The requirements for the testing specifications of building lightning arresters are as follows:
1. Check the material specifications (including diameter, cross-sectional area, thickness), support card spacing, welding process with the down conductor, anti-corrosion measures, protection range, lightning grid size, and safety distance between the lightning arrester and the protective object. The material specifications and installation process of the lightning arrester should comply with the requirements of Table B1 in Appendix B 2. Check the appearance of the lightning arrester, and there should be no obvious mechanical damage, fracture, or serious rust 3. Check if there are any other electrical and electronic circuits attached to the lightning arrester. The attached electrical and electronic circuits should be directly buried in soil with metal protective cables or wires threaded into metal pipes. The metal protective layer or metal pipe of the cable should be grounded, and the length buried in the soil should be at least 10m before it can be connected to the grounding of the power distribution device or to the power cord or low-voltage distribution device
