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.

Ningbo's first metro line opens

CHINA: The initial section of Ningbo Rail Transit Line 1 opened to passengers at 10.00 on May 30. Line 1 is the first of five totalling 248 km which the port city in northeast Zhejiang province plans to open by 2020.

Phase 1 of Line 1 runs 20·9 km west to east from Gaoqiao West to Donghuan South Road, with 15 underground and five elevated stations. Construction began in June 2009, and required careful three-dimensional planning to allow for the area’s soft soil and the need to avoid disturbing heritage sites.

CSR Zhuzhou has supplied 22 six-car trainsets for the line, some of which were assembled locally. The air-conditioned Type B trainsets with Siemens traction equipment have aluminium bodies, LED lighting, a maximum speed of 80 km/h and a capacity of 2 062 passengers.

Trains run at headways between 7 min 15 sec and 8 min 40 sec, with an end to end journey time of 38 min.

An eastern extension of Line 1 from Donghuan South Road to Xiapu is under construction for opening in 2015, and will take the line to 46·3 km with 29 stations. Line 2 is also under construction.

Last year the National Development & Reform Commission approved a metro plan for the city which includes Line 2 Phase 2, Line 3 Phases 1 and 2, Line 4 and Line 5 Phase 1.
