It is made of polyamide fiber, etc. (3) is an outer cover that surrounds each component of the light guide, and is made of polyvinyl chloride, polyester elastomer, or the like. (4) and (5) are supporting metal fittings that serve as supporting parts for the light guide, with (4) being layered on the high-voltage charging part, and (5) showing being layered on the grounding part. (6)
is a space filled with an insulating compressed gas such as SF. Since the conventional light guide (10) is constructed and supported as described above, when the DC voltage of the high-voltage charging part is applied to the light guide, the voltage sharing of the light guide is due to the insulating material constituting the light guide. It will be determined by the insulation resistance value. This situation will be explained in detail with reference to FIG. Figure 2 equivalently shows the resistance distribution of each part of the light guide in the configuration shown in Figure 1. In this figure, (R1) is the creeping insulation resistance of the outer cover (3).
(RIa) + (Rib) is the insulation resistance of the outer cover part (3) in the penetrating direction, (R2) is the insulation resistance of the buffer material part (2), (
R,) is the insulation resistance of the core portion (1).

Moreover, this is not preferable because it causes a decrease in the creeping flash voltage of the light guide, and even if the voltage between the supporting metal fittings (4) and (5) is relatively low, flash faults are likely to occur.

もよいし２個以上設けてもよい。An embodiment of the present invention shown in FIG. 3 will be described below. In FIG. 3, (7) is a resistor disposed near the light guide (10), which has a resistance value about 1 to 3 times lower than the insulation resistance of the light guide (10). (Φ and (5) are the support devices that electrically connect the resistor and the light kite and serve as a support for both; 1 (4) is attached to the high voltage charging part, and (5) is the grounding device. (8) and (9) are connecting fittings for connecting the intermediate resistance position of the resistor and the intermediate position of the light guide at once. There may be one or two or more.

記の接続金具（８）。By making this arrangement, most of the leakage current when DC voltage is applied is transferred to the resistor (7), and the light guide remains as a high-resistance insulator, so the voltage in the creeping direction is reduced. Is the division of labor roughly equal? 1. Connection fittings (8) above.

における電圧の集中は非常に緩和されることになる。Since (9) is multiplied by 1, further equalization is achieved, and the concentration of voltage near the support fittings (4) and (5) as in the conventional case is greatly alleviated.

しイυるものである。In addition, in the above explanation, a resistor was cited as an example of a resistance member placed near the light guide, but it is not limited to this, and the insulation resistance is 1 to 3 Even if an extremely low-quality insulating material is used, a superior effect can be expected.

This prevents a drop in the single-circuit voltage, contributing to size reduction and improved reliability of the light guide.
