Meaning:
Models such as BNG and NGD are available, coming in various sizes like DN15, DN20, DN25, DN32, DN40, DN50, etc. Standard lengths include 500mm, 700mm, and 1000mm, with custom lengths available to meet specific site requirements.
For instance, the model BNG (NGD)-B-G3/4×1000 features BNG or NGD to denote the type of explosion-proof flexible conduit. The ‘B’ signifies one end with internal threads and the other with external threads, ‘G3/4’ indicates the pipe thread size of 3/4, and ‘1000’ specifies the conduit length as 1000 millimeters.
