Development and Evaluation of Fire Resistant Railway Signalling Cable

Abstract

The railway signalling cable is designed for remote control and teletransmission in underground railway networks. It is very critical situation that the railway signalling cable continues to transmit data in the event of a fire. In this study, the fire resistant test performance of railway signalling cable has been developmented and evaluated via experimental research. A standard railway signalling cable generally consists of conductor, insulation, laying-up, wrapping, screen, inner sheath, armour and outher sheath. The mica tape was added as one layer with 30% overlapping to produce desired fire resistant cable. First step, the railway signalling cable produced used only mica tape used, results show that the cable with mica tape is successful at 110 V. Also, it is not bad for the 250V as it seen the test results. After having non satisfied results, glass tape was added additionally over inner sheath (instead of PP tape) for better results for higher voltage values. After redesign of the cable with addition of glass tape over inner sheath, better results were expected but the results were not as good as expected. Only at 250V appropriate results were achieved according to both IEC 60331 – 21 & 60331-2 standard. When we examined the situation, we saw that the cable was flattened a bit after the new-design. Then, the re-production of the new design cable (mica + glass tape) is been planned without any rework process. All results show that the new design railway signalling cable is resistant to fire tests according to IEC 60331-21, IEC 60331-1&2 up to 1000V as shown in the paper.
