Pre-stressed or Spun Concrete Power Poles are widely used in the developed world to meet the expanding needs of a supporting structure for street, highway and area lighting, athletic lighting, signs, overhead power distribution and power transmission as well as power substations and traffic signals.
The need for concrete poles for use as utility structures is also growing in developing countries due to their economic and environmental advantage over the traditional wood poles.
This Concrete power pole-manufacturing factory specializes in manufacturing concrete poles suitable for electricity transmission and distribution in the East Africa region predominantly in Kenya, Uganda, Tanzania and South Sudan.
The concrete power poles shall be suitable for continuous outdoor use in the tropical areas at altitudes of up to 2,200meter above sea level, humidity of up to 90%, average ambient temperature of +30 degree centigrade.
The concrete power poles are capable of withstanding all specified loading cases including wind on pole and secondary stresses from foundation deflection and rotation. They withstand the loads without failure and without exceeding any specified deflection limitations.
The concrete poles design includes allowances for loads from handling, transportation, and erection without failure, permanent deformation, or damage to the pole. The concrete poles are designed so that the cracking strength of the pole exceeds the required strength calculated from the service loads applied to the pole.
The design of each concrete pole is performed using the applicable codes and standards. Concrete poles design and design calculations are the responsibility of the manufacturer.

Care must be taken when handling, transporting and storing concrete poles to avoid overstressing them or causing surface damage. Lack of care can be costly. Damage can be caused by dropping poles, knocking them together or subjecting them to point loads.
When unloading poles by crane on site, a single point lift may be used. The concrete power pole manufacturing company must establish the correct position of the lift points for the particular poles. To avoid point loads or abrasion damage at the lift point, a protective timber “corset” about 0.5m long should be used. If no suitable timber is available, use a thick wrapping or canvas or jute bagging under the lifting chain.
When the pole is to be lifted for insertion into the ground, a one-point lift must be used. The lift point must be 1/3 of the pole length from the top of the pole. Guard against localized damage at the lift point by taking the precautions given above. For two-point lift, the lifting positions should be 1/4 of the pole length from each of the pole.

Special care shall be given to the proper alignment and the verticality of the suspension poles. Stud poles and stays of angle poles shall be correctly placed in respect to the bisection of the line angle in order to minimize the force on the pole.
The deepness where the pole is going to be placed depends on the poles dimensions. The proceeding of the work on pole mounting starts with their distribution during the track of the overhead line. They are placed next to the hollows where the basis shall be put.
Before the pole is placed into the appropriate location, some ropes are tied preliminary in the 2/3 of its height from the middle of the pole. Then, it is dragged towards the hole where it gets blocked. After that, the raising starts until it is fully placed into the hole. It is held vertically and the filling and cram with soil and stones is carried out. It is forbidden to move with mechanism when it is raised and blocked.
The placement of cross – arms and bare conductors can be done only with a defined way. It should not be higher than the allowed load of the pole. The mounting of the poles and cross-arms is defined by the mounting rules of the manufacturer of the poles for overhead electrical lines.
