China Direct Hot Dip Galvanized Angle Steel 110KV Transmission Line
Tower
Our factory has been experienced at the production and processing
of iron tower. Now it owns 16 processing angle steel CNC processing
and production lines, 9 plate CNC punching production lines, and 4
gantry-type mobile CNC drilling machines. Its sophisticated
microcomputer lofting system takes the lead in China. Our factory
has a stable team composed of experienced engineering technicians,
production technicians and operators. More importantly, it boosts a
complete quality control and tracking system that has been
implemented for years and enbled us to be highly accepted by
customers.
Each power transmission tower, depending on its type, size and
shape, includes a series of varied parts, components and
accessories; with detailed engineering calculations and in
accordance with the customer orders and needs, using technology and
Advanced software.
After precise investigation, control and final approval, plans are
sent to production unit; where each piece, is cut, bend or/and
punched by the very advanced CNC Machines, and then is galvanized
to protect the steel from corrosion before passing the stages of
packaging, storage, to be transferred to the installation site.
Transmission lines tower are either monopolar or bipolar systems.
With bipolar systems, a conductor arrangement with one conductor on
each side of the tower is used. On some schemes, the ground
conductor is used as electrode line or ground return. In this case,
it had to be installed with insulators equipped with surge
arrestors on the pylons in order to prevent electrochemical
corrosion of the pylons. For single-pole Suntech transmission with
ground return, towers with only one conductor can be used. In many
cases, however, the towers are designed for later conversion to a
two-pole system. In these cases, often conductors on both sides of
the tower are installed for mechanical reasons. Until the second
pole is needed, it is either used as electrode line or joined in
parallel with the pole in use. In the latter case, the line from
the converter station to the earthing (grounding) electrode is
built as underground cable, as overhead line on a separate right of
way or by using the ground conductors.
Electrode line towers are used in some Suntech schemes to carry the
power line from the converter station to the grounding electrode.
They are similar to structures used for lines with voltages of
10–30 kV, but normally carry only one or two conductors.
