Abstract
The invention discloses a cable with uniformly distributed electric cores, which comprises a wrapping layer, wherein three phase line electric cores with the same shape are arranged in the wrapping layer, and the phase line electric cores are uniformly distributed in a cylindrical space formed by closing the wrapping layer around the axis of the wrapping layer.

In order to reduce the outer diameter of the cable, three phase lines are pressed into a fan-shaped structure, and the zero line and the ground line are made into a circular structure. Because three phase lines and a zero line, a ground wire is in the same cable core, and the positions of the three phase lines are in an asymmetric structure.
The disadvantages are that: 1. the magnetic fields generated by the three phase lines during the power-on operation can generate induced currents in the zero line and the ground line, namely, the alternating current impedance is increased. And further, the circuit loss is generated in the process of power transmission, and energy is wasted.
2. The stress field existing in the cable core of the cable is asymmetrical, and the cable is twisted and snakelike in the process of production, manufacturing, laying and installation due to asymmetrical stress, so that quality accidents such as insulation, cracking of a sheath layer and the like are caused.
3. Conventional low-voltage power cable products are only suitable for alternating current power frequency power supply systems. Is not suitable for an alternating current high-frequency or variable-frequency power supply system.
4. The conventional low-voltage power cable product has a large external diameter ratio and high installation and laying cost.
