Bitumen Galvanized Electrical Power Pole With Circuit Breaker Switch
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.

Steel
The material is in accordance with NF EN 10025 standard and NF EN 10149 standard, it has the
following property.
- Yield Strength=355 N/mm2
- Thoughness remains the same under 20 degrees below zero
- Galvanization is in accordance with NFA35503 standard class I
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.
Galvanization
The galvanization of the steel pole are under strict control. Galvanization is achieved by immersion
in a molten zinc bath(450̊) after pre-treated (dipping).
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
