Brief of Concrete Electric Pole

 

I.Concrete Electric Pole Look:

 

Concrete electric pole can be made in many shapes.Poles up to 40 feet long with square or rectangular solid cross-sections are easy to manufacture,occupy less room during transporation,and faciliate positioning of steel at corners for maximum resisting moment at a given depth.Circular hollow cross-sections are better for longer poles.Because hollow,weigh less.And because they are spun at high speeds in casting operation,then concrete is denser and stronger.

 

II.Design Consideration:

 

A pole generally acts as a cantilevered structure ,and should be designed and analyzed as a tapered member with combined axial and bending loads.Because shear forces are small compared to bending moments,concrete electric poles are very resillient.Axial loads are small,too,and are generally ignored except when the structure is guyed.

 

III.Working Principle:

 

Concrete electric poles generally are manufactured in Centrifugal casting process.Centrifugal casting or spin casting is the best and cost-saving method for concrete electric pole production.In centrifugal casting,a steel form(mold) is placed on machine,partially filled with amount of precalculated concrete ,then spun for several minutes(time for spinning depends on motor speed).The tremendous centrifugal forces created by the spinning consolidated the concrete by forcing it against on the wall of the form.Excess water that is squeezed out of concrete is poured from the hollow cavity created in the center of the pole.After spinning,the form is steam cured until the strength of concrete is 3500psi.The prestressing wire is then released,and the pole is air-cured for 28 days.The result :a hollow pole made of dense concrete.
