    Prestressed reinforcement concrete pole machine,Electric cement pole making machine,Concrete cement pole plant

         The Prestressed Concrete  Pole machine system is used for concrete electrical pole manufacutring. Its mainly manufacture technology is longitudinal tension by steel wires. Then it can squeeze out the excess water in the concrete under the centrifugal force. Thus, it can greatly improve the concrete density and strength.
        In order to form the concrete more quickly to meet the design strength of more than 70%, steam curing can be carried out so as to shorten the mould-releasing cycle.
         Our factory produces two categories of Pre-stressed concrete electric pole moulds, DMZ&DMD. The Prestressed Electrical Poles manufactured by this series equipments comply with national standard of JC/T364-2001.

    Working Principle of   electric prestressed concrete pole making machine

    1. Adding the slurry into the mould, it is driven quickly and rotated in the same speed of the machine. Each component is separated and released under the centrifugal force. Usually the higher the slurry rotate speed, the better the slurry separating effect.

    2. Centrifugal sedimentation is the use of different density of each component in the slurry, which is rotated under the centrifugal force. To realize the liquid - solid (or liquid - liquid) separation.

    3. The speed of separation is slow when the viscosity of slurry is high.

    4. It is good for centrifugal sedimentation when the slurry density is different in each component.

    Features of electric prestressed concrete pole making machine

    1. Saving a great deal of steel, about 30~70% (employing cold drawn steel wire can save 30%~60%; employing high stress steel wire can save 40%~69%).

    2. Crack resistance can increase about 3~5 times.

    3. Rigidity increases 1~3 times.

    4. Reducing the cost (using cold drawn steel wire can reduce 25%~40%; using high stress steel wire can reduce 12%~21%).

    5. Good durability, can delay the existence and expansion of cracks.

    6, Protect the environment on which human beings depend on for existence, and reduce the deforestation
