Regarding the installation direction of the explosion-proof isolation seal box for cable protection tubes
Thread Content
I would like to ask the experts: are there any requirements regarding the installation direction of cable protection tube explosion-proof isolation sealing boxes? Should they be installed in a straight “Y” shape or in an inverted “ʎ” shape?
“The Y-shaped sealing box should be installed at an angle in the direction of the instrument.
There’s not much information available on on-site installation, and I just can’t figure out how to get the sealing filler inside in a ‘Y’ shape
I have been looking for the relevant specifications to guide the installation method, but unfortunately I couldn’t find any. However, based on on-site experience and the requirements of the supervisor, the filling port should face the instrument side； But there is another theory stating that the filling port should be oriented downward to allow water to flow out; however, this theory has not been verified by anyone. Therefore, in practice, the filling port is generally installed with its opening facing the instrument side. I hope this helps, and I also hope that experts can provide an explanation – ideally with some standards to support it. Thank you!
