69kv Steel Electrical Power Pole For Electrical Distribution Line Project

Installation

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

assemble and installation.


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.



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.

Estbilsed  in 1989,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 and so on

To assure our products qualified ,we take steps as follows :

1. Management  team : We have employ the foreign export  to take chaege of the overall managemnt ,especailly the technical managemnt and quality management .

2. Introducing ISO management ,We are awared ISO 9001:2008 certificate . .

3. Lofting and design software :We have  transmisson power pole design software which can help us design all kinds of steel pole  ,at the same time ,the TMA and LMA are adopted by us to provide the design the drawing accuratly .

4. QC Inpection:It is our company policy that all the finish product should be inspected by our specialzed QC in every manufacure steps and beofore every shipment .

We are always persisting in horzontal cooperation with domestic senior project institute and technical colleges .The enterprise also has an highly qualified team working at R&D ,manufacure ,QC ,aftersales service and other important positions .
