Conductor Bushings Series 8174

Transcription

1 > Current lead-in for Ex d enclosures > 1 to 72 conductors combined in one current lead-in > Series screw-in plug-in > For voltages up to max. 1 V > For size conductor up to 7 mm E The conductor bushings are used to provide the wire connection between flameproof enclosures and increased safety enclosures. The conductors are potted with high-quality, creepage-resistant PU-resin and are thus insulated from the enclosure wall.

The installation of bushings must meet requirements of IEC/EN A thread engagement of at least full threads is required (with a pitch of 1, mm, 8 mm screw-in depth in the enclosure). The conductor bushings are generally screwed in from the inside of the flameproof enclosure (inverted installation is only possible by using a special lock; upon request). The bushings must be secured against self-loosening by using backing strips or epoxy adhesives (see illustrations 1). Fig. 1 Threaded conductor bushing 8174/1 8867E The plain type bushings can be inserted directly into the corresponding hole drilled in the enclosure. Flameproof sealing is established via a cylindrical gap between enclosure and bushing. Observe the tolerances given in the operating instructions when using this method. The installation is simplified by using a threaded fitting, having the threaded gap on the outside (min. thread turns according toi tolerance from ISO 96-1 and ISO 96-3b) and cylindrical gap on the inside. A flameproof seal is thus ensured (see illustrations 2). The threaded fitting is also secured against self-loosening by using tab strips or adhesive.
