The power core 10, control core 20, and auxiliary core 30 are filled with PP filler rope 60 to maintain a round shape when the cable is coiled.

[0023] The power core 10 includes a power core conductor 11, which is a fifth type of soft conductor. A power core insulation layer 12 is extruded on the outer circumferential surface of the power core conductor 11.

[0024] The control core 20 includes multiple control core conductors 21, and the outer sides of the multiple control core conductors 21 are extruded with a control core inner layer 24. The control core conductors 21 are made of a mixture of fiber filaments and a sixth type of soft copper wire.
