2. Description
Line bushings are used to electrically connect equipment in potentially explosive
atmospheres. The connection is always made between a flameproof enclosure (Ex d) and
an enclosure with a different type of protection in accordance with IEC/EN 60079-0.
Alternatively, two flameproof enclosures are connected. Therefore cables are protected
from direct contact.
This will also apply for line bushings with rotatable adapter (twin-path version).
Line bushings with impact protection (UV-protection) can also be used to make an
electrical connection from the outside into a flameproof enclosure.
Line bushings without cables, so called blind plugs, can be used for internal sealing of
flameproof enclosures.
Depending on the design, line bushings are suitable for intrinsically safe, measurement,
control or power circuits, or a combination of these.
All line bushings are sealed with a high temperature resistant, non-tracking resin and
therefore are insulated from the enclosure.
Line bushings can be used in hazardous areas of zone 1/21 and 2/22, as well as for
mining areas in accordance with the certified max. surface / ambient temperature. They
comply with the Directive 2014/34/EU (Richtlinie 2014/34/EU, Directive 2014/34/EU).
