APPARATUS FOR MEASURING POWER CABLES SIDEWALL PRESSURE UNDER THE CONDUIT

摘要

PURPOSE: A device for measuring the lateral pressure of a cable installed in a duct is provided to confirm the existence of defects of the cable in advance when installing the cable by accurately measuring the lateral pressure generated by installing the cable with tensile force at a desired speed, thereby verifying the stability of a cable state. CONSTITUTION: A device(100) for measuring the lateral pressure of a cable(20) installed in a duct(10) comprises an upper frame, a cable support(120), a rail guide, and a load cell(150). The cable is placed on the upper frame. The cable support has predetermined curvature and supports a lateral surface of the cable. The rail guide is joined to the lower part of the upper frame and facilitates the movement of the upper frame according to tensile force added on the cable. The load cell measures a side load of the cable supported by the cable support according to the movement of the upper frame.
