ものであった。Regarding the above-mentioned insulating spacer, there is a large area around the electric field relaxation electrode (4) due to the difference in thermal expansion coefficient between the lid resin (1) and the electric field relaxation electrode (4) during heating and cooling. Internal stress will occur. In particular, on the inner circumferential side of the 1L field relaxation electrode (4), there is a high possibility that peeling will occur at the interface between the composite RlXJ resin (1) and the electric field relaxation electrode (4), and this peeling will cause the conductor to When a high voltage is applied to (5), a corona is generated.In addition, the generation of internal stress around the electric field relaxation electrode (4) further reduces the mechanical strength of the pan-shaped spacer compared to the circular one. In addition, the 'electrode (4) for reconciling city boundaries is manufactured by bending a rod-shaped piece or one machined into an R-shape into a ring shape, so it has a complicated electrode shape. is difficult, has poor dimensional accuracy, and is expensive.
