[0002] A complete lightning protection system includes lightning rods, down conductors and grounding devices. Down conductors refer to metal conductors that connect lightning rods to grounding devices. Down conductors of lightning protection devices should meet the requirements of mechanical strength, corrosion resistance and thermal stability, and provide a good grounding path for the large currents that lightning rods bear. Grounding wires are mainly arranged around buildings and in some of the middle columns.

[0003] The existing lightning protection grounding down conductor structure is in the shape of a T-shaped connection crimping tube, which is vertically connected and fixed by a transverse steel pipe and a longitudinal steel pipe, and the internal grounding body is fixed by hydraulic crimping in order to avoid sparks generated by welding. However, the right angle of the T-shaped connection crimping tube is not independently supported, which makes the bending resistance of the lightning protection grounding down conductor structure poor. After long-term use, the connection between the transverse steel pipe and the longitudinal steel pipe is prone to cracks due to bending, thereby shortening the service life of the T-shaped lightning protection grounding down conductor structure.

[0004] In summary, the utility model therefore provides a down conductor structure for lightning protection and grounding to solve the above problems. Utility Model Content

[0009] Furthermore, the fastening screws are in contact with the rubber pads, and the angles between the reinforcing plate and the transverse steel pipe and the vertical steel pipe are all 45°.
