330KV Y type single circuit transmission pole

330KV Y type single circuit Transmission pole
This photo refers to our 330KV Y type single circuit transmission pole, it is single circuit pole structure. On the tope of H pole, it is OPGW or OHGW. This type structure looks like letter “Y” and named Y type transmission pole, which is made by two same size pole and connected by flange together.  
Since 2004 MEGATRO being to produce and design every type of steel poles and lattice towers for overseas client in utility electricity, telecom and other application. These 330KV Y type single circuit Transmission pole structures can be manufactured with some type as follow:
(1) Flange connection
(2) Slip joint
(3) Step type
(4) Stagger type
(5) Others 
 
 MEGATRO can optimize design, to set a compact, narrow base, the tower 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. 
The structure shall be designed according to load combinations given as per IEC 61936-1 and as illustrated below:
Normal loads
1 Dead weight load
2 Tension load
3 Erection load
4 wind load
 
Exceptional loads
1 Switching forces
2 short-circuit forces
3 Loss of conductor tension
4 Earthquake forces

MEGATRO is one of the few manufactures who assemble a face of 330KV Y type single circuit Transmission pole and lattice towers. 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 330KV Y type single circuit Transmission pole can accommodate a variety of cross-arm and other accessories. After fabrication all 330KV Y type single circuit Transmission poles are delivered to the galvanizing facility to be Hot DIP Galvanized. Towers are processed through the facility by Caustic Cleaning, Pickling, and then Fluxing. These strict procedures insure years of maintenance free towers. Even we take secondary finish for client again, which as duplex surface treatment.
