OPGW cables are an important communication equipment, which requires effective lightning protection measures to ensure its normal operation and safety. The following are several common lightning protection measures and design points:
1. Install lightning rods
Lightning rods should be installed on the towers or other elevated structures where OPGW cables are installed to protect OPGW cables during lightning weather. The installation of lightning rods should comply with relevant national standards and specifications.
2. Grounding protection
All metal parts of OPGW cables (such as brackets, joints, additional equipment, etc.) should be well grounded. The grounding device should comply with relevant national standards and specifications, and should be regularly inspected and maintained.
3. Insulation protection
OPGW cables should use high-quality insulation materials that comply with national standards and specifications. During the design and installation of optical cables, the relevant specifications for insulation protection should be followed to avoid damage to the insulation materials or reduction of insulation performance.
4. System grounding
In the OPGW optical cable system, the connectivity and reliability of the system grounding should be guaranteed. The design of system grounding should comply with relevant national standards and specifications, and the inconsistency between ground and earth potential should be avoided.
5. Inspection and maintenance
For the lightning protection measures of OPGW cables, regular inspection and maintenance should be carried out to ensure their reliability and effectiveness. For any potential problems or failures, timely measures should be taken to repair or replace them.
In short, for the lightning protection of OPGW cables, multiple measures should be adopted to cooperate with each other to improve the safety and stability of the system. During the design and installation process, relevant national standards and specifications should be followed, and regular inspection and maintenance should be carried out.
