The height of the pre-embedded bolts of the square high pole lamp is 3m, and the m30 screw foundation pit is 1500mm deeper than the flange. 500mm. Concrete number c30. The coupling steel high pole lamp is made of 16mm rebar. A flange is added to each of the top and bottom. The size is equivalent to the flange of the pole. Pre-embedded steel bars require hot-dip galvanizing for corrosion protection. The wire pre-embedded pipe is made of Φ75 galvanized steel pipe.     After 15 days of foundation concrete pouring, it is possible to start the assembly of lamps, and the fixtures should be equipped with a 25-ton crane. In addition to the power line, the grounding resistance of the entire luminaire should be ≤4.5Ω.
