The mast with the height of 20 – 50m with supporting arms, mounted ceramic insulator for power transmission wire
Lighting frame up and down with blocking mechanism making lightings more stable and user safer.
The materials, used for manufacturing pole, suitable for the standard of Viet Nam, re-tested by Directorate for Standards and Quality & Testing center 3 and Center of Testing Materials – University of Technology – Ho Chi Minh City .
For the pole with the height below 12m is welded one generating line and along the length of pole by submerged arc welder (without horizontal weld of pole-body).
In oder to avoid being inoxible, the pole is protected by hot-dip galvanization with the standards of 18TCN-04-92. After hot-dip galvaned, the pole electrostatic painted or paint oil with 2 components
