Embodiment 1

[0023] please see figure 1 , the signal cable core 1, the overall wrapping layer 2, a pair of power wires 3, the ground wire 4 and the outer sheath 5 are given, and the power wire 3 and the ground wire 4 are located between the signal cable core 1 and the overall wrapping layer 2 , The outer sheath 5 is located outside the total wrapping layer 2 .

[0024] The signal cable core 1 includes a group of signal cores 11 each coated with a coating 111, a dragging layer 12 and a wrapping layer 13. The number of signal cable cores 11 is four, and these four signal cable cores 11 form a star-quad group , that is to say, four signal cable cores 11 are twisted at a pitch of 200mm to form a star-quad group. Each signal core 11 is formed by twisting a plurality of thin tinned copper wires, and the diameter of each thin copper wire is 0.3 mm. The aforementioned covering layer 111 is cross-linked polyethylene. The drag cladding 12 adopts a polypropylene tape (i.e. adopts a foamed PP ...

Embodiment 2

[0030] As shown in the figure, only the stranding pitch of the four signal cores 11 is changed to 350mm; the diameter of the tinned copper wire that constitutes the signal core 11 is changed to 0.12mm; The diameter of the tinned copper wire of the conductor 31 is changed to 0.5 mm; the diameter of the tinned copper wire constituting the ground wire 4 is changed to 0.3 mm. All the other are the same as the description to embodiment 1.

Embodiment 3

[0032] The picture is omitted, only the twisted pitch of the four signal cable cores 11 is changed to 100mm; the diameter of the tinned copper wire forming the signal core 11 is changed to 0.5mm; the thickness of the aluminum foil is changed to 0.035mm; The diameter of the tinned copper wire of the conductor 31 is changed to 0.12 mm; the diameter of the tinned copper wire constituting the ground wire 4 is changed to 0.28 mm. All the other are the same as the description to embodiment 1.

Abstract

A cable for solar power generation belongs to the technical field of wires and cables. The cable comprises a signal cable core, an overall lapped covering, a pair of power wires, an earth wire and an outer sheath, and the outer sheath is positioned outside the overall lapped covering. The cable is characterized in that: the signal cable core comprises a group of signal cores, a wrapping layer anda lapped covering, each signal core is covered by a covering layer, the signal cores are wrapped by the wrapping layer, the wrapping layer is lapped by the lapped covering, wherein the four signal cores are formed into a star quad, the colors of the covering layers of the signal cores are different, both the lapped covering and the overall lapped covering are aluminium foils, the outer sheath is thermoplastic elastomer, and the power wires and the earth wire are positioned between the lapped covering and the overall lapped covering. The cable has the advantages that: the overall structure is compact, the cable has ideal twisting resistance, and the service life of the cable can be prolonged; and the cable has excellent anti-ultraviolet property, high temperature-resistant property and twist-resistant property and is environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of electric wires and cables, and in particular relates to a cable for solar power generation, which is used for signal control connection of solar power generation equipment. Background technique [0002] With the rapid improvement of human productivity, energy consumption is also increasing, resulting in a sharp deterioration of the regional environment and the global environment, for example, a series of impacts such as global warming caused by the greenhouse effect, melting of icebergs, glaciers, and sea level rise The global environmental factors on which human beings depend have become the focus of attention of the international community. As we all know, the emission of greenhouse gases is mainly due to the massive consumption of mineral energy such as coal, oil and natural gas by human beings. Therefore, while developing the economy, countries have made energy conservation and full utilization of ene...
