Description
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 Ex-zone. 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 DIN EN 60079-0 and DIN EN 60079-1.
