碍子類의 鹽害對策에 關한 硏究 = A Study on preventing insutators from salt accident

다국어 초록 (Multilingual Abstract)

As there is need of the transmission of the long-distance high electric power with indnstrial development, the method of either the addition of the insulator number or the increase of the insulating distance on the surface of insulator about the stepping of the transmission voltage is usually adopted.
But it has not been the fundamental preventive of accidents, and thogh the Plastering method with the sort of sillicon is widely used, it cant avoid its deterioration and at the same time. There are a lot of difficult things that a large amount of expenses and efforts is necessary to preserve and manage it I have already made public what I have studied in the light of the importance of the mesures of the salt accident, but by studyng and investigating further. I have applied myself to the development of the rational insulator to prevent the salt accident the langstab insulator (or long size insulator) which has merits has generally been used instead of the Suspension insulators, but findind that it has defects that there comes the partial Arc during the dry season after rain, people have newly thought of the screw-shape long size insulator in order to improve these defects and comes to the conclusion that this had better be made practical. I shall state my investigation and research into several problems as to the spiral long size insulator.
