end mast for power transmission

End mast for power transmission project

End mast also name termination pylons, uses horizontal strain insulators and occur at the endpoints of conductors. Such endpoints are necessary when interfacing with other modes of power transmission and, due to the inflexibility of the conductors, when significantly altering the direction of the tower line. Dead-end towers are also employed at branch points as branch pylons. A tower at which the power line runs further as overhead line and as underground cable is a branch tower for a cable branch.
MEGATRO is one of the few manufactures who provide end mast and assemble 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 end mast 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.
