C-tracks and Ethernet? Not an Easy Combination!
The life of an Ethernet cable used in a power cable carrier is "brutal". Rapid death of the cable is frequently pre-programmed. Its no wonder: Use in cable carriers is characterised by the highest mechanical loads in terms of bending and moving in tight radii, while long travel distances, high speeds and acceleration have frequently shortened the life of many such cables significantly. For this reason, LÜTZE has developed a cable specifically engineered for cable carrier applications: The LÜTZE SUPERFLEX® ETHERNET BUS(C)PUR (4x2xAWG26). This LÜTZE Cat. 6 cable for cable carrier applications is designed for about 1 million bending cycles at a speed of up to 4 m/s. It easily handles a maximum acceleration of up to 4 m/s² and a travel distance of 10 metres. The LÜTZE cable withstands a tensile force of up to 100 N without difficulty at the minimum possible bending radius of 7.5 x D. (D = outside diameter of the cable). The material is manufactured from halogen-free and flame-retardant PU with an overall diameter of about 7.8 mm. LÜTZE SUPERFLEX® can be used in cable carriers over a temperature range of - 30 °C to + 70 °C.
The LÜTZE SUPERFLEX® contains a central cross-shaped profile that imparts high internal stability to the entire cable structure. The technical challenge here was to find a material for the cross-shaped profile that, on the one hand, had minimal effect on the reverse bending, while on the other hand still provided stability to the conductor pairs and entire cable structure.
