  • Cable for inspecting heat tubes and method of analyzing insertion force of cable
    Patent number: 8775100
    Abstract: A heat tube inspection cable and a method of analyzing an insertion force of the cable are disclosed. The heat tube inspection cable includes a sensor unit configured to detect a defect in a heat tube, a plurality of segment units each configured to comprise a body part and a wheel part rotatably connected to the body part, a signal cable configured to helically pass through the body part of each of the plurality of segment units to transmit electric signal from the sensor unit, and a wire configured to pass through the body part of each of the plurality of segment units to keep the linear configuration of the plurality of segment units like a bead necklace and to provide axial and bending strength.
