The size of the square copper braided tape used for lightning protection of glass curtain walls depends on the specific size, design, and requirements of the curtain wall, as well as the specifications and requirements of the lightning protection system. Generally speaking, copper braided tapes for lightning protection should be selected based on the following factors:
1. The area and height of the curtain wall: Larger curtain walls may require larger copper braided tapes to ensure sufficient grounding and lightning protection effects.
2. Lightning protection system specifications: According to the level and design standards of the lightning protection system, copper braids of appropriate size are required to meet the requirements.
3. Environmental conditions: Considering environmental factors such as climate, salt spray, etc., more corrosion-resistant materials and larger sizes may be required.
4. Regional lightning activity frequency: Some areas may be more susceptible to lightning attacks, so larger copper braids may be needed to provide better lightning protection.
Generally speaking, it is recommended that you consult a professional lightning protection system engineer or supplier, who will provide you with appropriate recommendations and specifications based on your specific needs and circumstances. The size of copper braided tape should comply with relevant national or regional standards and specifications.
