Pre-stressed Concrete Spun Pole Production Line

Introduction ThisPre-stressed Concrete Spun Pole Production Line is designed in accordance with annual production capacity of 36,000pcs various medium-sized cone pre-stressed steel concrete poles. As far back as the 1930s, 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 30% 70% (adopting cold drawing can economize 30% 60%; in case of steel wire of high strength, economize 40% 69%); 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 25% 40%; in case of steel wire of high strength, economize12% 21%); 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: GB396-94 Annular Armored Concrete Pole and GB4623-94 Annular Pre-stressed Concrete Pole of the People’s Republic of China.
