る。Conventional technology Traditionally, this type of underwater motor has high insulation performance and is exposed to high-temperature water depending on the environment in which it is used, so it maintains heat resistance and water resistance over a long period of time. It is essential to use windings that can Below, conventional windings used in underwater motors will be explained. FIG. 2 shows an example of a conventional winding cross section for an underwater motor. In Figure 2, l is a copper conductor, 2 is an insulating layer made of polyethylene, and 3 is a polyester, formal, etc. provided between the copper conductor 1 and the insulating layer 2 to protect the insulating layer 2 from documents. The conductor shielding layer 4 is a sheath made of polyamide.
以上のように構成された水中モータ用巻線について、更

＋ｍｓ 〜２ 、０ ｍが適当である。The insulating layer 2 may be made of crosslinked polyethylene, crystalline polypropylene, or the like in addition to polyethylene. The film thickness is 0.2~ for a winding for a 200V underwater motor.
2.0M is common. When this insulating layer 2 is made of polyolefin resin, it is known that copper accelerates deterioration. In order to prevent this, a conductor shielding layer 3 is provided. Its constituent materials are mainly polyester resin,
Formal resin etc. are used and the conductor surface is coated with enamel. Its thickness is 0.01wa
~0.05mm is normal. Next, as the material used for the damage prevention sheath 4 during coil formation, polyamide resin with good slip properties is generally used, and the film thickness is 0 to 2.
+ms ~ 2.0 m is appropriate.
発明が解決しようとする課題
しかしながら、上記のような構成ではシース４゜絶縁層
２．導体遮蔽層３で絶縁性能を確保するためには最低０
．４ｍｍ〜０．５ｍの膜厚が必要となる。Problems to be Solved by the Invention However, in the above configuration, the sheath 4° and the insulating layer 2. In order to ensure the insulation performance of the conductor shielding layer 3, the minimum
．． A film thickness of 4 mm to 0.5 m is required.
ところが、損傷防止シース４にポリアミド樹脂のように
吸水性の樹脂を用いると、絶縁物としての機能は果たさ
ない。さらに、使用温度が高くなるとシース４が劣化し
、これが絶縁層２の課電状態に影響を与え、絶縁層２を
破壊し、巻線寿命が短くなるという問題があった。However, if a water-absorbing resin such as polyamide resin is used for the damage prevention sheath 4, it will not function as an insulator. Furthermore, when the operating temperature becomes high, the sheath 4 deteriorates, which affects the electrification state of the insulating layer 2, destroys the insulating layer 2, and shortens the life of the winding.
次に、絶縁層２の構成材料において、ポリエチレンや架

、９０℃での長期の使用には耐えないという問題があっ
た。また、結晶性ポリプロピレンでもそのポリマー状態
、変性状態、添加剤によって９０℃高温水中での使用の
可否が決定されるがその選択が困難である。Next, regarding the constituent materials of the insulating layer 2, polyethylene and crosslinked polyethylene have a heat resistance limit of about 70°C, and there is a problem that they cannot withstand long-term use at 90°C. Furthermore, whether or not crystalline polypropylene can be used in high-temperature water at 90° C. is determined by its polymer state, modified state, and additives, but selection is difficult.

。The third point is that the conductor shielding layer 3 has a high temperature (1
05°C to 200°C), but unlike when used underwater, the normal heat-resistant temperature cannot be used as a reference. Furthermore, in an environment of high temperature water (90°C), the influence of water cannot be ignored even if the insulating layer 2 is present, and the polyester resin becomes resistant to hydrolysis and loses its function as a conductor shielding layer. There is a problem in that resin deteriorates more rapidly than when used in the atmosphere.

The process of removing the sheath 4 largely depends on the skill of the individual, and even a small scratch can be fatal, so it requires a lot of man-hours.

It requires sealing of the windings and lead wires, including.

The polyamide-imide resin has a
Since it has good hydrolyzability and little deterioration even in high-temperature water (90°C), it acts as a conductor shielding layer for a long period of time. Rubber-modified polypropylene resin or polypropylene resin mixed with a rubber component has good flexibility and slipperiness on one surface and functions as a damage-preventing sheath. Furthermore, high insulation properties are guaranteed for long periods of time in high temperature water (90° C.). As a result, the damage prevention sheath can be eliminated, the film can be made thinner, and the space factor can be reduced. Moreover, since the work of peeling off the damage prevention sheath at the connection part is omitted, it can contribute to the simplification of the process.
