In power transmission line project, double circuit transmission line steel tower often used. For a double-circuit transmission line, which has two circuits, both tubular and lattice steel towers can be designed so as to support two circuits of electrical current. Double-circuit transmission towers hold the different conductors stacked atop one another, while in single-circuit towers the conductors are lined up horizontally.
MEGATRO provide many types of 33KV double circuit monopoles for overhead power transmission, this 33KV double circuit monopole are widely used for oversea clients, especially African clients.
33KV double circuit monopoles for overhead power transmission is
used for urban power grid, it is one good choice for city power
transmission due to its less space, less time to install and are
aesthetical in appearance, compared to conventional lattice tower.
Monopole towers use a minimal space requirement, and with a solid
and stable structure from which to add additional carriers. Till
now, we had provided too many 33KV distribution and transmission
pole for African market these years.
MEGATRO is equipped with sophisticated machinery and equipment for
the manufacture of double circuit monopole for 33KV power
transmission line project, we have skilled worker with certificated
welders, and offers a variety of monopole types to meet client
specific. Tapered steel and flanged steel poles feature designs
that blend well into the environment and require minimum space for
installation. Flanged steel poles are easy to handle and install.
Slip type with precision fitted connections allow quick assembly of
sections and total poles seems uniform and harmony with
environment, especially accept by our foreign clients. Pole
sections are available with identical base flange plates, allowing
for simplified modifications of mounting heights.
In material we often adopt mild steel (ASTM A36, Q235B), high
strength and lower alloy (ASTM A572 GR50, GR65, Q345B, Q345C, Q420,
Q460, S355J0, S355JR and equivalent materials). MEGATRO can
optimize design and adjust monopole size to make it less weight,
solid strength and economic cost. For tower surface, we adopt
hot-dipped galvanization, or zinc coating on towers and components
to meet ASTM-A123 standards or client accept standard...
