Street lighting cage refers to the cage-shaped metal structure under the street lighting pole, which is used to protect street lighting equipment and cables. The main function of the ground cage is to prevent the damage or theft of street lighting equipment, and it can provide certain waterproof and anti-corrosion functions. So, are street lamp cages universal?
Usually, the ground cage of street lights is not universal, but is designed and manufactured according to the specific street lighting equipment and installation environment. This is because different street lighting equipment has different sizes, shapes and installation requirements, requiring the installation of specific ground cages. In addition, street lighting equipment and installation standards may also differ between regions, so the design and manufacturing of ground cages also vary.
However, some common specifications and sizes of street lighting cages may have some universality. For example, some standardized street lighting fixtures and installation standards may use similar sizes and shapes of ground cages, allowing for a certain degree of similarity. In this way, the public lighting cages of the same zone or the same project pcan be used interchangeably, reducing design and manufacturing costs.
In addition, some floor cage manufacturers can also provide certain customized services to design and manufacture specific floor cages according to customer needs. In this way, although the floor lamp floor cage is not universal, it can be customized according to specific needs to meet different installation requirements.
Generally, the ground cage of street lights is not universal, but is designed and manufactured according to the specific street lighting equipment and installation environment. However, some common specifications and sizes may have some versatility, and some floor cage manufacturers also offer customization to meet different needs. Therefore, when selecting and installing lamp cagesdaire, you must choose according to the specific situation, consult and communicate with the relevant professionals.
