Claims

[Scope of Claim for Utility Model Registration] In a cylindrical cut-out in which a fuse tube is installed in a fuse tube insertion hole of a cylindrical body insulator, the lower part of the body insulator bulges laterally and communicates with the fuse tube insertion hole. and forming a bulge opening at the lower part thereof, and on the outside of the bulge, arcing horns attached to the middle part of the main insulator with a fitting are arranged at predetermined intervals, An intermediate electrode facing the arcing horn is mounted on the circumferential wall of the bulge, and a current limiting unit containing a non-linear resistor is disposed within the bulge, and a current limiter is provided at the top of the bulge through the upper electrode. In addition to supporting and fixing, a discharge gap is provided between the upper electrode and the lower electrode provided in the fuse tube insertion hole, and the lower electrode of the current limiting unit and the intermediate electrode are connected by a conductor. A partition is provided in the bulge to cover the outer periphery of the current limiting unit between the bulge and the bulge, and a filler is filled in the space between the current limit unit and the partition and the bulge. A cylindrical cut-out with a distinctive feature.
