ある。(Prior art) OF cables often have a rubber molded body used in contact with electrical insulating oil, such as a backing, as an accessory.For example, the backing of this village has an important function of sealing the insulating oil. Therefore, they are generally made from fluoro rubber or nitrile rubber, which have excellent oil resistance, heat resistance, and sealing properties. Among these backings using rubber, those in the form of O-rings or F backings for semi-permanently sealing with insulating oil have only the sealing surface in contact with the insulating oil, but when the OF cable connection is assembled, Spilling oil 1; The backing mounted on the target is in full contact with the oil. Although both fluororubber and nitrile rubber have been put to practical use as O-rings, soft and inexpensive nitrile rubber is preferred for backings in shapes other than O-rings.

わり、大掛かりな開発を必要とする。However, in either case, some of the substances in these rubber molded bodies dissolve in the insulating oil, reducing the insulation properties of the insulating oil and causing dielectric breakdown of accessories in which these rubber molded bodies are used. This has the drawback of causing deterioration of Tan δ and ρ in particular. This tendency is greater for nitrile rubber than for fluororubber, but as already mentioned, fluororubber is inferior in terms of sealability and cost. Furthermore, if the composition in the rubber is changed to avoid this, the physical properties of the rubber and the manufacturing method will change, requiring large-scale development.

の処理方法を提供することにある。(1st objective of IJ+) The 1st objective of IJ1 is to provide a method for processing a rubber molded article that can prevent the deterioration of the insulation properties of oil without changing the rubber composition. .

理用絶縁油中て加熱処理することを特徴としている。(Structure of the Invention) The method for treating a rubber molded article according to the present invention is a method for treating a rubber molded article that is used in contact with electrical insulating oil. It is characterized by heat treatment in substantially insulating oil for rolling treatment.

The decrease can be suppressed.

絶縁油の絶縁特性を低下することがなくなる。(Example) As already mentioned, in Unreleased II, a rubber molded product used in contact with electrical insulating oil, such as a backing for an OF cable, is used after molding and before use. The method is to heat-treat the insulating oil in substantially the same treatment insulating oil as the insulating oil to be treated. However, since there is a limit to the amount of oil contaminants that can be contained, the rubber molded body is heated in insulating oil for treatment as described in 4-1 to remove oil contaminants. Once it is completely dissolved into the insulating oil for treatment, the insulating oil will no longer deteriorate. Therefore, even if the rubber molded article treated in this manner is brought into contact with the insulating oil that is actually used, the insulating properties of the insulating oil will not deteriorate.

設定されなければならない。In this case, it should be noted that the conditions for the heat treatment must be set so as not to deteriorate the properties of the rubber molded body itself.

Table 1 shows the results of comparing the properties (rate of change in elongation) of the rubber molded body itself.

f + 6 0.010 ÷ 1.0 As can be seen from Table 1 above, if the treatment is carried out under the conditions indicated in -, the deterioration of the properties of the rubber molded body or insulating oil will be significantly reduced.
Further, the decrease in physical properties remains at a level that poses no practical problem. It was confirmed that this treatment also applies to fluororubber and neoprene rubber other than nitrile rubber.

。(Effects of IJ1) According to the unreleased IJ+, as shown in "-", oil contaminants in the rubber molding dissolve into the insulating oil for processing and come into contact with the insulating oil actually used. It is possible to suppress the deterioration of the insulating properties without contaminating the insulating oil, and therefore, there is a practical benefit of being able to use inexpensive nitrile rubber.
