138KV single circuit single pole Y-frame structure
A single-circuit transmission line carries conductors for only one
circuit. For a three-phase system, this implies that each tower
supports three conductors. In single-circuit towers the conductors
are lined up horizontally. Single-circuit towers hold the different
conductors stacked atop one another, while in single-circuit towers
the conductors are lined up horizontally. For 138KV monopole, we
can design and produce them as Y-frame structure. It looks like
character "Y", and when installed, the structure tubes outward, and
creates a Y shape, which is also one type steel lattice power
tower, apparently carrying 138 kV, even higher voltage power
transmission line, are used in high voltage AC and DC power
transmission line systems as well as railway traction, and come in
a wide variety of shapes and sizes.
These 138KV single circuit single poles can be manufactured as one
large piece, or as several small pieces which fit together. This
type of pole often used in city power transmission grid, with
little space, economic and lower cost. Now MEGATRO can produce
distribution pole with some type as follow:
(1) Flange connection
(2) Slip joint
(3) Step type
(4) Stagger type
(5) Others
MEGATRO can optimize design, to set a compact, narrow base, the
pole design not only advanced but practical, with an emphasis on
economic rationality to ensure safe and reliable operation. Today,
with over 10 years of experience and our commitment to excellence,
MEGATRO remains an industry leader in the manufacture and design of
steel tubular & monopole structures for all Highway, Municipal,
Custom, telecom, lighting and electric Utility applications.
MEGATRO has a complete staff of professional engineering personnel
trained in the PLS Pole program and three different manufacturing
processes for producing steel towers, poles and other supports. We
utilize the latest versions of PLS-CADD, PLS-POLE, TOWER, AutoCAD
and other CAD software. 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 is one of the few manufactures who assemble a face of 138KV
single pole. 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. MEGATRO 138KV single poles systems can
accommodate a variety of cross-arm and other accessories. After
fabrication 138KV single poles 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.
