138kv 25ft Galvanized Electrical Power Pole For Overheadline Project

 

Excellent performance

 

Because of the long and thin shape, closed polygonal section and apply of high strength steel material, these steel poles have excellent durability. They can withstand the extreme condition, such as the frost climate, unbalanced loads, or breaking of wire.

 

 

Installation

 

The designing weight of the steel poles are usually relatively light and is good for the operation, transportation, assemble and installation.

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

 

 

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.
