Transposing Tower

Transposing tower for power transmission line project A tower in which the conductors exchange positions in order to balance the capacitance and impedance of the conductors, this tower named transposing tower. That is to say, In electrical power transmission, a Transposing tower is a transmission tower that changes the relative physical positions of the conductors of a transmission line. For example, a section of a line may be (top-to-bottom) phases A-B-C on the left, also phases C'-B'-A' on the right. The next section may be B-C-A on the left, also A'-C'-B' on the right. A Transposing tower allows these sections to be connected together, while maintaining adequate clearance for the conductors. This is important since it balances electrical impedances between phases of a circuit. 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. After fabrication all 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's Transposing 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.
