[0047] An energy-saving transmission cable as described in any of the above-mentioned embodiments is characterized in that the inner conductor is formed by twisting conductive wires or casting from molten conductive liquid or stretching from a conductor rod with a large cross-section.

[0052] An energy-saving transmission cable as described in any of the above-mentioned embodiments is characterized in that the outer conductor is formed by twisting conductive wires or casting from molten conductive liquid or stretching from a conductor rod with a large cross-section.

[0053] The energy-saving power transmission cable described in any of the above-mentioned embodiments is characterized in that in each engaging unit, the upper engaging body 12, the engaging conductor cavity 14 and the lower engaging body 13 are parallel to each other.

[0054] The energy-saving power transmission cable described in any of the above-mentioned embodiments is characterized in that in each engaging unit, the height of the upper engaging body 12 is equal to the height of the lower engaging body 13 .

[0055] The energy-saving power transmission cable described in any of the above-mentioned embodiments is characterized in that in each engaging unit, the bisector of the height of the engaging conductor cavity 14 does not pass through the axis of the inner cavity 17 of the energy-saving body.

[0056] In the present application, the spiral conductor 3 is an integrated structure and the inner cavity 17 of the energy-saving body is tightly attached to the outside of the inner sheath 4, and one end of the spiral conductor 3 is located in the first locking cavity 16, so that the spiral conductor 3 can be stretched out or inserted, which not only increases the cross-sectional area of ​​the spiral conductor 3, but also allows the spiral conductor 3 of the required cross-sectional size to be placed, which is extremely convenient for replacement and recycling when damaged or partially defective; in the present application, the inner sheath 4 is coated on the outside of the inner conductor 5 and can actually be an insulated wire. In this way, the cross-section of the inner conductor 5 can be flexibly changed and the outer diameter of the inner sheath 4 can be flexibly changed by changing the diameter of the inner conductor 5 and the thickness of the inner sheath 4. That is, the conductivity of the inner conductor is variable and the diameter of the inner sheath 4 is variable. If the spiral conductor 3 coated on the outside of the inner sheath 4 is tangent to the inner wall of the energy-saving wall 11, the spiral conductor 3 and the inner sheath 4 can be kept fixed and the structure is stable. If there is a gap between the spiral conductor 3 and the inner wall of the energy-saving wall 11, the position of the spiral conductor 3 can also be relatively fixed and have better heat dissipation performance. In the present application, a snap-in conductor 2 is placed in the snap-in conductor cavity 14 to increase the conductivity. The snap-in conductors 2 in different snap-in conductor cavities 14 can be used alone or in combination with the snap-in conductors 2 in other snap-in conductor cavities 14 to improve the transmission capacity of a single-channel electric energy.

[0057] In the present application, the filling component in the outer conductor cavity is plastic or a conductor or an insulated wire with a conductor inside; the filling component not only plays a filling role, but also makes the cable as a whole more round and the structure more stable; when the filling component is a conductor, the conductor can be cast or drawn; when the filling component is an insulated wire with a conductor inside, the conductor can be cast or drawn, and the insulating plastic is extruded and coated on the outside of the conductor to form an insulated wire; the presence of the conductor increases the power transmission capacity.

[0058] The outer conductor 8 in the present application is located in the filling component and can be used to transmit both power and electrical signals.

[0059] In the prior art, three insulated wires are required to transmit three-phase electricity. Usually, the three insulated wires are placed in a triangle and wrapped with a protective layer. On the one hand, this method occupies a large space, and on the other hand, it consumes more materials. The structure in the present application allows the inner conductor, the spiral conductor, and the snap-fit ​​conductor to cooperate with each other, and the purpose of transmitting at least three-phase electricity is also achieved, and the diameter is smaller and the space resources are more saved; the space is effectively utilized, and the material consumption is reduced; the spiral conductor is retractable and replaceable and easy to recycle, and the cross-sectional area can be flexibly changed, so different current-carrying capacity requirements can be met; the snap-fit ​​conductors can be combined as needed to achieve large current transmission, and part of them can be left as ground wires; therefore, the purpose of saving resources and energy is achieved in the present application.

[0060] Although there are solutions for ring conductors in the prior art, they cannot achieve the function of the spiral conductor in the present application; in the present application, the existence of the first locking cavity 16, the energy-saving body inner cavity 17, and the locking conductor cavity 14 makes the conductor's heat dissipation ability stronger, that is, under the premise of transmitting the same power load, the temperature of the cable in the present application is lower; in other words, at the same rated operating temperature, the current carrying capacity of the cable in the present application is larger, so the cross-sectional area of ​​the conductor can be relatively reduced, so the present application achieves the beneficial technical effect of more energy and material saving.

[0061] In the present application, when the current carrying capacity of the inner conductor is sufficient, the current carrying capacity of the cable can be changed after it is formed by adjusting the spiral conductor and combining the clamping conductors; and the conductor replacement is more convenient, and when the conductor is partially damaged, there is no need to replace the entire cable.

[0062] The present invention has the following major beneficial effects: smaller diameter, more space resource saving, greater current carrying capacity, less material consumption and lower cost.

[0063] The above embodiments are only preferred technical solutions of the present invention and should not be regarded as limiting the present invention. The protection scope of the present invention shall be the technical solutions recorded in the claims, including the equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present invention.
