Photovoltaic cable having electromagnetic shielding effect and preparation method

Abstract

The invention discloses a photovoltaic cable with electromagnetic shielding effect and a preparation method thereof. The photovoltaic cable includes a wire core formed by twisting a plurality of tinned copper wires and a protective layer covering the wire core. The protective layer is from the inside to the outside. It is an electromagnetic shielding layer, an insulating protective layer and a wear-resistant and waterproof layer in sequence; the preparation method includes: firstly preparing the electromagnetic shielding layer material and the wear-resistant and waterproof layer material; Extrude the 180°C halogen-free flame-retardant photovoltaic cable irradiated insulating material onto the electromagnetic shielding layer, and carry out irradiation cross-linking to form an insulating protective layer; evenly coat the surface of the insulating protective layer with a wear-resistant and waterproof layer, dry, That is, the photovoltaic cable is obtained. The photovoltaic cable of the present invention not only has good electromagnetic shielding effect, but also has good flame retardancy and water resistance, greatly improves the service life of the photovoltaic cable, and has good application value and prospect.

Description

technical field [0001] The invention relates to the technical field of photovoltaic cables, in particular to a photovoltaic cable with electromagnetic shielding effect and a preparation method. Background technique [0002] Solar energy technology will become one of the green energy technologies in the future. Solar energy or photovoltaic (PV) is widely used in China, especially in recent years, as the production cost of polysilicon, the raw material of solar cells, has been greatly reduced, and the production technology of solar cells has been perfected day by day.

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 environments, and existing In this environment, the photovoltaic cables are not satisfactory in terms of weather resistance, ultraviolet resistance, ozone corrosion resistance and resistance to large temperature changes. Photovoltaic power plants need to replace cables frequently to ensure their own efficiency and stability. Greatly increased production costs, but also caused greater environmental pollution

Moreover, the electromagnetic shielding effect of the existing photovoltaic cables is poor. With the increase of the application of photovoltaic cables, more and more electromagnetic radiation will be brought, which will not only cause certain harm to the human body, but also electromagnetic interference will affect the transmission of signals
