Poles up to 3,000mm pole diameter can be manufactured using Automated Submerged Arc Welding and Automated MIG/MAG Welding Machineries, LVD bending machinery which is capable of bending up to 20mm plate thickness, Plasma cutting technology under water up to 35mm thickness and Oxy-cutting technology up to 100mm plate thickness.
All manufacturing processes according to ASCE Manual 72 are strictly controlled by highly trained, experienced and certified quality inspectors of Mita? Poles having Liquid Penetration, Magnetic, Ultrasonic and Radiographic NDT testing level II.
All poles are represented by using symbols.
The symbol for each pole defines pole type and top load.
Example : A distribution pole having 11m height and 1,500kg top load is represented by the symbol ;
EDH - 11 - 1500
EDH : Power Distribution Line pole
Height : 11m
Top Load : 1,500kg
