[0029] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0030] Example: Figure 1-4 As shown, this utility model provides a technical solution: an anti-oxidation insulated aluminum alloy photovoltaic cable, comprising three conductors 1, an insulating bushing 2 sleeved on the outside of the conductors 1, a support tube 3 snapped between two adjacent conductors 1 inside the insulating bushing 2, and an insulating flame-retardant and anti-breakage mechanism 4 provided on the outside of the insulating bushing 2. The insulating flame-retardant and anti-breakage mechanism 4 includes an inner reinforcing mesh 401, an insulating layer 402, a flame-retardant layer 403, a positioning collar 404, reinforcing ribs 405, and an outer reinforcing mesh 406.

[0031] An inner reinforcing mesh 401 is sleeved on the outside of the insulating bushing 2. An insulating layer 402 is sleeved on the outside of the inner reinforcing mesh 401. A flame-retardant layer 403 is sleeved on the outside of the insulating layer 402. In order to achieve both insulation and flame-retardant effects as well as increase the anti-oxidation effect, the insulating layer 402 is filled with polyvinyl chloride, and the flame-retardant layer 403 is filled with polytetrafluoroethylene.

[0032] Positioning collars 404 are equidistantly engaged between the insulating layer 402 and the flame-retardant layer 403, and reinforcing ribs 405 are equidistantly engaged inside the positioning collars 404.

[0033] An outer reinforcing mesh 406 is sleeved on the outside of the flame-retardant layer 403. In order to facilitate the reinforcement of the insulation layer 402 and the flame-retardant layer 403, an embedding groove is provided on the outside of the insulation layer 402 and the inner wall of the flame-retardant layer 403 at the position corresponding to the outside of the positioning collar 404. The inner reinforcing mesh 401 and the outer reinforcing mesh 406 are both welded by metal wires.

[0034] An anti-oxidation filling mechanism 5 is provided on the outside of the outer reinforcement mesh 406. The anti-oxidation filling mechanism 5 includes an outer sheath 501, an aluminum alloy armor layer 502, a positioning groove 503, a limiting ring 504, an anti-oxidation wear-resistant sleeve 505, and a filling cotton pad 506.

[0035] The outer reinforcement mesh 406 is fitted with an outer sheath 501, and the outer sheath 501 is fitted with an aluminum alloy armor layer 502.

[0036] The outer sheath 501 has equidistant positioning grooves 503 on its outer side, and the inner wall of the aluminum alloy armor layer 502 is equidistantly engaged with the positioning rings 504 at the positions inside the positioning grooves 503. In order to improve the anti-oxidation effect, and because the outer sheath 501 is made of cross-linked polyolefin, the outer side of the positioning rings 504 is in contact with the inner wall of the positioning grooves 503.

[0037] An anti-oxidation and wear-resistant sleeve 505 is fitted onto the outer side of the aluminum alloy armor layer 502, and filling cotton pads 506 are equidistantly snapped onto the inner wall of the anti-oxidation and wear-resistant sleeve 505.

[0038] The working principle and usage process of this utility model are as follows: First, the conductor 1 is supported and limited by the support tube 3 to ensure the stability of the conductor 1 inside the insulating bushing 2. Then, the cooperation of the insulating layer 402 and the flame retardant layer 403 not only improves the insulation and flame retardant performance of the cable, but also ensures the anti-oxidation effect. Furthermore, the positioning collar 404 and the reinforcing rib 405 are filled between the insulating layer 402 and the flame retardant layer 403 to improve the springback effect of the insulating layer 402 and the flame retardant layer 403 after bending. In addition, the insulating layer 402 and the flame retardant layer 403 are wrapped with the inner reinforcing mesh 401 and the outer reinforcing mesh 406 to increase the strength of the insulating layer 402 and the flame retardant layer 403 and prevent the phenomenon of breakage when bending.

[0039] Finally, the positioning groove 503 and the limiting ring 504 work together to limit the aluminum alloy armor layer 502, improving the stability of the aluminum alloy armor layer 502 on the outer sheath 501 and preventing misalignment after bending. Then, the aluminum alloy armor layer 502 is covered by the anti-oxidation and wear-resistant sleeve 505, which further improves the anti-oxidation performance of the cable and increases its service life. In addition, the filling cotton pad 506 fills the anti-oxidation and wear-resistant sleeve 505 to prevent collapse and deformation when pressed.
