[Detailed Description of the Invention] The present invention relates to the improvement of insulated wires that require radiation resistance, such as those used in fast breeder reactors of nuclear reactors.

Conventionally, radiation-resistant insulated wires have been made by winding a glass mica tape as an insulating layer on a conductor and having a pressing layer of glass braid on top of that, or by wrapping an inorganic wire such as Al 2 O 3 or MgO on the conductor. It is known that a powder layer is provided and a metal protection tube is provided on top of the powder layer.

However, in the former case, when the atmospheric humidity is high, moisture easily enters the wire, resulting in a disadvantage that the insulation performance of the wire is significantly reduced. In the latter case, since the outermost layer has a metal protection tube, it is better than the former in terms of moisture resistance, but there is a possibility that moisture may infiltrate from the wire terminals, and if moisture gets inside the wire, it will eventually become damaged. This causes the same difficulties as the former.

As a result of intensive studies in view of the above points, the present invention solves the above problems by having a coating layer of polyetheretherketone on the conductor and an inorganic insulating layer on the coating layer. The idea has been completed.

In this invention, the polyetheretherketone coated directly on the conductor 1 has the general formula It is an organic polymer material shown in The reason for coating the conductor with the above-mentioned polymer material is that, according to research by the present inventors, polyether ether ketone has better radiation resistance than other polymer materials, and can withstand radiation of about 10 10 R. This is because it has excellent adhesion to the conductor when it is extruded and coated onto the conductor 1.

Further, the inorganic insulating layer 3 on the polyetheretherketone coating layer 2 used in the present invention is as follows:
Mica tape, glass mica tape, etc. wound with an inorganic tape, or
An inorganic powder layer such as Al 2 O 3 or MgO is selected. When the inorganic insulating layer 3 is composed of a wound layer of an inorganic tape, the protective layer 4 of the inorganic insulating layer 3 may be a glass braided layer or a glass fiber wound horizontally on the inorganic insulating layer 3, or the inorganic tape. The insulating layer 3 may be coated with the aforementioned polyether ether ketone by extrusion, etc. as appropriate. When the inorganic insulating layer 3 is made of inorganic powder, it is preferable to use a thin pipe made of stainless steel or the like as the protective layer in terms of manufacturing efficiency.

The insulated wire of the present invention can be easily manufactured by extruding polyetheretherketone onto the conductor using an ordinary extruder, and then winding a tape made of an inorganic material as an inorganic insulating layer using an ordinary taping machine. can be manufactured. Furthermore, if necessary, a glass fiber protective layer can be provided on the inorganic insulating layer using a braiding machine or a taping machine, or a polyether ether ketone protective layer can be provided using an extrusion machine. When using inorganic powder as the inorganic insulating layer in the present invention, a polyetheretherketone coating is inserted into the center of a metal pipe such as a stainless steel pipe having an inner diameter larger than the outer diameter of the coating, and the void is It can be manufactured by filling a container with inorganic powder.

As mentioned above, the radiation-resistant insulated wire of the present invention is coated with polyetheretherketone, which has good radiation resistance and good adhesion to the conductor, directly above the conductor, so water or moisture does not enter the conductor. This prevents deterioration of the insulation performance of the electric wire, and the coating layer does not suffer from radiation deterioration.
Furthermore, since it has an inorganic insulating layer on the polyetheretherketone coating layer, it has particularly excellent radiation resistance.
