Description
Line bushings are essential components connecting flameproof “d” enclosures to increased safety “e” terminal boxes. They consist of metal sleeves encapsulating multiple cores, creating a flameproof barrier. These bushings are available with threaded or non-threaded sleeves and varying lead lengths to suit different applications.
To ensure compliance with EN 60079-0 and EN 60079-1 standards, proper installation is crucial. Threaded sleeves must have adequate depth, and cylindrical sleeves should maintain correct joint length within the “d” enclosure wall. Prevent rotation and loosening with recommended accessories.
Our standard bushings offer threaded sleeves (M10 to M48) or cylindrical options, accommodating cores from 0.2 to 95 mm² and voltages between 250V and 3000V (see Electrical Data table). For connecting intrinsically safe “i” circuits within the “d” area to the terminal strip, we provide line bushings with blue cores.
