Further, the low-carbon steel bar or iron purity that electric conductor is 0.15wt%-0.35wt% with carbon content are 99.6%-
99.8% ingot iron bar is made.
The beneficial effects of the utility model are as follows：The utility model is using the segmentation connection of multiple location steel, and crossbeam is using high
Intensity steel；Corrosion-resistant body uses structure and material two ways combination bending resistance, due to corrosion be from bottom to top, it is resistance to
Corrode and up-small and down-big truncated conical shape is used in body structure, the change in structure can significantly extend steel pawl service life；Cancel
Extra corrosion-resistant composite coating and protection ring, uses corrosion-resistant steel instead in the region that etchant gas is largely assembled, prevents sun
Pole steel pawl is corroded, and recycles and repairs simply, only needs sawing damaged location to reconnect；Electric conductor uses high conductivity steel
Material, reduces power consumption, saves electrolytic aluminium cost；Each position steel use rolled bar material, interior solid, no casting flaw, without
Seasoning metal raw material, riser-free equal loss's material, saves raw material, more environmentally-friendly；Processed by segmentation using unlike material
Shaping, while take into account and lead corrosion resistance, electric conductivity and mechanical performance, simple in structure, simplified manufacturing process, is easily promoted.
