Detailed Description

High voltage AC transmission towers (HVAC TOWER) In the power transmission line project, high voltage refer to 35 to 220KV, but in china it refer to 10KV, 35KV, 66KV, 110KV, 220KV. Three-phase electric power systems are used for high voltage (66- or 69-kV and above) and extra-high voltage (110- or 115-kV and above; most often 138- or 230-kV and above in contemporary systems) AC transmission lines. The towers must be designed to carry three (or multiples of three) conductors. The towers are usually steel lattices or trusses, hence the name of High voltage AC transmission towers. Some high voltage circuits are often erected on the same tower as 110 kV lines. Paralleling circuits of 380 kV, 220 kV and 110 kV-lines on the same towers is common. Sometimes, especially with 110 kV circuits, a parallel circuit carries traction lines for railway electrification MEGATRO is one of the few manufactures who assemble a face of every HVAC 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 HVAC 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's HVAC TOWER systems can accommodate a variety of cross-arm. MEGATRO also offers a wide variety of accessories and mounts. Availability size: Based on the customer’s requirements.
