PURPOSE:To prevent the deterioration of quality of the electric equipment due to absorption of moisture during the transpotation or the like by mounting a hygroscopic agent bag at the side of an oil-filled cable connection box of a wall-passing bushing, enclosing it with a bag of low air permeable material and removing it at the time of mounting connecting wires for a field assembling work. CONSTITUTION:The bag 14 made of cloth or paper for containing the hygroscopic agent is mounted at the terminal 5b of the wall-passing bushing 5, and the bag 15 made of low air permeable material such as PVC or the like to enclose it is airtightly sealed with a rubber string or the like at the body 5a around the oil-filling cable connection box of the bushing 5. Thus the product is delivered, is installed in this state in the assembling work of the bushing at the terminal of the cable on the installing place or the like, when the connecting wires 10 are mounted, the bags 15, 14 are removed, oil is filled therein, and the assembling work of the entire equipment can be completed. Thus, this can prevent the deterioration of quality of the wall-passing bushing due to absorption of moisture during a period to the completion of the assembling work. |
