The C-type explosion-proof skylight features a unique structural design. In the event of an explosion or a sudden increase in pressure, it can rapidly release the internal pressure through a specific pressure relief mechanism, while also meeting the lighting requirements.

It can effectively resist the erosion of harsh environments such as humidity and corrosive gases inside the tunnel, greatly extending its service life and reducing maintenance costs.

It has the functions of fire prevention, explosion prevention, bulletproof, anti-theft, and sound insulation, and can be equipped with electrically controlled escape locks and door closers. Effectively block external damage and protect the safety of internal personnel and equipment.
