This kind of line bushing makes installation of line bushing in flame-proof enclosures (Ex d) easier, much faster and very safe.
Varying with the design, line bushings can be used in intrinsically safe, measuring, control or energy circuits By the pluggability you need a locking ring and a screw up protection Standardized the diameter is 10mm up to 40mm variation on this must be approved by a notified body in the case of Ex application.
The use of the 'twin-path' - line bushing is recommended if the location of the strands must be variable to the final assembly, regardless of the final position of the screwed sleeve. Until the final assembly, the cable bushing is rotatable and shall fixed after completion (mandatory).
We recommend to use this line bushing especially for large diameter wires or many strands as a feed through of the ex d enclosure. The possibility of rotating the line bushing to the optimal place for installation of wires at the terminals make the installation safe and easy and takes care for the outer sheath of the cables.
