Cable feedthrough, pluggable Series 8177

Cable feedthroughs are Ex components that connect electrical equipment within flameproof enclosures to external electrical circuits.Cable feedthroughs – installed in a flameproof enclosure – ensure the flameproof and explosion proof protection of the enclosures.The connection is made between two flameproof enclosures or a flameproof enclosure and an enclosure with a different type of protection, e.g. increased safety.They are approved for use in Zone 1 and 2 hazardous areas.The pluggable version consists of a sleeve in which a single core or multicore or data cable is crimped and protected against ignition. The cable feedthrough is fitted in the Ex d enclosure using a threaded piece in which the sleeve is held by a locking ring. Alternatively, a spare insert can be attached in the threaded piece to fix the conductor at a later point.The pluggable version is mainly used when long conductors and large conductor cross-sections are required. As the sleeve is only inserted and secured in the threaded piece, it facilitates simple installation.
