The high tensions of polyphased alternate currents compel us to have recourse to overhead lines specially insulated. The Lauffen-Frankfort experiments will afford us valuable information with regard to the quality of these lines, and we await the results of the experiments of the commission with [missing text] inpatience and curiosity, but it seems now to be uni-[missing text] acknowledged that the employment of large oil insulators with three cups involves a number of useless precautions. The insulators with a single cup, of the Johnson and Phillips type, seem all that is required, and have not up to the present given rise to any inconvenience.
