M.x. Threaded line bushings
Line bushings are used for connecting of electrical respectively optical circuits of two separate parts of ex equipment, usually between instrument part of flameproof enclosure and explosion-protected terminals part, eventually between two flameproof enclosures. Explosion-proof line bushings type M.x. are designed as Ex component (or stand-alone Ex device), intended for installation in flameproof enclosures of explosion-proof electrical devices. Line bushings casing creates together with the wall of flameproof enclosure a flameproof enclosure threaded joint
Specific make of line bushings is given by technical specification on the basis of which we will propose the optimal solution.
