Embodiment 1

[0066] please see Figure 1 to Figure 8 , a power cable, with a strengthening part 1, six accommodating parts 3 distributed on the outer edge of the strengthening part, a protective layer 4 located outside all the accommodating parts, and an outer sheath 5 wrapped outside the protective layer, each There is a power transmission part 2 inside the accommodating part; it is characterized in that the accommodating part 3 is composed of a third bending part 31, a second connecting part 32, a fourth bending part 33, a third connecting part 34, and a fifth bending part connected in sequence. part 35, there is a second cavity 30 between the third bending part 31 and the fifth bending part 35, if the fifth bending part is not connected to the third bending part, the fifth bending part is not connected to the first bending part There is a fourth cavity 37 between the fourth bending part 33 and the fifth bending part 35, a third cavity 36 between the second connecting part 32 and the fif...

Embodiment 2

[0092] please see Figure 9 , and refer to Figure 1 to Figure 8 , a power cable, basically the same as the implementation example 1, the difference is that: the opening ends of the second cavity are distributed along the same direction; Figure 9 The distribution can be clockwise or counterclockwise.

[0093] The power cable described above is characterized in that the lower surface of the first curved part of the first curved part in the second cavity is located above the lower surface of the third connecting part; the lower surface of the first curved part can also be connected to the third connecting part. The lower surfaces of the parts are in the same plane, which increases the area of ​​the first bending part, that is, the area of ​​the conductor, that is, the conductive capacity.

Embodiment 3

[0095] please see Figure 10 , and refer to Figure 1 to Figure 9 , a power cable, basically the same as the implementation example 1, the difference is that: there are three accommodating parts 3 outside the reinforcing part 1, and each accommodating part has a power transmission part 2 inside, and the three accommodating parts of the inner ring are outside The part is the same as that of implementation example 1.

[0096] Certainly, there may be multiple accommodating parts for the inner ring.

[0097] Of course, the distribution of the opening ends of the second cavities of the housing parts of the inner ring can also be distributed in the same direction as in Example 2, or not in the same direction; similarly, the distribution of the second cavities of the housing parts of the outer ring The distribution of the opening ends may also be distributed along the same direction as in Embodiment 2, or may not be distributed in the same direction.

[0098] This implementation e...

Abstract

The invention belongs to the technical field of electric power and cables, and relates to a power cable. The power cable is provided with a reinforcing component, an accommodating component, a protective layer and an outer protective layer, and a power transmission component is arranged in the accommodating component. The power cable is characterized in that the accommodating component is composed of a third bent part, a second connecting part, a fourth bent part, a third connecting part and a fifth bent part; a second cavity, a fourth cavity and a third cavity are formed in the accommodating component; the third cavity and the second cavity are communicated with each other; the third cavity and the fourth cavity are communicated with each other; the accommodating component is of an integrated structure; the power transmission component is composed of a first bending part, a first connecting part and a second bending part, and a first cavity is formed among the first bending part, the first connecting part and the second bending part; and the second bending part is arranged in the fourth cavity, the first connecting part is arranged in the third cavity, and the first bending part is arranged in the second cavity. The invention also discloses a communication optical cable, a photoelectric composite cable and an optical fiber ribbon. The power cable of the invention has the advantages of simple structure, easy stripping, good heat dissipation, lighter weight, lower cost and more flexible use.

Description

technical field [0001] The invention belongs to the technical field of electric power, cable and communication, and in particular relates to a power cable, a photoelectric composite cable, a communication optical cable and an optical fiber ribbon. Background technique [0002] In the prior art, cables are twisted with round insulated wires, optical cables are twisted with round loose tubes, etc., which cause great damage to conductors, optical fibers or optical fiber ribbons, and require complex cabling equipment; the product has a large diameter and high cost; And the stripping of the conductor and the optical fiber ribbon is cumbersome, the efficiency is low, and the heat dissipation effect of the conductor is poor. [0003] CN201408278U discloses a kind of optical fiber cable for highly flexible drag chain. Including: optical fiber, optical fiber sheath, optical fiber unit sheath, FRP (fiber reinforced plastic) reinforcement, non-woven wrapping, inner sheath, reinforceme...
