In order to maintain general safety of passengers, the requirements of cables in rail vehicles have always been very high.

The new European Standard DIN EN 45545-2 goes on to increase the requirements regarding fire protection in rail vehicles. Besides being halogen free, all used cables have to be flame retardant and self-extinguishing, and are not allowed to contribute to fire propagation.

Application fields

SAB Bröckskes Ethernet cables, of the categories five, six and seven, have proved best performance in practise under harsh environmental conditions. Due to the current and future development in automation and rail industry and the steadily increasing data volumes and rates, the cable manufacturer SAB Bröckskes (Lower Rhine) now offers the new rail FRNC cables accordant to DIN EN 45545-2, especially for rail industry.

The new cable type, according to the latest standard CATLine CAT 5e R, CAT 6A R, and CAT 7A R, completes the product range of the cable specialist and enables a wiring accordant to the highest current safety standard of the rail industry.
