The utility model discloses a fixed lead wire device of high voltage electrical test concertina type for high tension lead among the fixed dissipation factor test, including the buckle that is used for fixed high tension lead, insulating bracing piece and base, the buckle setting is on the bracing piece, and the bracing piece setting is on the base. The utility model has the advantages of: its fixed lead wire of being convenient for is guaranteed to draw strong wind or mistake factor such as bump and is leaded to the lead wire to drop, improves the device reliability, non -conductive support rod can be based on the not nimble height -adjusting of co -altitude, pressurization lead wire and examination article angle, lifting test data accuracy when guaranteeing dissipation factor test, adoptthe flexible base of interior concealed supporting leg, increase the device's stability, ensure the on -the -spot person and equipment safety. The problem of add the line ball during dissipation factor test and examination article contained angle is too little and the lead wire is unable effectively fix is solved, greatly reduced tests the repetitive rate, reduces testing personnel's safe risk, improves work efficiency. The material of its use is light and handy, carries and puts the convenience.
