Foreword

GB/T 17737 "Coaxial communication cables" is divided into the following sections. --- Part 1. Generic specification - General, definitions and requirements; --- Part 2. polytetrafluoroethylene (PTFE) semi-rigid insulation RF coaxial cable specification; --- Part 3. Sectional specification for coaxial cables for local area networks; --- Part 4. Sectional specification for leaky cable; Part --- Article 5. CATV trunk and distribution cable with a specification. This section GB/T Part of 417,737. This section drafted in accordance with GB/T 1.1-2009 given rules. This Part replaces GB/T 15285-1994 "leaky coaxial cable specification." This section compared with the GB/T 15285-1994, the main technical changes are as follows. --- Remove the frequency 1GHz and below the limit (see the 1994 edition of Chapter 1); --- Remove the preferred size of a predetermined nominal value of the outer diameter of the media (see 1994 edition 4.2); --- Increased cable marking and labeling requirements (see Chapter 6); --- Remove the DC resistance (when applicable) requirements (see the 1994 edition of Table 1); --- Remove the air tightness requirements (see the 1994 edition of 5.2.9); --- Remove the delivery of a predetermined length (see 1994 edition 5.3); --- Increased provisions can be integrated source measuring instruments (see Appendix A); --- Deleted based on the temperature of the attenuation constant correction provisions (see 1994 edition 6.1); --- Coupling loss measurement method (see Appendix B), the increase in the measurement and calculation of the average of three directions; the refinement of measurement Predetermined sampling point; provision "overhead laying Law" as the referee test method, and the total number of measurement points is not less than 1000 points; clear mining With "half-wavelength dipole antenna" as a standard measurement antenna, cable length is not less than 50m, ignore cable beginning and the end to 5m Within the measurement data; --- Remove the "quality assessment rules" in relation to product identification and quality conformance test (see 1994 edition, Chapter 7), change By the IEC 61196-1-1 the "ability to approve" an alternative (see Chapter 8). This section uses redrafted law reference IEC 61196-4.2004 "Coaxial communication cables Part 4. Sectional specification for leaky cable 'establishment, And IEC 61196-4.2004 is non-equivalent. Correspondence between the consistency of the standards of international documents and normative references of the following documents. --- GB/T 2423.1-2008 Environmental testing for electric and electronic products Part 2.
