原価が廃棄損分割高となる。The above-mentioned conventional oil-impregnated paper storage can has the following problems. (1) For heating vacuum evacuation and filling of insulating oil, a dedicated large-scale heating vacuum evacuation pot and oil filling case are required, so small volume processing is not only more expensive than large volume processing, but also manufactured only at a factory with permanent equipment. I can not do it, and I can not respond when necessary at the construction site. (2) Since the tin can and the insulating oil inside the tin can are discarded, the cost is high due to disposal loss. (3) When the oil-impregnated paper is taken out from the tin can, the operator may be cut at the edge of the cut open portion of the tin can, which is a problem in work safety. (4) Since the inside of the tin can is not pressurized, the insulating oil and the oil-impregnated paper inside may absorb moisture during long-term storage, which is a quality problem. Moreover, since such long-term storage items are discarded, the cost becomes a high disposal loss division cost.
