400KV Four circuit transmission tower
Four-circuit transmission line belong to multi circuit which carries conductors for four circuit. For a three-phase system, this implies that each tower supports twelve conductors. In four-circuit towers the conductors are lined up vertically. Both tubular and lattice steel towers can be designed so as to support four-circuit of electrical current. Four circuits 400KV tower mainly designed as vertical phase configuration type.
MEGATRO mainly produce 400KV Four circuit transmission tower for our European clients, even some other regions or countries. Our main design engineer from USA, can use PLS 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 400KV Four circuit transmission 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. Even we take secondary finish for client again, which as duplex surface treatment. The duplex coating applied in our own paint shop.
