Flameproof Ex d cable entries are elements which allow electrical cables to be introduced into an Ex d enclosure, without danger of explosion. The additional Ex e terminal housing is not required. A main distribution box may by used or the connections can be made outside the Exzone.The cable entry consists of a threaded metal sleeve, in which a sheathed cable is anchored and encapsulated. The individual cores are then connected directly inside the flameproof enclosure. The length of cores and cables are customer-tailored. All cables come with standard green-yellow earth leads. The length of engaged thread between the sleeve and the flameproof ?d? enclosure must comply with EN 60079-0: 2006, EN 60079-1 and EN 60079-31.
The cable entry is normally inserted from the inside of the flameproof enclosure. A special version can be supplied for insertion from the outside, provided that removal is possible with a special tool only. After installation, the cable entry must be protected against turning and loosening, corresponding recommendations can be found under accessories.
All line bushings have been certified by the Federal Physical-Technical Institute in accordance with the European standards EN 60079-0, EN 60079-1 and EN 60079-31 concerning electrical operating equipment for hazardous areas for above-ground (II) and underground (I) according to ATEX.
When the 94/9/EC guideline comes into force on 01/07/2003, explosion protected operating equipment must be properly Installed in accordance with EN 60079-14. Among other things, section e) of this standard requires that cast, pressure-proof cable insertions according to EN 60079-1: 2007 are used for operating equipment with an internal ignition source for the explosion sub-group IIC and operating equipment with an enclosure volume greater than 2 dm? in Zone 1. BARTEC offers a wide range of products with EC model test certification.
