PLS / MS Overhead Line Tower Single Circuit Steel Lattice Tower 66kV 330kV
66kV/230/330kV Overhead Line power tower single Circuit Tower steel lattice tower :
Lattice towers are the workhorse of the world’s electric grid.
ASTM A36 Equivalent to Chinese standard Q235B.
Since its establishment 50 years ago, Henan Dingli Pole & Tower Co.,Ltd has been devoting itself to research,
development and manufacturing of pole and tower. It has rich experience in manufacturing and design.
66kV/230/330kV Overhead Line power tower single Circuit Tower steel lattice tower : The tower was erected
on the tower cat shaped head, two wire lightning line, an isosceles triangle arrangement, it is also the 110
thousand kV and above voltage transmission lines of common tower can save line corridor, the economic and
technical indicators than the glass shaped tower is worse.
The product features:
As the traditional transmission line equipment, Angle steel tower has the field widely used, the characteristics of the
design code, the craft is mature, at different distances, different voltage level are showing the advantages and general
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.

Here is fabrication process for our transmission tower; however, both parties must discuss all drawings and
confirm all shop drawings, technical specification, and which standard to conform. Before mass production,
we must received all signed approved shop drawings and technical documents from our client.
Our Fabrication shall be in strict accordance with detail Drawings prepared by the Contractor and approved
by the Engineer. Fabrication shall begin after the approval of the shop assembly and tests.
|Shearing||A:Shearing and cutting shall be performed carefully and all portions of the work which will be exposed to view after completion shall be finished neatly. Manually guided cutting torches shall not be used.
B:All material over 13 (or 12) mm thick shall be cold sawn or machine flame cut.
C:Cropping or shearing shall be allowed for material thickness of 13 mm or less.
Flame cutting of high yield steel shall be preceded by a slight preheat operation by passing the cutting flame over the part to be cut.
All flame-cut edges shall be ground clean.
|Bending||Our company owaned the bending machince. Frether more, we can manufacture the towers with hot bending or cold bending according to client's requirements.|
|Welding||No welding shall be done unless prior approval has been obtained from the Engineer.
Welding shall not be allowed at tower attachment points for conductor, shield wire, insulators or associated assemblies or brackets
|Sub-punching||All holes in structural steel less than 10 mm thickness may be punched to full size unless otherwise noted on the approved Drawings. Holes shown on the Drawings as drilled holes and all holes in structural steel 10 mm or more in thickness and tension members of cross-arms shall be drilled or sub-punched and reamed.
All holes shall be clean cut and without torn or ragged edges. All burrs resulting from reaming or drilling shall be removed. All holes shall be cylindrical and perpendicular to the member.
Where necessary to avoid distortion of the holes, holes close to the points of bends shall be made after bending.
|Punching||For punching to full size, the diameter of the punch shall be 1.0 mm larger than the nominal diameter of the bolt, and the diameter of the die shall not be more than 1.5mm larger than the diameter of the punch. For sub-punching, the diameter of the punch shall be 4 mm smaller than the nominal diameter of the bolt, and the diameter of the die shall be not more than 2 mm larger than the diameter of the punch. Sub-punching for reamed work shall be such that after reaming no punch surface shall appear in the periphery of the hole|
|Hole Size||Where holes are reamed or drilled, the diameter of the finished hole shall be not greater than the nominal diameter of the bolt plus 1.0 mm.|
|Galvanizing||All material shall be hot-dip galvanized after fabrication in accordance with the latest revision of GB/T 13912-2002 or ASTM Specification A 123.
Material that has been rejected because of bare spots or other coating defects shall either be stripped and re-galvanized, or the uncoated areas shall be recoated by an approved method.
All plates and shapes which have been warped by the galvanizing process shall be straightened by being re-rolled or pressed. The material shall not be hammered or otherwise straightened in a manner that will injure the protective coating.
Approval shall be secured from the Engineer if galvanizing is done outside of the Contractor's plant.
All galvanized steel work shall be protected against white storage stain by using an approved solution treatment immediately following galvanizing.
