Introduction 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. Technology Characteristics 1. The proportioning and the measurement of concrete should be accurate; 2. The error resulting from alignment and cutting length of reinforcing steel bar should reach 1.5/****0; 3. Tension strength of the reinforcing steel bar should reach *5% of its tensile strength; 4. Demoulding strength of pole should reach *0% of design strength for concrete.
