Abstract

PURPOSE: To modify the construction of the head section so that steel material can be used to construct parts housed inside the expansion chamber regardless of the current capacity.
CONSTITUTION: An expansion chamber of the oil-contained bushing is built with conductive material according to the current capacity. On the bottom of the expansion chamber, a sliding connection element 22 is provided into a hole through which the central conductor 1 pierces in such a manner that it is slidable free from the stretch of the central conductor 1 due to changes in the temperature to ensure the energizating between the central conductor 1 and the expansion chamber 21. This eliminates magnetic field due to passing current inside the expansion chamber 21. Therefore, inexpensive steel material can be used for parts for pressurization, a plate spring 23, an upper spring lock plate 24 and a ring nut 25.
