Specifications
Product Overview
| Suitable Applications | WTB (wire train bus) data cable for fixed and protected installations inside of rail vehicles. This cable is applied for digital signal transmission with good transmission rate at the high frequencies and capable to continue transmitting data even when being directly attacked by fire. It is suitable for wiring of the components of communication network (TCN) over the entire trainset. This cable meets the requirements of the relevant parts of international railway standards like EN 50305, EN 50267, EN 45545-2, IEC 60331-23, EN 50200, IEC 60332-3-25 Category D and TJ/CL-313. |
