catenary poles

Catenary pole refer to power transmission pole have longer conductor or steel ring to contact insulator. MEGATRO offers catenary poles in a range of lengths and sizes.  This type pole is engineered with an extremely high strength-to-weight ratio. 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. 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.

This type of pole often used in city power transmission grid, with little space, economic and lower cost. Now MEGATRO can produce distribution pole with some type as follow:

(1) Flange connection
(2) Slip joint
(2) Step type
(3) Stagger type
(4) Others
 

Pole foundation types have:

(1)        Direct embedment

(2)        Anchor bolt

(3)        Based plate

(4)        Vibratory steel caisson

MEGATRO is one of the few manufactures who assemble a face of catenary poles. This attention to quality may not be the cheapest process but it does insure every tower meets our high standards of quality. And it helps to reduce on-site construction cost due to mismatched assemblies. MEGATRO catenary poles systems can accommodate a variety of cross-arm and other accessories. After fabrication catenary poles are delivered to the galvanizing facility to be Hot DIP Galvanized. Catenary poles are processed through the facility by Caustic Cleaning, Pickling, and then Fluxing. These strict procedures insure years of maintenance free H-frame structure.

MEGATRO can optimize design, to set a compact, narrow base, the pole design not only advanced but practical, with an emphasis on economic rationality to ensure safe and reliable operation. Today, with over 10 years of experience and our commitment to excellence, MEGATRO remains an industry leader in the manufacture and design of steel tubular & monopole structures for all Highway, Municipal, Custom, telecom, lighting and electric Utility applications. MEGATRO has a complete staff of professional engineering personnel trained in the PLS Pole program and three different manufacturing processes for producing steel towers, poles and other supports. We utilize the latest versions of PLS-CADD, PLS-POLE, TOWER, AutoCAD and other CAD software. To meet the expectation, we produce shop drawings, components list and full production documentation, and even complete 3D models that facilitate the elimination of all design and drawings errors generated on the drawings. Another advantage is our 3D design and loading & design report, and can optimized the design and save cost for our clients.
