Cable crushing represents one of the most insidious and costly failure modes in reeling cable systems for container handling cranes, mobile equipment, and industrial material handling applications. When we speak of cable crushing in the context of drum winding systems, we are describing a progressive mechanical failure that occurs when cables wound onto a drum at high tension are later compressed by additional cable layers wound at even higher tension. This creates a compound crushing effect where the inner layers experience compressive forces far exceeding what the cable construction was designed to withstand. Understanding how to prevent this failure mode through proper tension management is essential for ensuring reliable, long-term operation of (N)TSKCGEWÖU cables in demanding crane applications. 电缆挤压代表了集装箱处理起重机、移动设备和工业物料搬运应用中卷筒电缆系统最隐蔽且代价最高的故障模式之一。

This technological transition represents more than just a materials change—it reflects a deeper understanding of fire safety dynamics and the true risks that cable fires pose to human life, critical infrastructure, and emergency response operations.1 在过去的二十年中，电缆行业在密闭空间安装（特别是隧道、地下交通系统和采矿作业）的安全要求方面发生了根本性的转变。这一演变的核心是从传统的卤化阻燃电缆向无卤、低烟替代品的转变。
