Example 2: tested, tested, tested! Technical Data Properties CAT5 High transmission rates of up to 100 Mbit/s place high demands on the cable structure and its materials. The use of the cables in Energy Chains® subjects these materials to additional stress and results in long-lasting alterations of the electrical properties. A CF 14.02.04.02.CAT5 cable was selected as a cable to be inspected for high transmission rates. Even when subjected to an application of stress with the minimum bending radius, the cable must also be able to meet the electrical requirements of the IEC 61156-6 standard. In the case of the CF14.02.04.02.CAT5 cable, four pairs of cores are stranded with one another, with each core pair possessing a nominal cross section of 0,25 mm2. The conductor consists of bare copper wires and is surrounded by an insulation sheath consisting of foamed PE. The following items were inspected: n Characteristic wave impedance of single pairs n Single-pair attenuation n Return loss of single pairs n Near-end crosstalk attenuation of single pairs versus one another The test is to be carried out in order to determine whether the limit values of the IEC standard are complied with by the cable after being subjected to bending stress.
