ある。 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.

る。 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 has better moisture resistance than the former, but the wire itself has poor flexibility, making it difficult to work when constructing the wire.
