Line bushings

Ex i line bushing


We are manufacturing our line bushing
in our own facility;
no relocation, no elongated workbench;
flexible, customer oriented, fast and well-priced

Line bushings are used to electrically connect equipment in potentially explosive atmospheres. The connection is always established either between a flameproof enclosure and an enclosure of another type of protection in accordance with DIN EN 60079-0. Alternatively, two flameproof enclosures are connected. Thus cables are protected from direct contact. Varying with the design, line bushings can be used in intrinsically safe, measuring, control or energy circuits. Line busings that do not feature cables, i. e. they are only cast, can be used to seal flameproof enclosures of the “d“ type of protection. Via line bushings, holes or threads can be closed. If the system is to be extended at a later time, if required, line bushings containing cables can replace the existing, sealed ones.


Our line bushings got the IECEx, EAC, CSA, CSA-US,FM(in accordance to UL-standards) etc. approvals and can be used international wide.
For the european community (ATEX) we have a 'X'-approval, so that you can use this line bushing in excisting products without a re-approval of your product.
