Poles fine coarse application of this feature is the strength of the rod and the like. Such poles on the fine-coarse hollow structure at its carrying capacity to meet the prerequisite 8 m prestressed electric pole, saving material 8 m prestressed pole prices, reduced weight, reduced cost. Wire rod hollow structure while improving its stability. Comparison of hollow circular cross section with a solid circular cross section, if they are cross-sectional area equal to the radius of the ring and the inertia moment of inertia I i cross section is much larger than the solid circles. Thus the stability of quality 8 m prestressed pole, is much greater than the stability of the hollow rod of a solid rod. Pole foundation pit should be consistent groove: groove pit length, width and depth dimensions shall comply with the design requirements, its tolerance are ± 50mm. In the longitudinal direction of the pit straight rod groove should be parallel with the road side stone; in the longitudinal direction of the curve should be perpendicular to the rod groove pit and force direction of the force. Poles cast foundation or basis of the outer edge of the chuck and other facilities shall comply with the provisions of the minimum distance. Former tank pit excavation, shall be approved by the management unit rod pit near the municipal facilities approved. 8 m prestressed pole manufacturers _ _ Hebei 8 m prestressed pole tower provided by Kyushu Electric Power, Kyushu Electric Power Tower Henan limited liability company.
