耐火电缆
摘要：
耐火中压及高压电缆(100)，包括导体(110)，相对于导体(110)布置在径向外部位置的第一半导电层(120)，相对于第一半导电层(120)布置在径向外部位置并且直接接触第一半导电层(120)的绝缘层(130)，相对于绝缘层(130)布置在径向外部位置并且直接接触绝缘层(130)的第二半导电层(140)，相对于第二半导电层(140)布置在径向外部位置的导电屏蔽(150)，相对于导电屏蔽(150)布置在径向外部位置的热阻挡层(165)，热阻挡层(165)包括由耐火或者阻燃剂层无卤材料制成的层，相对于热阻挡层(165)布置在径向外部位置并且具有朝向外的橡胶化表面的橡胶化玻璃纤维带(190)，相对于橡胶化玻璃纤维带(190)布置在径向外部位置并且直接接触橡胶化玻璃纤维带(190)的橡胶化表面的外护套(200)。
摘要（英）：

A cable includes a conductor and a first semiconductive layer arranged in a radially outer position with respect to the conductor. An insulating layer is arranged in a radially outer position with respect to the first semiconductive layer. A second semiconductive layer is arranged in a radially outer position with respect to the insulating. A conductive screen is arranged in a radially outer position with respect to the second semiconductive layer. A heat block layer is arranged in a radially outer position with respect to the conductive screen. The heat block layer includes a layer made of a fire resistant or a flame retardant halogen-free material. A rubberized glass fiber tape is arranged in a radially outer position with respect to the heat block layer. An outer sheath is arranged in a radially outer position with respect to the rubberized glass fiber tape.
