Caledonian Rolling Stock Cables

CABLE CONSTRUCTION

Conductors:
Tinned fine copper strands according to VDE 0295 / IEC 60228 class 5 are generally used for railway cables. For nominal cross section of over 50mmsq, 0.41mm strand wire may be used instead of 0.51mm as stipulated in IEC 60228. The IEC 60228 class 5 enhances flexibility and the ease of handling, thus lengthening the product life of the cable. These class 5
conductors are extremely flexible, and easy-to-install in the compact rolling stock environment.
Insulation and Outer Sheath:
Crosslinked polyolefine copolymer or EPR will generally be used for insulation whereas electron-beam cross-linked elastomer is employed for sheathing. Cross-linked elastomer compounds offer very good durability that can resist heat, oil, vibration, chemical aggression, etc.

Huawei and Siemens to co-operate on communications

HUAWEI: Chinese communications supplier Huawei announced on April 8 that it had reached agreement with Siemens Convergence Creators GmbH to co-operate in the development of ‘end–to-end solutions’ in the critical communications market, including rail.

Huawei says that it will draw on its expertise in GSM-R for voice communications and train control under ERTMS, as well as enterprise LTE and broadband radio trunking for voice and data. Siemens CVC will bring its experience of delivering large-scale transport projects as well as GSM-R, and its existing laboratory in Croatia is to be equipped with Huawei technology to undertake integration testing of GSM-R and other railway-specific products.

David Xu, Vice-President, Wireless Products, at Huawei Enterprise, said that the facility would enable end–to-end solutions to be ‘integrated seamlessly in a safe and professional operations environment’. Bernard Payer, Senior Vice-President, Infrastructure & Security, at Siemens CVC, looked forward to demonstrating to customers that ‘smart railway projects can be delivered safely and flexibly within a short time frame’.

One key project will be pre-integration testing of GSM-R equipment for Etihad Rail in the United Arab Emirates, where Huawei is supplying its technology for a new national rail network totalling 1 200 km.
