[0041] please see image 3 and Figure 4 , a cable used in a power system is characterized in that it includes a first conductor 11, a first insulating layer 21 covering the first conductor, a circular column outside the first insulating layer and covering the first The second conductor 12 of an insulating layer, the second insulating layer 22 that covers the second conductor, the third conductor 13 that is located outside the second insulating layer and wraps the second insulating layer in a circular column shape, is located in the third The shielding layer 4 outside the conductor, the outer sheath 5 that is extruded and coated outside the shielding layer; the ratio of the cross-sectional area of the first conductor to the cross-sectional area of the second conductor is [0.95, 1.05], the ratio of the cross-sectional area of the first conductor The ratio of the cross-sectional area to the cross-sectional area of the third conductor is [0.95, 1.05], the first conductor...
Embodiment 3
[0051] please see Figure 5 and Image 6, a cable used in a power system is characterized in that it includes a first conductor 11, a first insulating layer 21 covering the first conductor, and two arc-shaped columns outside the first insulating layer. The second conductor 12, the spacer bar 3 that is in the shape of a bow ring column between adjacent second conductors, the shielding layer 4 that wraps the second conductor and the spacer bar, and the outer sheath that is extruded and coated on the outside of the shielding layer Layer 5; the inner edge of the spacer and the inner edge of the second conductor are close to the outer edge of the first insulating layer, and the outer edge of the spacer and the outer edge of the second conductor are on the same cylindrical surface; the cross-sectional area of the first conductor and The ratio of the cross-sectional area of any second conductor is [0.95, 1.05]. The first conductor is twisted from a plurality of metal wires with ...
