1. an insulation balance pipe that is used for superhigh pressure or extra-high voltage transformer has balance pipe (61);

  • It is characterized in that;

    also have pure insulating paper cover housing (62), pure insulating paper inner ring stay (71), pure insulating paper inner barrel (72), pure insulating paper outer ring stay (73) and pure insulating paper outer cylinder body (74);

    Pure insulating paper cover housing (62) closely covers on the outer wall of balance pipe (61), and pure insulating paper inner barrel (72) is enclosed within outside the pure insulating paper cover housing (62), pure insulating paper outer cylinder body (74) is enclosed within again outside the pure insulating paper inner barrel (72);

    Each pure insulating paper inner ring stay (71) is arranged between pure insulating paper cover housing (62) and the pure insulating paper inner barrel (72), the inward end surface of each pure insulating paper inner ring stay (71) is bonded and fixed at pure insulating paper cover housing (62), and the end face outwardly of each pure insulating paper inner ring stay (71) is bonded and fixed at pure insulating paper inner barrel (72);

    Each pure insulating paper outer ring stay (73) is arranged between pure insulating paper inner barrel (72) and the pure insulating paper outer cylinder body (74), the inward end surface of each pure insulating paper outer ring stay (73) is bonded and fixed at pure insulating paper inner barrel (72), and the end face outwardly of each pure insulating paper outer ring stay (73) is bonded and fixed at pure insulating paper outer cylinder body (74);

    Balance pipe (61) has the bend pipe between two sections straight tubes and the two sections straight tubes.
