230KV TRIPLE CIRCUIT DEAD END TRANSMISSION TOWER
MEGATRO provide 230-kV Triple Circuit Dead-end Transmission line
tower, this structure is shielded by two overhead static wires and
is a massively tall monument, rising over 120 feet. And we also can
design them as per client different requirements.
This type dead-end tower 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. MEGATRO is one of the few
manufactures who provide dead-end tower 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 230kv dead end 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.
