摘要： An explosion-proof electrical apparatus comprises two enclosures containing electrical devices. The enclosures are physically interconnected by a one-piece or two-piece hollow sleeve member which is screwed into threaded holes of the enclosures. A fitting assembly mounted in the sleeve member comprises a hollow feedthrough bushing screwed into the sleeve member, a hollow feedthrough seal member screwed into the feedthrough bushing, and a plurality of conductors extending through the feedthrough seal member and electrically connected to the electrical devices. The conductors are embedded in sealing compound which occupies the feedthrough seal member. During assembly of the fitting assembly, the feedthrough seal member is positioned within the sleeve, and the feedthrough bushing is screwed along the feedthrough seal member and is simultaneously screwed into the sleeve.

摘要： A damming device for a conductor in a cable gland connector is described herein. The damming device can include a first portion having a first thickness of a flexible elastomeric material disposed between a first diameter and a second diameter. The damming device can also include a second portion having a second thickness of the flexible elastomeric material disposed between a third diameter and the second diameter. The damming device can also include a hole having the third diameter. The first diameter is greater than the second diameter, and the second diameter is greater than the third diameter. Further, the first thickness is greater than the second thickness. The damming device can be disposed, under tension, within a slot formed between a top portion of a compound chamber and a bottom portion of a union body.
