Several hundred kilometres of safety cable, as well as system components made by Datwyler Cables, have been installed in the five motorway tunnels of the West Bypass at Zurich. The safety cables, with extended insulation and functional integrity (FE 180/E30-E60) contribute to the reliable function of the aeration, ventilation, signalling and lighting.Since 2007, Datwyler Cables delivered copper and fibre-optics cables, as well as the corresponding components, to several working committees and manufacturers of circuits in the frame of the construction. The pre-tested systems made by Datwyler Cables fulfil the European guidelines and guarantee high system availability, even in case of a fire.
