Photovoltaic electric cable for switching between the wind power and solar power

Abstract

The invention discloses a wind and solar energy conversion photovoltaic cable and manufacturing method thereof, which is object to allow the photovoltaic cable to have characteristics of easy laying, environmental protection, anti-ozone and ultraviolet light, moisture-proof, grease-proof, flame resistance, corrosion resistance, wide temperature range width, as well as anti-electromagnetic interference. To solve the above technical problems, the invention adopts the following technical projects: a wind and solar energy conversion photovoltaic cable includes including the insulated wire core, wherein, the insulated wire core is a copper conductor coated with an irradiated cross-linked low smoke zero halogen insulation layer, and the outer layer of the insulated wire core is in sequence concentrically wrapped with a glass fiber tape, a metal shield layer, a water blocking tape and an irradiated cross-linked low smoke zero halogen jacket. Compared with the prior art, the temperature range of the inventive cable can reach the temperature range from +150 DEG C to -45 DEG C, the laying temperature of the cable is not lower than -30 DEG C, and the cable has a long service life, and all indexes of the cable are in line with the RoHS environmental standards.

Description

technical field [0001] The invention relates to a photovoltaic cable for wind energy and solar energy conversion and a manufacturing method thereof. Background technique [0002] At present, with the enhancement of human awareness of environmental protection, the world's energy structure is also undergoing tremendous changes. my country's wind energy and solar energy resources are very rich, and the market prospects for wind power and solar power generation are broad. As the power generation method with the most mature technology, the most large-scale development conditions and the most promising commercialization development among new energy sources, the development speed of wind power and solar power is impressive. At present, mineral resources such as coal and oil in China are gradually exhausted. Wind power and solar energy are one of the most mature and most suitable for large-scale development and commercial development in the field of renewable energy. At the same tim...

Problems solved by technology

However, the existing photovoltaic cable production technology, such as the Chinese invention patent application date of October 29, 2008, application number 200810045404.7, is a method for manufacturing power cables for solar photovoltaic power generation equipment. The manufacturing steps include material selection-drawing-conductor stranding Composite—isolation layer wrapping—insulation layer extrusion—insulation layer radiation crosslinking treatment—outer sheath extrusion—outer sheath radiation crosslinking treatment—finished product. In the disclosed technical scheme, the cable only has weather resistance , UV radiation resistance and ozone erosion resistance, the highest temperature resistance is +120 ° C, and does not contain multi-core cables, not only the adaptability is not comprehensive enough, but the temperature resistance range is also narrow, it is difficult to adapt to various environments and environmental protection requirements
