Embodiment Construction

[0020] The technical solutions of the present invention will be described in further detail below through specific implementation methods.

[0021] Such as figure 1 As shown, a low-smoke, halogen-free, flame-retardant photovoltaic cable includes a conductive core 1 made of twisted tinned copper monofilaments, and a low-smoke, halogen-free, flame-retardant glass wrapped around the conductive core 1. The isolation layer 2 composed of cloth tape, the insulating layer 3 extruded outside the insulating layer 2 and the sheath layer 4 extruded outside the insulating layer 3, the pitch diameter ratio of the outermost layer of the conductive core is 9, and the conductive cores are each The pitch diameter ratio of the layer is increased by 2 in order from outside to inside. The insulating layer 3 is made of 150°C radiation cross-linked low-smoke halogen-free flame-retardant polyolefin material (model FPV120-1), and the sheath layer 4 is made of 150°C Composed of irradiation cross-linke...

Abstract

The invention provides a low-smoke zero-halogen flame-retardant photovoltaic cable which comprises a conductive wire core, insulating layers, an insulation layer, and a sheathing layer, wherein the conductive wire core is formed by twisting a plurality of tinned copper monofilaments; the insulating layers made of low-smoke zero-halogen flame-retardant glass fabric are wrapped on the conductive wire core in an overlapped manner; the insulation layer is extruded outside the insulating layers; the sheathing layer is extruded outside the insulation layer. The invention further provides a manufacture method of the low-smoke zero-halogen flame-retardant photovoltaic cable. The low-smoke zero-halogen flame-retardant photovoltaic cable and the manufacture method thereof have the advantages of scientific design, environmental protection, zero contamination, and wind, rain, ultraviolet and ozone corrosion resistance, and can bear temperature variation in a larger range.

Description

technical field [0001] The invention relates to the technical field of photovoltaic cables, in particular to a low-smoke, halogen-free, flame-retardant photovoltaic cable and a manufacturing method thereof. Background technique [0002] Under the influence of the financial crisis, the Chinese government regards the development of new energy as an important means of revitalizing the economy. There is no doubt that solar technology will become one of the green energy technologies in the future. Solar energy or photovoltaic (PV) is widely used in China, and building cost-effective and profitable photovoltaic power plants represents the most important goal and core competitiveness of all solar manufacturers. , and its profitability not only depends on the efficiency or high performance of solar modules, but also depends on its important power transmission tool - photovoltaic cables. However, most photovoltaic power plants are built in desert areas with extremely harsh environmen...
