Remark: above technical data only references for our client, we can design every type for our overseas clients.
MEGATRO is a full service engineering company with a global
reputation for delivering excellence and innovation in power
transmission, transformation, distribution, and telecommunications
systems. Our MEGATRO provide and design this type 500KV
Transmission line DFZ1 cat head type suspension tower mainly for our overseas client.
Since 2004, MEGATRO focus mainly international market and had
export many kind of transmission structures to overseas clients.
MEGATRO has been manufacturing lattice transmission tower &
tapered steel poles for lighting, traffic control, communication
and utility applications. MEGATRO pioneered the development of
transmission tower, telecom tower, substation, and other steel
structure and was also at the forefront in the design of
Transmission tower.
Over 10 years of experience and innovation in engineering, designing and building towers has evolved MEGATRO into its current form:
A complete selection of towers including self-support, lattice steel tower, monopoles and guyed towers, form custom-designed radar towers to broadcast towers and energy infrastructure. MEGATRO carries a variety of related products including fall protection, transmission lines, antennas, obstruction lights, and accessories, and other products if client need, MEGATRO also tailored product as per client condition.
MEGATRO mainly design all kinds of towers and posts for:
Our complete selection of towers includes:
MEGATRO also designs and manufactures tower related products including:
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 & angular & 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
Moreover, MEGATRO is 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
MEGATRO performs 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, MEGATRO is one of the few manufactures who assemble a face of 500KV Transmission line DFZ1 cat 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 500KV Transmission line DFZ1 cat 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. All finished surfaces shall be level and free of tears, burrs, clots and impurities.
Except otherwise specified elsewhere in the specification, the surface treatment and corrosion protection for all metal parts shall be in conformity with the latest revision of the standards listed below:
ASTM A 123 zinc (hot-dipped galvanized) coating on iron and steel products
DIN 55928 Protective painting of steel structure instructions
DIN 55945 Painting materials-Notions
DIN 18363 Paint work-Buildings
DIN 18364 Surface protection work for steel
DIN 53210 Determination of rust degree
DIN 55151 Determination of adhesion
ISO4628/3 Determination of rust penetration
MEGATRO' 500KV Transmission line DFZ1 cat head type suspension tower systems can accommodate a variety
of cross-arm. MEGATRO also offers a wide variety of accessories and
mounts.
