138KV Lattice Towers for Power transmission
MEGATRO have a standard range of Lattice Towers to all our customers, which have three-legged, four-legged or every types to serve single circuit, double circuit, multi circuit, substation steelworks and other application. Especially for 138kv lattice tower for our overseas clients, MEGATRO manufacture various types of 138KV Lattice steel Towers from slender single user options to large multi user switch structures. The types of construction fall into three broad categories; Angle Tower, Solid Rod Tower and Tubular Tower.
Our 138KV lattice towers typically provide a more flexible solution compared to monopoles. Some of the benefits are the easy addition of additional antennas, flexibility in the feeder installation and good access to the telecoms equipment.
lattice angular or tubular towers are ideal when you have a requirement to support large equipment loads at high levels. Made from structurally efficient tubes, the towers can be hand built and have a wide range of cross-arms, mountings and other accessories are available. We can provide these towers at various heights up to 240 meters depending on the location.
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.
