Is the explosion-proof line box with a three-way branch DN25 an explosion-proof conduit box or an explosion-proof junction box?
The above title Q&A - It's actually about explosion-proof conduit boxes with a flat three-way connection.
A crucial component of explosion-proof conduit boxes is the sealing ring, typically made of rubber or silicone, which boasts excellent sealing properties. It effectively prevents dust, moisture, and corrosive substances from entering the conduit box, ensuring the normal operation of electrical equipment. Additionally, the sealing ring serves as a safety feature against electrical fires caused by circuit short-circuits or overloads.

When selecting explosion-proof conduit boxes, it's crucial to first understand the explosion-proof grade and area classification of the work environment. Depending on the different explosion-proof grades and area classifications, different-grade explosion-proof conduit boxes are required. Additionally, attention should be given to material selection. Generally, stainless steel conduit boxes offer superior corrosion resistance and are suitable for use in harsh working conditions. Aluminum alloy junction boxes, on the other hand, have good electrical conductivity and moderate corrosion resistance, making them a common choice.
