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
Moreover,MEGATROIs fully equipped and qualified to carry out Design Engineering services which includes:
√ Overhead Transmission line steel tower & Telecom steel tower
Basic Design and Analysis
√ Shop Erection Drawings
√ as-Built Drawings
MEGATROPerforms in-house design activities specializing in electrical overhead Transmission &telecom tower steel works, which include wind and earthquake Loading, static analysis, stress analysis by finite element methods and Fatigue. Our Engineering Department is boasting of highly qualified engineering Who are conversant with international codes and standards. the work is carried Out with extensive use of CAE/CAD via a large of computer network. the computer Hardware & drafting software are liked to the CNC workshop equipment for Downloading of information thereby eliminating error and saving valuable Production time.
Besides, MEGATROis
One of the few manufactures who assemble a face of 220KV transmission
Line Z1Cat head type suspension tower.
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. after fabrication all 220KV
Transmission line Z1Cat head type suspension towers 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. MEGATRO' 220KV transmission line Z1Cat head type
Suspension tower systems can accommodate a variety of
Cross-arm. MEGATRO also offers a wide variety of accessories and mounts.
