This section GB/T 18015 Part 8.

This section drafted in accordance with GB/T 1.1-2009 given rules.

This section uses the redrafted law to amend the use of IEC 61156-8:2013 "digital communication with twisted or twisted multi-core symmetric cable No. 8 Part 2. Workstation wiring cables with symmetrical pair or twisted pair cables of 1200 MHz and below transmission characteristics ".

This part of the structure compared with IEC 61156-8:2013 compared to more adjustment, Appendix A lists this part and IEC 61156-8.

2013 reg number control list.

This part of IEC 61156-8:2013 technical differences and the reasons are as follows.

--- Modify the reference color insulation documents, the "insulation color should be consistent with the requirements of IEC 60304" be amended to "Insulation color should be consistent with GB/T 6995.2 requirements ", priority reference to national standards and GB/T 6995.2 provisions of the insulation chromatography color and IEC 60304 is consistent (see 5.2.2, IEC 61156-8, version 5.2.2, 2013);

--- Increasing the coupling attenuation test method; the original text only specifies the absorption clamp method, according to China's actual application, an increase of three Coaxial method (see 6.2.8, version 6.2.8 of IEC 61156-8, version 2013).

This section made the following editorial changes.

--- Modify the insulation resistance unit, 5000Mohm · m to 5000Mohm · km (see 6.2.4,2013 version of IEC 61156-8 of 6.2.4);

--- Replace a large number of suspension in the original text to "general requirements";

--- Suspended section "transmission performance test cable length requirements" adjusted to the general requirements (see 6.1,2013 version of IEC 61156-8 6.3);

--- 6.3.11 return loss in the frequency range 1MHz ~ 1200MHz to 4MHz ~ 1200MHz, and Table 4 to maintain Consistent (see 6.3.11, version 6.3.11 of the 2013 IEC 61156-8);

--- The original "cable impact test, crash test, vibration test, insulation heat aging after the winding test, high temperature stress test jacket Test, thermal shock test, steady-state damp heat, salt spray and sulfur dioxide test, immersion "is not applicable to the deletion of this section (see 2013 version IEC 61156-8, 6.4.13, 6.4.14, 6.4.15, 6.5.2, 6.5.6, 6.5.8, 6.5.9, 6.5.12, 6.5.13).

This part is proposed by China Electrical Equipment Industry Association.

This part of the wire and cable standardization Technical Committee (SAC/TC213) centralized.

1 Scope

GB/T 18015 provisions of this section 1200MHz and below transmission characteristics of twisted pair or twisted symmetrical cable installation conditions, timber Materials and Cable Structure, Performance and Requirements.

This section applies to GB/T 18233 and ISO/IEC 15018 defined in the buildings, equipment and work area used in the cable, up to Four pairs of cables can be used at the same time. The cable structure is 4 pairs of separate shielding pairs. The total shielding can be covered outside the cable core.

Note The cables specified in this standard apply to the voltage and current specified in the communication system and should not be used on low impedance power supplies such as public power supply systems.

This section GB/T 18015.1-2017 together with the use.
