It is single-circuit transmission line, and one phase carries four split conductors. These towers are made of bigger pole section, or several sections combined together. For this monopole, there are no any cross-arms, and only insulator connected and fixed at monopole itself. At both sides of monopole, one side 380kv and the other side 69kv or 138kv. This type of 380kv davit cross-arm single circuit transmission monopole Were produced and combined by solid pipe at large diameter and pole section connection as follow: (1) flange connection (2) slip joint (2) step type (3) stagger type (4) others Pole foundation types have: .Direct embedment .Anchor bolt .Based plate .Vibratory steel caisson Megatro is one of the few manufactures who assemble a face of 380kv davit cross-arm single circuit transmission monopole. 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 380kv davit cross-arm single circuit transmission monopoles 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' 380kv davit cross-arm single circuit transmission monopoles systems can accommodate a variety of cross-arm. Megatro also offers a wide variety of accessories and mounts.
