A series of new synthetic armored cables were developed and tested to ensure that they were suitable for use with the RECoverable Autonomous Sonde (RECAS), which is a newly designed freezing-in thermal ice probe. The final version of the cable consists of two concentric conductors that can be used as the power and signal lines. Two polyfluoroalkoxy jackets are used for electrical insulation (one for insulation between conductors, and the other for insulation of the outer conductor). The outer insulation layer is coated by polyurethane jacket to seal the connections between the cable and electrical units. The 0.65 mm thick strength member is made from aramid fibers woven together. To hold these aramid fibers in place, a sheathing layer was produced from a polyamide fabric cover net. The outer diameter of the final version of the cable is ~6.1 mm. The permissible bending radius is as low as 17–20 mm. The maximal breaking force under straight tension is ~12.2 kN. The cable weight is only ~0.061 kg m−1. The mechanical and electrical properties and environmental suitability of the cable were determined through laboratory testing and joint testing with the probe.

用于冷冻热冰探头的新型合成纤维铠装电缆

开发并测试了一系列新型合成铠装电缆,以确保它们适合与新设计的冷冻式热冰探头 RECoverable Autonomous Sonde (RECAS) 一起使用。电缆的最终版本由两个同心导体组成,可用作电源线和信号线。两个多氟烷氧基护套用于电绝缘(一个用于导体之间的绝缘,另一个用于外导体的绝缘)。外绝缘层涂有聚氨酯护套,以密封电缆和电气单元之间的连接。0.65 毫米厚的加强件由芳纶纤维编织而成。为了将这些芳纶纤维固定在适当的位置,用聚酰胺织物覆盖网生产了一个护套层。最终版本电缆的外径约为 6.1 毫米。允许的弯曲半径低至 17–20 mm。直线张力下的最大断裂力约为 12.2 kN。电缆重量仅为 ~0.061 kg m-1. 通过实验室测试和与探头的联合测试确定电缆的机械和电气性能和环境适用性。
