Hradil Spezialkabel, the specialty cable engineering firm located in the south-west of Germany, presents its high-endurance Cat. 7 hybrid cable, an extremely robust cable for indoor and outdoor applications which is also suitable for trains. The Hradil hybrid cable removes the need to have separate cables for power and signal transmission, combining both tasks in a single connection cable. Additionally, the Cat. 7 hybrid cable is suitable for indoor as well as for mechanically demanding outdoor use. This means that, with a single cable the whole train can be completely connected, even across couplers. In addition to applications such as ASDN, FDDI, ATM and Cable Sharing also high-speed applications up to 10GBase-T IEEE can be implemented. In spite of this, the hybrid cable by Hradil has an outer diameter of only 18.6 mm. It meets the exacting fire protection requirements of DIN EN 45545 as well as the Hazard Level 1-3 (HL1-3) standards. Hradil’s engineers have designed the cable to withstand extreme mechanical loads up to 10,000 Newton and for a bending radius of 10 times the outer diameter. The black high-endurance hybrid cable comes in a polyurethane outer jacket made from a halogen-free HFFR compound. Underneath this black layer there is another insulation in red. In case of excessive wear, or, if the cable jacket becomes damaged, the red colour underneath acts as a warning that the cable should now be replaced for safety reasons.
Special compounds were used for the Cat.7 high-endurance cable by Hradil with 4x(2xAWG24/19) and 16×1.5 mm². For added tensile strength, the jacket as well as the core of the cable feature aramid fibre braiding. The outer cable jacket is resistant against oil and gasoline as well as against ozone, UV, cooling fluids, lubricants and cold cleaning agents. The railway cable by Hradil excels in temperatures ranging from -40°C to +85°C.
Certified Safety for Rail Vehicles
The Cat.7 hybrid cable by Hradil meets all standards and requirements of the railway industry, such as DIN EN 45545-2 (R16-T13 HL1-HL3): fire protection in railway vehicles, IEC 60332-3-24: flame-retardant, IEC 60754-2: halogen-free, DIN 60811-2-1 Section 10: oil-resistant (168 hours at 100° C), DIN VDE 0472-6004 (flex life test), IEC 61034-2; DIN EN 50305:2003 (smoke density & toxicity); IEC 61034-2; DIN EN 50267-2-1:1999 (corrosive effects of combustion gases).
The Cat. 7 hybrid cable by Hradil meets additional standards and provisions in keeping with the requirements of EN 50288-4-2, EN 50173/Class F, ISO/IEC 11801 3rd edition 11/2017, and IEC 61156-6.
