OUTER CASE STRUCTURE FOR OPTICAL FIBER COMPOSITE POWER CABLE JOINT BOX

摘要

PURPOSE: A structure of a protection case for an optical fiber composite power cable connection box is provided to stably fix an optical cable within a power cable connection box, thereby minimizing interference between a power cable and the optical cable. CONSTITUTION: An external copper pipe(21) is comprised of cylindrical copper materials. A first flange and second flanges(22,23) are arranged in both lateral surfaces of the external copper pipe. An optical cable insertion pipe(24) is adhered in the inside of the external copper pipe along a longitudinal direction and inserts an optical cable. The optical cable insertion pipe is inserted in a predetermined position of a flange through optical cable insertion holes(22a,23a).
