电缆性能方面起着至关重要的作用。
