Because of its resilience, the lighting infrastructure is guaranteed to stay stable and operational even in the face of unfavorable circumstances, which lowers maintenance costs and improves public safety.

Not only are reinforced concrete poles long-lasting, but they are also reasonably priced. When considering long-term infrastructure investments, businesses and municipalities can find them to be a cost-effective option due to their extended lifespan and low maintenance needs. Furthermore, they don’t corrode or attract pests like metal or wooden poles do, which can eventually wear down.

The adaptability of poles made of reinforced concrete is another benefit. Their height, shape, and finish can be altered to meet various functional and aesthetic needs. These poles can be customized to blend in perfectly with the surroundings while offering dependable lighting, whether it’s for streets, parks, or commercial areas.

All things considered, purchasing reinforced concrete poles for outdoor lighting purposes is a wise move. They are a popular option for contemporary infrastructure projects due to their strength, adaptability, and durability, which guarantees well-lit and secure public areas for many years to come.

For outdoor lighting, reinforced concrete poles are a great option because of their strength, resilience to weather, and durability. These poles provide a dependable and long-lasting way to light up public areas like parks and streets. Reinforced concrete poles are less prone to corrosion and damage than their wooden or steel counterparts, guaranteeing consistent performance over many years with little upkeep. Their combination of the added strength of steel reinforcement and the inherent durability of concrete makes them an affordable and sensible choice for a range of outdoor lighting applications.

Advantages of reinforced concrete supports for street lighting

When it comes to installing lamp stands, reinforced concrete stands offer several benefits over wooden and metal alternatives. Among the benefits are the following:

• resistance to corrosion, biological destruction, exposure to aggressive environments;
• increased fire resistance;
• seismic resistance;
• ability to withstand high loads;
• manufacturability – the products are easy to manufacture, have standard sizes and are mass-produced;
• durability – the service life of the product, subject to compliance with the manufacturing technology, transportation and installation rules, is at least 50 years;
• repairability – damage that occurs during operation (cracks, crumbling areas of concrete) are easily repaired with a repair compound;
• low operating costs – reinforced concrete supports must be inspected every few years to identify and eliminate surface defects;
• low cost.

Disadvantages of reinforced concrete supports

There are certain drawbacks to reinforced concrete pillars, which include:

• heavy weight – the product weighs at least 700 kilograms, which complicates loading and unloading operations, transportation and installation of supports;
• complexity of dismantling — requires the use of special equipment;
• expensive disposal of structures that have served their purpose;
• low resistance to impact loads – concrete cracks and crumbles when the stand accidentally hits concrete or metal during transportation, the support can be damaged by vehicles or snow removal equipment;
• unsightly appearance – concrete products are not very aesthetically pleasing, dirt settles on the rough surface over time.

Wooden poles that deteriorate quickly are increasingly being effectively replaced by reinforced concrete stands for outdoor lighting. However, metal supports that are more functional and aesthetically pleasing as well as composite material street lamp stands are gradually replacing products made of reinforced concrete these days.

Types of reinforced concrete lighting supports

The features of lighting supports made of reinforced concrete vary depending on the product version.

Lamp stands vary:

• by manufacturing method (vibrated and centrifuged);
• longitudinal shape (conical, cylindrical, prismatic, pyramidal);
• cross-sectional shape (round, rectangular, faceted);
• presence of an internal cavity (solid and with a cavity);
• different forms of reinforcement (with conventional reinforcement, pre-stressed).

The bearing capacity is determined by the support parameter, such as the computed bending moment, which is primarily dependent on the type and method of reinforcement. Permeability is influenced by the grade of the concrete (normal, reduced, especially low). Products are chosen for use in situations involving higher wind loads, exposure to harsh environments, etc. based on these features.

In situations where overhead power lines are used for lamp power supply, supports featuring a solid shaft may be employed to suspend those lines. Street lighting fixtures can be connected to subterranean or overhead electric cables using racks that have an internal cavity. Racks for overhead feed lack a hatch, while supports for lighting fixtures with cable feed have one for the purpose of installing and maintaining electrical switching equipment.

Dimensions and weight of products

Despite the abolition of these standards, the majority of manufacturers still construct reinforced concrete racks for outdoor lighting within the parameters of GOST 23613-79, GOST 26071-84, and GOST 22687.1-85, which refer to conical centrifuged reinforced concrete racks for high-voltage power transmission line supports and vibrated reinforced concrete racks, respectively.

The USSR-developed standard designs, such as Series 3.407.1-136 "Reinforced concrete supports for 0.38 kV overhead lines" and Series 3.407.1-143 "Reinforced concrete supports for 10 kV overhead lines," are also utilized.

Supports SV

The most widely used kind of supports made of reinforced concrete is the vibrated rack (SV). Hexagonal prismatic products are commonly used as street lamp racks, and they are intended for the installation of overhead power lines up to 35 kV.

Hexagonal lighting supports made of reinforced concrete:

• with air eyeliner-SV-1.2-10;
• with cable eyeliner-SV-0.8-10.

SVN supports

SVN racks also belong to faceted reinforced concrete supports of outdoor lighting – its cross section is a hollow octagonal inside.

• with air eyeliner-SVN 9-1, 1-2;
• with cable eyeliner-SVN 9-1, 1-2U

Supports of the SKC

SKC racks are hollow within, round-sectioned, reinforced concrete lighting supports that are formed by centrifugation of heavy concrete.

SCC provides air eyeliner support.

SKTs are supported by cable connectivity.

Conclusion

The bearing capacity of reinforced concrete posts, which is dependent on the components and manufacturing process of the products, should be considered when choosing posts to mount street lamps on. The permeability of the concrete and indicators of frost resistance must be considered if the supports are meant to be used in challenging circumstances.

Purchasing lighting poles made of reinforced concrete from reliable manufacturers is advised, as product durability can only be ensured by rigorous adherence to production processes and the use of premium raw materials.

Because of their strength, resilience, and endurance in inclement weather, reinforced concrete poles have gained popularity as an option for outdoor lighting. These poles are a dependable choice for a variety of outdoor settings because they are made to resist strong winds, torrential rain, and even the odd unintentional hit.

The minimal maintenance needed for reinforced concrete poles is one of their main benefits. Concrete poles are strong and durable for extended periods of time, in contrast to metal or wooden poles that may rust or decay. Over time, these long lifespans result in cost savings because they require fewer replacements and repairs.

The adaptability of the size and design is an additional advantage. It is possible to customize reinforced concrete poles to meet particular lighting requirements and design tastes. They may be adjusted to improve the general appearance and performance of the lighting system, whether they are utilized in public parks, commercial spaces, or residential neighborhoods.

Additionally, using reinforced concrete poles is recommended by environmental factors. Because it can be obtained locally, concrete is a sustainable material that lessens the environmental effect of transportation. It is also possible to optimize the production process for these poles in order to reduce waste and energy usage.

In summary, reinforced concrete poles offer a robust, low-maintenance, and environmentally friendly solution for outdoor lighting. Their ability to endure challenging conditions while providing consistent performance makes them an excellent choice for illuminating outdoor spaces effectively and efficiently.
