Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a ground protective countermeasuring direct current blocking device for an electric overhead line that is able to secure the extent of stable reliability extending over a long period of time as obviating any possible electrolytic corrosion in a beam. SOLUTION: An FW2 is attached to plural beams 1 in an FW interval via insulators. A PW3 connected to a substation is attached to beams 1 and 8 via insulators. Each DCBD 5 is installed in space between each steel pole 1a of these beams 1 and the FW2. At an intermediate part of the FW interval, the FW2 is grounded while a GP6 is installed in space between the FW2 and the PW3. In addition, two CR surge absorbers 7 and 7 are installed at both terminal parts of the FW interval.
