Electric Power Steel Lattice Hot Dip Galvanized 33KV Transmission
Line Tower
Welcome to visit our website. Ningbo Suntech Power Machinery
Co.,Ltd. is one of the largest professional manufacturers of
transmission line tower in East of China. The company provides
various galvanized steel structures, Stringing tools and equipments
specialized in 500kV and below the line of power tower, substation
structure, communication tower, electrified railway
structure,stringing blocks,come clong clamp,gin pole,cable
rolles,hydraulic puller tensioner,etc.
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.
