Embodiment Construction

[0015] In order to easily understand the technical means, creative features, goals and effects of the present invention, the present invention will be further described below in conjunction with specific illustrations.

[0016] Such as figure 1 As shown, the photovoltaic cable with high waterproof performance includes a protective layer 1, a shielding layer 2, a waterproof layer 3, an insulating layer 4, a flexible protective layer 5, a cable core 6, and a connecting frame 7. There are multiple cable cores 6, and the cable core 6 is wrapped with an isolation layer 11, and there are multiple connecting skeletons 7 arranged at equal intervals along the length of the cable. Each connecting skeleton 7 is provided with the same number of perforations as the cable core 6, and the number of perforations is equal to that of the cable core 6. Not intersecting, each of the perforations is provided with a rubber pad 8 along the inner peripheral surface, the connecting skeleton 7 is sleev...

Abstract

The invention discloses a highly waterproof photovoltaic cable and belongs to the field of cables. The highly waterproof photovoltaic cable comprises a protective layer, a shielding layer, a waterproof layer, an insulating layer, a flexible protective layer, cable cores and connecting skeletons. The cable cores are wrapped in an isolation layer. The connecting skeletons are arranged at equal intervals along the length direction of the cable. Each connecting skeleton is provided with holes the number of which is the same as that of the cable cores and which do not intersect with one another. Each hole is provided therein with a rubber pad along the inner circumferential surface. The connecting skeletons sleeve the cable cores. The flexible protective layer wraps the cable, is filled with anelastic filler, and is made of a waterproof material. A gap is left among the plurality of cable cores to provide a space for the cable core deformation when the cable is bent, thereby improving thesoftness of the cable. Two waterproof structures are formed inside to improve a waterproof effect.

Description

technical field [0001] The invention relates to a photovoltaic cable with high waterproof performance, which belongs to the field of cables. Background technique [0002] Cables are indispensable and important equipment for circuit connection and power transmission. In view of the actual use of cables, there are certain requirements for the waterproof performance and flexibility of cables. [0003] An existing photovoltaic cable has a plurality of cable cores wrapped inside. The multiple cable cores are arranged together in the cable and the cable cores are in contact with each other. There is no space reserved between the cable cores. When the cable is bent, the space is limited. The mutual restriction between the cable cores leads to insufficient flexibility and inconvenient laying. Moreover, there is only one waterproof layer inside the existing cable, which cannot provide protection for the inner cable core after damage, and the waterproof performance is limited. Conte...
