33KV Galvanized Electric Power Transmission Line Steel Lattice Tower

 

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 10–700 kV, but normally carry only one or two conductors.

 

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.
