Double-circuit transmission line have two circuits and hold the different conductors stacked atop one another, while in single-circuit towers the conductors are lined up horizontally. In material, it divide angular or tubular tower. Since 2004, MEGATRO begin produce every type of 110KV double circuit angular towers for both Chinese and oversea clients.

MEGATRO can optimized design and make tower less weight, high strength, proper span distance, good wind resistance, and economy in the use of materials, especially in tower design, we can make final weight lower, with maximum utility of material and make total structure more strong and sturdy. MEGATRO is equipped with sophisticated machinery and equipment for the manufacture of 110KV double circuit tower, and offers a variety of designs to meet client specific.
 
Our main design engineer from USA, can use PLS &TOWER software to design every type steel tower based on structural calculations and geometrical frame drawings. 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.

MEGATRO had professional QA &QC team to control quality and execute strict QC & QC plan as per client requirements. MEGATRO is one of the few manufactures who assemble a face of 110KV overhead transmission line steel tower.  After fabrication all 110KV double circuit transmission line steel tower, 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 is one of the few manufactures who assemble a face of every tower section. 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.

MONOPOLE
Tubular Steel Construction
Monopoles are fabricated from domestic steel, meeting or exceeding the latest EIA criteria.
Hot Dip Galvanization
Zinc coating on all hardware and components meet EIA and ASTM-A123 standards.
Wind Force
Western's monopoles are designed to withstand winds of up to 105 mph. Monopoles requiring higher or lower wind or ice loads are custom engineered.
Durable Construction
Meets heavy duty industrial applications and comes with a five-year warranty on labor and materials.
Tamper Resistant
Climbing ladder begins at 16'. Lockable access port prevents tampering. Coax, electrical power, and fiber optics are enclosed inside the structure preventing damage due to vandalism.
Ease of Maintenance
Platforms are designed for ease of access to cameras, microwave equipment, and electronics. Climbing ladder is enclosed in cage or can be equipped with an optional safety climb device.
Numerous Applications
Monopoles can be used in applications such as rail yard and intermodal facility security and in high-security areas such as prisons or defense installations. Monopoles have been used by the U.S. Border Patrol for border security.
Various Sizes, Heights, & Capacities
Please contact us with the tower requirements, and we will provide a proposal for each specific tower need.
Precision fitted connections allow quick assembly of modular sections and the top platform, sidearms or mounting frame.  Pole sections are available with identical base flange plates, allowing for simplified modifications of mounting heights and antenna reconfigurations when required.
Tapered steel poles are designed with base diameters from 2 feet to 6 feet. These minimal site requirements lower lease costs. Tapered poles can be installed quickly, while meeting the demands of GSM PCS, GSM cellular, and other applications. All poles are hot dipped galvanized for long lasting corrosion protection and with unmatched attention to detail and design, these poles offer extremely efficient strength to cost ratio.
features include:
·infinitely rotatable mounting frame or platform
·quick installations
·variety of types, for different applications
·heights in excess of 200 feet
·microwave capable
·minimal space requirements
·full line of accessories, lights and mounts

MONOPOLE TOWERS
These tube style, narrow galvanized structures offer carriers and owners numerous savings opportunities. Smaller lease areas, smaller price tags and reduced construction time offer speed to market as well as savings. These structures are manufactured in steel, concrete and fiberglass and are most often freighted on a single truck, providing additional savings. Tapered steel or slip joint poles have become the most common, with step tapered or pipe section poles as the second selection. Poles can be multi-sided or smooth.
The structures are aesthetically pleasing and blend well into the environment while requiring minimum space for installation. Interior placement of transmission lines means that the coaxial cable is not
Monopoles for Transmission
MEGATRO is equipped with sophisticated machinery and equipment for the manufacture of monopole for power transmission line project, monopole is one good choice for power transmission due to its less space, less time to install and are aesthetical in appearance, compared to conventional lattice tower. Monopole towers use a minimal space requirement, and with a solid and stable structure from which to add additional carriers. MEGATRO had produced too many type of monopole for 10KV, 35KV, 66KV, 69KV, 110KV, 220KV power transmission line project.

MEGATRO provides a monopole constructed of heavy duty galvanized steel. MEGATRO monopole systems can accommodate a variety of cross-arm with many loadings. MEGATRO also offers a wide variety of accessories and mounts. After fabrication 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 monopole has two types, one is flange connection, the other as slip type.
Features include:
·infinitely rotatable mounting frame or platform
·quick installations
·variety of types, for different applications
·heights in excess of 200 feet
·minimal space requirements
·full line of accessories and mounts

Besides conform to the drawing and design, the materials and fabrication of tower components shall conform to Chinese Standard or foreign standard.

exposed to wear and tear or wind-induced loads. Typically, climbing accessories and antennas are the only visible additions. Platforms and antenna arrays can be rotated to any azimuth.
The fastest on air times are offered by monopoles since most types can be erected in one day. Employing a minimum amount of time for foundations, a site can move quickly from "permit ready" to producing revenues. Monopoles can also be purchased with future elevation needs. Several manufacturers assemble each pole with a top flange that will accommodate growth as a standard procedure. If the rad centers of co-location tenants are known, it's advisable to provide for multiple entry ports when ordering the structure; having to cut them in later can be an expensive proposition.
If the tower structure's elevation is over 200 feet Tower Obstruction Lighting will be required to have obstruction lighting. Some structures close to an airport will require lighting no matter what height the structure is.
