China's High-Speed Trains Using Huber+Suhner Coax Cable

Huber+Suhner has supplied a range of radio-frequency coaxial cables for the new passenger entertainment system on some of China’s most prestigious high speed trains. Passengers on the CRH380 type high-speed trains on the Shanghai-Hangzhou and Beijing–Shanghai lines can watch movies and participate in online gaming while their carriages reach speeds of up to 350 kilometres per hour.

Changchun Railway Vehicle Co. and Tangshan Railway Vehicle Co. are equipping a total of 100x8 train units (800 carriages) on these high-speed trains with passenger entertainment systems. Huber+Suhner has delivered 10,000 metres of GX07272 coaxial cable to connect the systems. This was routed through all the carriages as a backbone cable in order to transmit the data through the entire train. In addition, 200,000 metres of GX03272 and GX4273 cable were installed to serve as network cables for the individual devices in each car.

The Huber+Suhner coaxial cables are resistant to temperature. In addition, they are halogen-free and offer flame resistance with minimal smoke development. The cables also guarantee reliable signal transmission even when subjected to constant vibrations, knocks and impacts. Due to these properties, coaxial cables from Huber+Suhner are ideal for use in trains, and were therefore the customers' first choice.

Thanks to the new entertainment system with cables from Huber+Suhner, passengers can now watch movies or play games on the trains to help pass the time.
