Construction Site Quality Steel Galvansied Power Electric Transmission Towers
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.
A type of a power transmission tower depends on various factors such as voltage (33kv to 800kv), configuration (vertical or horizontal), line deviation angle (Suspension, Tension & Terminal, Tee off tower).
The design of Power Transmission line tower depends on, type of conductor and Earth-wire, wind zone, deviation angle and material specification. These towers are galvanized to protect the steel from corrosion. The galvanizing coating thickness depends on the weather conditions at the location of tower.
