SEALING STRUCTURE WITH NON-SOLDERING IN OIL-FILLED POWER CABLE FOR HIGH VOLTAGE

摘要

PURPOSE: A sealing structure with non-soldering in an oil-filled power cable for high voltage is provided to improve the sealing structure by changing an end portion of a connection case of the oil-filled power cable for high voltage or a protection tube of termination to a non-soldering assembly method. CONSTITUTION: A plurality of circular wrinkles are formed on an inner circumference of silicon packing(20). Each circular wrinkle has a pitch. An outer circumference of the silicon packing(20) has a constant gradient. A plurality of aluminium protection tubes(11,12) are closely contacted with inner faces of both end portions of the silicon packing(20). The first flange(30) and the second flange(40) are coupled with the aluminium protection tubes(11,12). The first flange(30) and the second flange(40) are connected to a plurality of stud bolts(34). One end portion of the stud bolt(34) is fixed on the first flange(30). The other end portion of the stud bolt(34) is combined with the second flange(40) by using a nut(35).
