Streetlight installation is a crucial component of urban infrastructure development, and its safety is directly linked to the safety and operational efficiency of public spaces. To ensure standardized installation and reliable operation, it's crucial to strictly adhere to relevant safety and technical requirements and pay attention to the following key considerations.

1. Preliminary planning and site investigation

1. The installation location should avoid areas with dense underground pipelines, such as water supply, drainage, power, and telecommunications facilities. It should maintain an appropriate distance from trees and buildings to avoid obstruction or collision.

2. Determine the installation height, spacing, and light source type of streetlights based on road width, traffic volume, and lighting requirements to ensure uniform illumination and avoid glare

3. Survey the foundation conditions, including soil bearing capacity and groundwater level. Conduct geological testing if necessary to ensure foundation stability.

2. Selection of Materials and Equipment

1. Materials such as lamps, poles, and cables must comply with current EU standards and possess certificates of conformity and durability test reports. The pole surface must be treated with an anti-corrosion  treatment, such as hot-dip galvanizing. Lamps should be made of die-cast aluminum with excellent heat dissipation.

2. High-brightness LEDs, such as Philips, should be used as light sources; however, their heat dissipation performance and photoelectric parameters must be carefully considered.

3. Cables should be flame-retardant and weather-resistant. Cross-sectional dimensions should be calculated based on the load current and voltage drop to avoid overheating.

4. There's no need to pursue excessively high wattage. Solar products primarily focus on the parameters of the battery and solar panel. Select the appropriate battery capacity based on the desired lighting duration.

3. Foundation Construction and Installation

1. The excavation depth and diameter of the foundation pit must comply with the design drawings. The concrete strength grade must be no less than C25. After pouring, the concrete must be cured to the specified strength before installing the light pole.

2. The position, exposed length, and verticality of the embedded anchor bolts must be precisely calibrated, with tolerances kept within the permitted range.

3. When hoisting the light pole, professional equipment must be used, with dedicated personnel assigned to ensure proper alignment. High-voltage power lines and other obstructions must be avoided. Verticality must be verified after installation, with a deviation of no more than 0.03%.

4. The light pole can be installed at a 45° angle. This angle maximizes solar panel absorption and improves photovoltaic conversion efficiency.

4. Electrical System Safety

1. Cables must be laid in conduits with a minimum burial depth of 0.7 meters. Steel casing must be installed at road crossings. All joints must be waterproof and insulated, and inspection wells must be provided for easy maintenance.

2. Each set of streetlights must be equipped with a separate fuse or circuit breaker, with a grounding resistance no greater than 4 ohms. Lightning protection devices must comply with regulations.

3. The control system should combine timer and light control to avoid wiring complexity. After installation, insulation resistance testing and power-on testing must be performed to ensure there are no short circuits or leakage.

5. Operation and Maintenance

1. Regularly inspect lamp poles for tilt and rust, and promptly tighten bolts and repaint.

2. Clean lamp lenses and solar panels to prevent dust accumulation that could affect lighting performance. When replacing light sources, disconnect the power supply and have the operation performed by a qualified professional.

3. Establish an inspection record system to promptly address issues such as cable aging and grounding faults to prevent prolonged operation with defects.

7. Personnel Safety Requirements

1. Construction personnel must undergo professional training and wear safety helmets and safety belts when working at heights. Warning areas must be established.

2. Outdoor electrical work should be suspended during rainy or windy weather to prevent the risk of electric shock and falls.

3. Before operating tools and equipment, inspect their integrity. Do not use damaged insulation tools or cables.

In summary, streetlight installation is a multi-faceted, systematic project that requires excellent quality and safety control from design, selection, construction, to maintenance. Only by strictly adhering to regulations and paying attention to detail can we ensure the long-term stable operation of the facilities and provide a safe and reliable lighting environment for the public.
