Core changes in the standard revision
Technical elements Requirements of the 2017 version Changes in the 2022 version Material for power cables Not specified Added requirements for selection of insulation and sheath materials (5.8.4) Optical cable laying Static bending radius Added requirements for dynamic bending radius (7.2.4) Cultural heritage protection projects General requirements Added special laying requirements (7.12.3)
Analysis of key technical requirements
Cable selection specifications
Chapter 5 of the standard clarifies three core selection principles:
- Environmental adaptability: Select the control cable sheath material according to the humidity, temperature and corrosion level of the laying site
- Transmission performance: Data cables must meet the bandwidth requirements of 100MHz and above
- Fire protection level: Flame-retardant comprehensive cables are mandatory in crowded places
Main points of laying process
Typical scenario implementation case
In the museum security renovation, it is necessary to implement the following at the same time:
- Use Low smoke zero halogen cable meets the fire protection requirements of cultural relics protection units (7.12.3)
- The video surveillance cable and lighting line maintain a distance of ≥300mm (6.3)
- The pipe groove filling rate does not exceed 40% (6.4)
Inspection implementation guide
Inspection stage Test items Technical indicators On-site inspection Cable identification Comply with GA/T 1297-2021 Laying acceptance Bending radius ≥8 times the cable diameter (6.5) Transmission test Attenuation value ≤Appendix A limit
Standard Evolution Analysis
This revision reflects three major technical trends:
- Intelligent adaptation: New bus-type cable connection specifications support the access of IoT devices
- Security enhancement: Refinement of lightning protection and grounding requirements (referenced GA/T 670)
- Project traceability: Improve the inspection record system (Chapter 10)
