The tunnelling and underground mining industries have traditionally relied on heavy-duty rubber-sheathed cables manufactured according to DIN VDE 0250 standards. However, a significant shift is occurring as polyurethane (PUR) sheathed cables, designated with the VDE code "11Y" and "12Y" (for TPE-E variants), are increasingly specified for demanding tunnel boring machine (TBM) applications and underground operations. 隧道和地下采矿行业传统上依赖于按照DIN VDE 0250标准生产的重型橡胶护套电缆。然而，随着聚氨酯（PUR）护套电缆（VDE代码为"11Y"，TPE-E变体为"12Y"）在隧道掘进机（TBM）和地下作业等高要求应用中越来越多被指定使用，一个重大转变正在发生。
