This Pre-stressed Concrete Spun Pole Production
Line is designed in accordance with annual
production capacity of *6,**0pcs various
medium-sized cone pre-stressed steel concrete
poles.
As far back as the ***0s, the Peoples Republic of
China used armored concrete pole. With the rapid
development of power industry, the production and
use of concrete pole has developed tremendously
thereupon.
Pre-stressed concrete pole develops rapidly because
of much superiority. Compared with common concrete
pole, its advantage is as follows:
Economizing steel in a large amount, about *0%~*0%
(adopting cold drawing can economize *0%~*0%; in
case of steel wire of high strength, economize
*0%~*9%);
Crack resistance is improved by 3~5 times;
Steel performance can be improved by 1~3 times;
Reduction of cost (adopting cold drawn wire can
economize *5%~*0%; in case of steel wire of high
strength, economize*2%~*1%);
Good endurance can delay the appearance and
expansion of cracks;
Protecting the environment that mankind depends on
for existence, and reducing deforestation.
Pre-stressed concrete poles are strictly in
accordance with two standards: GB*****4 Annular
Armored Concrete Pole and GB******4 Annular
Pre-stressed Concrete Pole of the Peoples Republic
of China.
