Features

  • Space-saving construction as many single cores are gathered in one single sleeve thus requiring only one cable entry hole
  • Motor mains and thermoprotection cables can be exited in one common sleeve
  • Numbered cores simplify connections and eliminate the usual

Description

A line bushing is a component for the electrical connection between a flameproof ?d? enclosure and an increased safety ?e? terminal box. The bushing consists of a threaded or non-threaded metal sleeve encapsulating one or more cores providing a flameproof barrier. The lengths of these leads vary according to their applications. The depth of engagement of the threaded sleeves and the joint length of the cylindrical sleeve in the wall of the ?d? enclosure must correspond to the EN 60079-0 and EN 60079-1 standards.

After installation the bushing must be protected against rotation and accidental loosening. Recommendations are given under ?Accessories?. Our standard bushings come with threaded sleeves from M10 to M42 or with cylindrical sleeves. They are equipped with cores with a 0.2 to 120 mm? csa. and approved for nominal voltages between 250 V and 3 000 V. See also table ?Electrical data?.

For the connection of intrinsically safe circuits in the ?d? area with the terminal strip in the connection compartment we provide line bushings with blue cores for ?i? low power circuits.

Another product of our line-bushing range is the bushing with terminals. Combining Ex d line bushing with an Ex e terminal we designed an element which is hardly any bigger than a normal line bushing. This bushing plus terminals reduces the size of the terminal box and, at the same time, the installation costs. The bushings plus terminals are rated for 690 V and 1 000 V and certified. We supply them with 2 to 6 poles and threaded sleeves from M24 to M42.

All line bushings have been PTB and BVS tested and certified for their use in hazardous areas according to the European standards EN 50014, EN 50018, EN 50019. BARTEC also has numerous other international approvals for these line bushings.

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 60079-7 concerning electrical operating equipment for explosionendangered areas for above-ground (II) and underground (I) according to ATEX. BARTEC has furthermore obtained several foreign admissions for these line bushings. 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 are used for operating equipment with an internal ignition source for the explosion subgroup IIC and operating equipment with an enclosure volume greater than 2 dm? in zone 1. BARTEC offers a wide range of products with EC type test certification.
