Do substation buildings need windows?

Do the substation buildings of petrochemical enterprises need windows? How are the factories where you work designed?
Windows should still be included; otherwise, there will be poor ventilation and insufficient light. However, they should be avoided in areas prone to explosions, or at least kept at a sufficient distance from such places
There should be. Not only from the perspective of lighting and ventilation, but more importantly, heat dissipation must be taken into account. As for the particularities of the petrochemical industry, especially regarding explosion prevention, comprehensive considerations should be given to aspects such as the location selection of substations and the explosion-proof performance of the equipment used in them.
The transformer room should have as few windows as possible to prevent unauthorized persons from entering through them； Normally, apart from during duty rounds, it’s best to have as few people as possible inside; if entry is necessary occasionally, indoor lighting can be used ； The heat dissipation issue can be addressed by installing louvers of the same width as the door above and below it in the transformer room to facilitate ventilation. If the bottom of the door is at the same level as the floor, the lower part of the door can be made in the form of louvered panels, or a window can be created in the upper part of the wall opposite the door to install louvered panels there. The door is opened enough for sufficient brightness during maintenance.
I agree with the moderator’s opinion; transformers can be designed for outdoor or semi-outdoor, open installation. There is no transformer room door, so there is no need to consider its heat dissipation issues.
I agree with the moderator’s view; our transformer room uses this exact design. Additionally, in the transformer room, the transformer is installed on a platform about 1 meter above the ground. In the space about 1 meter below the transformer, one side (on the side of the transformer’s access door) is covered with mouse-proof mesh, which helps with ventilation.
The remarks from those upstairs were all very insightful. I only paid attention to whether to add windows, ignoring the definition of windows. When we talk about windows in substation construction, we generally refer to louvered windows, not the ordinary glass windows.
Shutters are a pretty interesting idea; they should be made of metal, so they can’t be destroyed, which prevents people from coming in and stealing cables or something like that
From the perspective of operation and maintenance, it’s best not to use windows, as dirt might get in, especially in substations that are unattended. Since lighting isn’t a major concern in such places, the idea of having many windows is an outdated one. In my opinion, it’s better to avoid using windows or to use as few as possible; however, exhaust systems should be in place, preferably fans that operate automatically based on temperature differences (without requiring electric power), which is more than sufficient to meet the requirements!
We use fixed lighting windows that cannot be opened. External mesh~
