可撓性に富むことから絶縁電線の可撓性も良好である。This polyethylene insulated wire is widely used in power cables, communication cables, etc. due to the excellent electrical insulation and high frequency properties of polyethylene, and since polyethylene itself is highly flexible, the insulated wire has good flexibility. It is.

Insulated wires with so-called engineering plastics such as EEK), polycarbonate (PC), and polysulfone as the insulating layer may be considered, but these have good trauma resistance, but have poor flexibility when made into wires, and are difficult to bend. It has the disadvantage of poor workability. Furthermore, since engineering plastics have polar groups in their molecules, they are relatively water-absorbing, and they also have the disadvantage that their voltage resistance characteristics decrease when used under water immersion conditions for a long period of time.

フィンであるので、耐外傷性も比較的良好となる。In the insulated wire having such a structure, since the insulating layer has a two-layer structure, the thickness of each insulating layer can be made thin, resulting in good flexibility. Because it has a layered structure, even if there is a defect such as a pinhole in each insulating layer, their positions will hardly overlap, so compared to a single layer structure, even if the thickness is the same, The insulation properties are good.Furthermore, since the outside is made of crosslinked polyolefin, the trauma resistance is also relatively good.

This prevents a decrease in

A first insulating layer 2 made of engineering plastic is provided on a layer 3. In the insulated wire of this example, the insulating layer 3 made of engineering plastic, which has good resistance to external damage, is disposed on the surface, so that the resistance to external damage is even better. Moreover, since the second insulating layer 3 as the inner layer is made of crosslinked polyolefin with improved heat resistance, the second insulating layer 3 is deformed by this heat even when extrusion coating engineering plastics whose extrusion coating temperature is high. The first insulating layer 2 can be formed without any problems (the first insulating layer 2 can be formed).Furthermore, although the first insulating layer made of a water-absorbing engineering plastic is present as an outer layer, the water absorbed here is Since it does not penetrate into the second insulating layer 3 made of crosslinked polyolefin on the inside, the drop in insulation voltage is slight even if it is used in a submerged state.

It has a three-layer structure in which one insulating layer 2 is provided, and a second insulating layer 3 made of crosslinked polyolefin is further provided on this second insulating layer 2.
