    • Sheaths accommodate a high-voltage conductor in their insides, and annular grooves are respectively provided in flanges of the sheaths outwardly of inserting holes for bolts which are disposed in annular form. Annular grooves are provided in an insulating spacer inwardly of the inserting holes for the bolts. O-rings are respectively provided in the annular grooves. An annular groove is also formed in a flange connection face so as to have bolt inserting holes at its bottom. After the flanges have been fixed by using the bolts, nuts and sealing washers, a liquid packing is injected into the flange connection face groove through a liquid packing injection opening which communicates with the groove. Since a sealing element is disposed outwardly of the bolt holes, it is possible to prevent penetration of rainwater or the like into the gaps between connected flanges with airtightness being retained. It is also possible to readily inject the liquid packing into the gaps between the flanges. By using sealing washers, it is possible to more readily inject the liquid packing into the gaps between the flanges.
    • 护套在其内部容纳高压导体,并且环形槽分别设置在护套的凸缘中,用于以环形形式设置的用于插入孔的孔。 在用于螺栓的插入孔内部的绝缘垫片中设置环形槽。 O形环分别设置在环形槽中。 环形槽也形成在凸缘连接面中,以便在其底部具有螺栓插入孔。 在使用螺栓,螺母和密封垫圈固定法兰后,液体填料通过与槽连通的液体填料注入口注入法兰连接面槽。 由于密封元件设置在螺栓孔的外侧,因此可以防止雨水等渗透到连接法兰之间的间隙中,同时保持气密性。 还可以容易地将液体填料注入到凸缘之间的间隙中。 通过使用密封垫圈,可以更容易地将液体填料注入到凸缘之间的间隙中。
