This sectional specification relates to IEC 61156-1. The cables are specifically intended for work area wiring as defined in ISO/IEC 11801. It covers individually unscreened pairs in cables for work area wiring. The cables may be provided with a common screen over the cable core. These cables are suitable for the various communication systems for which the reference is given in the appropriate detail specification. The cables covered by this sectional specification are intended to operate with voltages and currents normally adopted for communication systems. These cables should not be connected to low impedance sources, for example, the public mains electricity supply. The recommended temperature range during installation and operation may be indicated in the detail specification. NOTE 1 The nominal characteristics impedance of a cabling link, measured according to IEC 61156-1 should be 100 ?O120 O or 150 O at frequencies between 1 MHz and the highest specified frequency for the cabling category. NOTE 2 The attenuation should not be higher by more than 50 % for each respective category. NOTE 3 The resistance may be 20 % higher than the resistance of the corresponding category.
IEC 61156-3-2003由国际电工委员会 IX-IEC 发布于 2003-04,于 2008-11 废止。
IEC 61156-3-2003 在中国标准分类中归属于: K13 电缆及其附件,在国际标准分类中归属于: 33.120.20 导线和对称电缆。
