A.Brief of Concrete Electrical Spun Pole

I.Concrete Electrical Spun Pole Look:

Concrete electrical spun 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.Working Principle:

Concrete electrical spun poles generally are manufactured in centrifugal casting process.Centrifugal casting or spin casting is the best and cost-saving method for concrete electrical 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.

  B.Process of Production

Products Introduction:

1.Spinning machine

The technology that our spinning machine adopted is derived from Germany in 1980s.Through around 30 years experieces accumulation and improvement,our technology on spinning machine has exceeded the original,with advantages of wide range of spinning speed,lower noise,easy maitenance and operation.In addition,we provide to customers with multiple configuration of motors for the purpose of meeting customers different demands on operation,cost,maintenance and automation.

The raw materials of our mould meet international standard:Euro Code,US Code and China GB,so our finished mould has advantages of high strength,precision and non-deformation.

Each of our steel mould is mechanically processed by different machine tools for the purpose of decreasing deformation frequency,higher strength for different loading capacity of pole,and more precise of each part of mould.The mould processed by this technique will have advantages of long life-about 30 years,easy to operate-easier for workers to assemble two halves of moulds,non-deformation of mould,and the finished pole from this kind of mould will have a neat apearance

3.Steam Curing:

The pole after centrifugation needs to be steam cured to strengthen to a given value.The whole process will be in a given temperature,moisture and depth environment.The process of steam curing takes four hours.

1.Molds in working

Note:Before production,brush demounding agent on the inner wall of mold.

2.Spinning Machine

Note:Spinning time is dependent on spinning speed.

3.Boiler in working

Note:Capacity of Boiler have an important relationship with your estimated productivity.

4.Bridge Crane in working

5.Feeding Machine in working

Note:This machine is optional,if you have enough human labor,this machine is not necessary

D.Packaging and Delivery

  

Note:For the purpose of Saving cost for customers,packages are nude.Generally,delivery in containers:top open or regular.

For mold,due to length,seperate into sections or delivery in whole.

For crane,seperate into sections and install at work site.
