| Introduction |
| 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 People?s 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 People?s Republic of China |
