220kv Q345 galvanized electrical power pole for electric line


Mechanical Property


The metal supports are designed to withstand the nominal force F and the pressure of the wind V applied at 0.25m from the top. Under these loads, the safety factor with respect to the elastic limit of the steel is larger than 1.8. The post also resists a torque equal to (F+V) ×1m. Tests shows the load intervened when breaking is around 2 times of design load.


Galvanization


Standard: NFA91121

Average thickness of the galvanization: Not less than 70



Maintenance


The hot dip galvanization treatment can increase the service life of the steel pole without the environmental pollution and no need for other daily maintenance. The following described types are specially designed for Africa Market which can meet the regulated height and load standard of France electricity power company.


Production


Our steel pole is bent to form to the polygonal (conical) section firstly. Then it is welded by the automatic submerged-arc. Then it is welded by the automatic submerged-arc welding machine.


Thirdly the top cap, strip and base plate will be welded to the pole. And finally other accessories (support brackets, ladder support, etc.) will be welded to the pole shaft.



Manufacturer Tolerance


- Component Length: -25mm to 75mm

- Straightness: 2mm/m

- Twisting degree: 1̊ per 3 meters length

- Ovalisation : Maximum is 3%

- The average diameter : +/-0.5%

-Slip length: +/-150mm
