铠装电缆格兰头










一、 结构和性能(Structure and function)
　　该系列铠装电缆格兰头结构形式分Ⅰ、Ⅱ型两种。Ⅰ型为一端外螺纹、另一端夹紧装置，Ⅱ型为一端外螺纹，另一端内螺纹。接头体内还通过夹紧置防止电缆拔脱，内装两道弹性密封垫使电缆引出同时阻隔爆炸气体的进、出。主要用于橡胶电缆和塑料电缆进、出防爆技术要求高的引入装置中。其防爆标志为ExdⅡC合格证号：GYB98365.
　　There exist two structures(Ⅰ、Ⅱ)among the series of isolated explosion & seal joint with armoured cable. I tape: one end is external screw, the other clamp. Ⅱ tape one end is external screw. The other internal screw. The joint body has clamp which can prevents cables from being pulled out. Two elastic & sealing filler strips are fixed inside that can make cables spread out and separate exploding gases from going in & out .. the structures are mainly applied in the rubber & plastecs cable devices where explosion-proof technology ids of high requirements which are marked with ExdⅡC, certificate No. is GYB98365.
