General
Information
Highlight
has designed and developed tapered tubular steel pole structure for
electrical distribution and transmission line with hot-dip
galvanization of more than 50 years service. The poles have been
tested and approved by Steel Tower Inspection and Testing Center of
the Ministry of Power Industry and other international testing
institutions.
These
masts are continuous tapered polygonal cross section mono-tubular
structures manufactured from press steel welded longitudinally. To
meet specific conductor height and masts may consist of more than
one section to be assembled on site with telescoping splices
jointing section.
Advantages
of Tapered Galvanized Steel Distribution Poles
A New Choice: As
a direct substitute for wood, tapered galvanized steel distribution
poles are designed to carry conductors and equipment for electrical
distribution, light duty transmission, and telephone, cable, and
other telecommunication facilities. Tapered Galvanized steel
distribution poles withstand atmospheric and environmental rigors
much better than wood.
Corrosion Protection: Zinc
protects steel from corrosion. The reason for the extensive use of
galvanizing is the two-fold nature of the coating. As a barrier
coating, it provides a tough, metallurgically bonded zinc coating
which completely covers (inside and outside) the steel surface and
seals the steel from the corrosive action of the zinc protects the
steel even where damage or minor discontinuity occur in the coating.
Financial Considerations: The
initial price of a tapered galvanized steel pole is comparable to
wood. Additionally, a galvanized steel pole¡¯s life expectancy is
significantly longer and has a much lower life-cycle cost.
Environment:
Tapered Galvanized Steel
Poles are the answer to EPA regulations and deforestation issues.
Not only is the zinc coating environmentally friendly, it is
virtually 100 percent recyclable. In addition, tapered galvanized
steel poles can be salvaged and recycled after they have outlived
their design life.
Flexibility:
Tapered Galvanized Steel Poles can be customized for embedded or
anchor base installations, which will expand application
possibilities. Tapered Galvanized Steel Poles can be fabricated to
support larger and heavier loadings with longer spans, and are
capable of handling greater height requirements.
Safety: The
Tapered Steel structures do not require a full-length copper
grounding wire. They are already self-conducting for grounding
purposes. As a result, no installation of a ground wire is required.
Weight:
Weighing approximate 60 percent less than wood structures, Tapered
galvanized steel poles are easier and less expensive to handle and
install.
Maintenance:
After installing tapered galvanized Steel poles, hardware will never
to be retightened due to pole shrinkage. Steel retains its shape and
strength and is not susceptible to damage by woodpeckers, insects,
rot, or fire.
