light pole production line machine equipment

Product Description

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.
