Electric wire pipe for prevention of underground distribution line

PURPOSE: A conduit tube for protection of a power distribution type underground wire is provided to prevent an underground wire to be burned through fire by rapidly extinguishing the fire by the medium of a fire hydrant. CONSTITUTION: An external case(10) is composed of an elastic body(12), an opening and closing plate(13), a base plate(14), and a floating body(15). The external case safely protects underground wires(L1, L2) from external force. The underground wires are connected by the medium of an internal case(20). The internal case is composed of a metallic conduit tube(22), a reference bar(23), and a binding metal device. A first moving detection sensor(30) is operated by the reference bar and outputs a first moving detection signal to a controller(70). A water level detection sensor(50) is operated by the floating body and outputs a water level detection signal to the controller.
