3-Legged Steel Communication Pipe Tower

Introduction:
Main components: steel pipe tower, steel pipe or steel etc. the other parts of the lattice tower.
:,,,,.,,,.10,448MPa.578Mpa.,,,,,.75OkV,,,:,,10%-20%..,,,,,,.
Steel pipe tower development trend: China's transmission tower structure with steel, compared with foreign
advanced countries, the variety of single, low intensity, can choose a small room. When the tower load is large,
only the use of composite section to make up for the shortcomings of the low strength material, which increases
the design and processing of workload and investment. The United States "transmission tower design
guidelines" recommended by the Chinese Communist Party for the design of 10 materials standards for
designers to choose, the yield strength of the high strength steel to reach 448MPa. Russia's "steel structure
design code" in the column of the strength of steel has reached 578Mpa. In recent years, with the continuous
development of metallurgical industry in our country, the production of high strength steel is no longer difficult.

The structure of high strength steel quality improved rapidly and steadily, supply channels increasingly patency,
transmission line tower with high strength steel provide the. In the pre research project of 75OkV transmission
line, the Research Institute of electric power construction of the national electric power company has studied the
structure, design parameters, the supporting bolts and economic benefits of high strength steel. It is considered
that the technology and the use of high strength steel has been fully equipped with the conditions in the tower,
and the use of high-strength steel can reduce the weight of the tower. But the biggest obstacle to the use of
high strength steel is the supply of steel material. Steel tower needs a variety of steel varieties, the
specifications of the bulk of the demand is not high, while the high strength steel forming difficult, high cost of
rolling, roll adjustment difficulties, so that the production of high strength steel steel enthusiasm is not high,
difficult to guarantee delivery.

The use of steel tube tower:

In the eighties of the last century, in many countries in the world in the development of UHV transmission line,
began to pipe profile application to the structure of the tower, appeared with the pipe into the advocate of the
tower body of steel tower. In Japan, the 1000kV ultra high voltage line and tower in almost all of the use of the
steel tube tower, they are very thorough research on the design of steel pipe. Drawing lessons from foreign
experience, the domestic 5OOkV Double Circuit Tower and the tower with the tower in the four tower has also
been using steel pipe, reflecting its good performance and efficiency. Which is characterized in that: one tower
pressure component shape coefficient can be reduced, circular tube than angle almost small times); the second
is in the equal section area, round tube radius of gyration angle about 20% larger than that of; the third is the
load carrying capacity of structure is improved, generally speaking, steel pipe tubby angle steel tower amount
decreases by 10% - 20%; at the same time, it also can reduce the number of rod, shortening the cycle of tower
construction, easy structure diversification. But the use of the steel tube also has the steel tube profile
specification variety limited, the outside quality is not good, the price is higher and lower, simultaneously the
steel tube connection node structure is complex, the processing production efficiency is low.
