ELECTRIC CABLE SUPPORT IN A PASSAGE OF AN ELECTRIC POWER LINE UNDER GROUND FOR DISTRIBUTION OF ELECTRICITY

摘要

PURPOSE: A cable support for an underground duct is provided to prevent the cable support from being damaged due to an external impact by arranging a roller on the bottom of the cable support. CONSTITUTION: An electric power conduit wall(100) has a joint. A cable support(200) is combined with the electric power conduit wall. A plurality of cables(1000) are loaded on the cable support. The cable support includes a bottom roller and a wheel(265). A bottom roller buffers the impact applied to the cable support when the cable moves. The wheel moves the cable support to an installation position. The cable support is combined with the electric power conduit wall using a fixing bolt(300).
