同轴通信电缆.第4部分:辐射电缆分规范

[中文适用范围]： 本部分IEC 61196适用于辐射同轴通信电缆。这些电缆用于无线通信系统，如隧道、铁路、高速公路、地铁、电梯和其他传统天线传输不令人满意甚至不可能的场所。 应与IEC 61196-1:2005一起阅读 本部分IEC 61196适用于辐射同轴通信电缆，并规定了术语和定义、材料和结构、IEC类型名称、标准额定值和特性、识别、标记和标签、成品电缆的要求、质量评估、交付和储存等。辐射同轴通信电缆广泛应用于无线通信系统中，适用于长、窄、半封闭和室内环境，如高速铁路、地铁、隧道和室内环境。 [外文原描述]： IEC 61196-4:2022 CMV contains both the official standard and its commented version. The commented version provides you with a quick and easy way to compare all the changes between IEC 61196-4:2022 edition 4.0 and the previous IEC 61196-4:2015 edition 3.0. Furthermore, comments from IEC SC 46A experts are provided to explain the reasons of the most relevant changes, or to clarify any part of the content. IEC 61196-4:2022 applies to radiating coaxial communication cables, and specifies the terms and definitions, material and construction, IEC type designation, standard rating and characteristics, identification, marking and labelling, requirements of finished cables, quality assessment, delivery and storage, etc. This fourth edition cancels and replaces the third edition published in 2015 This edition includes the following significant technical changes with respect to the previous edition: a. rewrote "1 Scope" to be consistent with other blank detail specifications of coaxial cables; b. updated different standards in "Clause 2 Normative references"; c. added the definitions of uniformly radiating type cable, stop frequency band and link loss; d. added different materials and constructions in 4.2 to 4.5; e. added "Clause 5 IEC type designation"; f. added a detailed rated temperature range of different materials in "6.2 Rated temperature range"; g. added detailed frequencies in "6.3 Operating frequency range"; h. added "6.4 Stop frequency band" and "6.5 Radiating characteristics"; i. added different detail requirements or typical values in 8.2.4, 8.2.7, 8.2.8, 8.4.3 to 8.4.8; j. deleted "7.4.4 Ovality of outer conductor"; k. added "8.2.11 Link loss", "8.4.9 Adhesion of dielectric", "8.4.10 Shrinkage for insulations", "8.4.11 Maximum pulling force of cable"; i. used IEC 61196-1-123 and IEC 61196-1-124 in the electrical requirements to replace Annex A and Annex B respectively and deleted Annex A and Annex B; m. added "Figure A.1 Example of testing coupling loss around circumferential orientation of radiating cable (Y-Z)" in Annex A.
