Features and Application of Concrete Poles
There are many advantages of pre-stressed concrete poles, so they are developing rapidly. Compared with common concrete poles, their strong points are as follows:
A. saving a great deal of steel, about *0~*0% (employing cold drawn steel wire can save *0%~*0%; employing high s
B. crack resistance increased 3~5 times;tress steel wire can save *0%~*9%); 
C. rigidity increased 1~3 times;
D. reducing the cost (using cold drawn steel wire can reduce *5%~*0%; using high stress steel wire can reduce *2%~*1%); 
E. good durability, can delay the existence and expansion of cracks;
F. protects the environment on which human beings depend on for existence, and reduce the deforestation.
A Summry of Pre-stressed Poles Development Trend
Pre-pressed concrete poles are produced strictly according to two standards namely GB*****4 Circular Reinforced Concrete Pole and GB******4 Circular Pre-stressed Concrete Pole of P.R.C., which guided enterprises and construction units for manufacture.
