Prestressing Concrete Pole Tensioning Machine
Prestressed Concrete Spun Pole generally is produced with centrifugal force with presressing tensioning process of concrete pole tensioning machine. The production process is to tension the prestressing steel wire cage in longitudinal direction inside the concrete pole mould . Then the excess water will be squeezed out from concrete with centrifugal force so that to improve the intensity and strength of concrete . The dismolding and tensioning force releasing will be done after the concrete designed strength will reach to 70%. With exerting prestressing force, the concrete electricity pole will gain higher breaking load.
During prestressed concrete pole and partial prestressing concrete pole production , the tensioning process is very important. The concrete pole prestressing tensioning machine controls the tensioning force precisely thus implement the exerting prestressing force in advance to make sure concrete electric pole will gain designed breaking load.
