Over the past two decades, the cable industry has witnessed a fundamental transformation in safety requirements for confined space installations, particularly in tunnels, underground transit systems, and mining operations. At the center of this evolution lies the shift from traditional halogenated flame retardant cables to halogen-free, low-smoke alternatives. 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。
