  (1)接线口为螺纹式。国外防爆电机大多属于这种形式,国内也有不少厂家已开始生产。这种形式,钢管可直接与防爆挠性管进行连接。防爆挠性管上应配套连接件,与钢管是螺纹连接,否则挠性管上应加装防爆活接头。在引入非密封的防爆电气设备前,在防爆挠性管与电气设备接线口处应装设隔离密封装置。电缆引入时加防爆密封接头,电线引入时加防爆隔离密封盒。当电气设备的接线盒自带密封装置时,可不必另加隔离密封装置。防爆电气设备直接与防爆挠性管配套连接,既便于安装,又安全、美观。

  正常情况下,在±0.000m平面,先由室外桥架引入,进入室内后至用电设备附近沿墙或柱引下至电缆沟(敷设完毕后封死,以防白蚁和进水),然后穿管在地面下暗敷设至电动机旁,再用防爆挠性连接管接至电机接线口处。而在其它高于±0.000m上的平面,电气线路基本上都是由桥架架空引入,然后由桥架穿管架空敷设至电动机旁,再由防爆挠性连接管引入电机接线口。
