Hot Dip Galvanized Transmission Electrical Power Pole For 69kv Electrical 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.

Our Company
Established in 1991,Jiangsu Milky Way Steel Poles is located in Wuxi,East of China ,near one of the largest sea port of China ,Shanghai,Port .
Our Products have been widely used in the power transmsion ,signal transmission and ligting for street ,road ,square ,palaestra.and so on.
We have plenty of export experience . Since our first overseas order from Pakstan in 1991 of 132 KV transmission poels ,our products have been deliveried to more than 70 contries and areas ,including America,Australia ,Russia ,Genmery ,Span,Philippines ,Malaysia , Dominica, Congo, Togo and Guniea so on.
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.
