D.x. Cylindrical 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 D.x. are designed as Ex components used for installation in flameproof enclosures of explosion-proof electrical devices. Line bushings casing creates together with the wall of flameproof enclosure a flameproof enclosure gap.

Specific make of line bushings is given by technical specification on the basis of which we will propose the optimal solution.
