These strict procedures insure years of maintenance free H-frame structure. Catenary poles are processed through the facility by Caustic Cleaning, Pickling, and then Fluxing. After fabrication double circuit catenary poles are delivered to the galvanizing facility to be Hot DIP Galvanized. MEGATRO double circuit catenary poles systems can accommodate a variety of cross-arm and other accessories. And it helps to reduce on-site construction cost due to mismatched assemblies. This attention to quality may not be the cheapest process but it does insure every tower meets our high standards of quality. MEGATRO is one of the few manufactures who assemble a face of double circuit catenary poles. Now MEGATRO can produce distribution pole with some type as follow: This type of pole often used in city power transmission grid, with little space, economic and lower cost. In general, this type of pole fabricated with mild steel or high strength steel, such as ASTM A36, ASTM A572 GR50, GR65, Q235B, Q345B, S355JO, S355JR, ST37, ST52, BS 50B or other. The poles can be quickly deployed with minimal hardware and labor, factory drilled to customer specifications or modified in the field, if required, using a carbide-tip bit. This type pole is engineered with an extremely high strength-to-weight ratio. MEGATRO offers catenary poles in a range of lengths and sizes. This type poles are mainly used in city grid project, and widely used in oversea regions. Usually both circuits operate at the same voltage. Double circuit catenary pole structure refers to one single pole to carry double circuit transmission line, which has two circuits.
