も旨くなる欠点があった。Conventionally, the linear bushing shown in FIG. 1 is easy to process and inexpensive, but it has had the disadvantage that when the normal pressure becomes high, the creeping pressure is no longer proportional to the linear distance, and sufficient pressure resistance cannot be obtained. In addition, the "Hidai" bushing shown in Figure 2 has good creeping pressure resistance, but due to the manufacturing process, there is a large difference between the inner and outer diameters, and it is necessary to cut a long cylindrical insulator, making it difficult to process and expensive. was there.

ブッシングである。Hereinafter, the present invention will be explained with reference to FIG. 3. A linear high normal pressure bushing outer cylinder I is equipped with a VC rubber backing 4 and an insulator flange 5, and the surface pressure of the rubber backing 4 blocks the linear creeping surface. This is a high-voltage bushing with Hidai I bushing.
