Double-core tensile rat-proof anti-termite separable photovoltaic cable with rated DC voltage of 1800V

Abstract

The invention discloses a double-core tensile rat-proof anti-termite separable photovoltaic cable with a rated DC voltage of 1800V. The double-core tensile rat-proof anti-termite separable photovoltaic cable comprises two wire cores, a connecting rib and a sheath layer, wherein the two wire cores are connected through the connecting rib, and the sheath layer coats the wire cores to form a cable with cross section in a dumbbell shape; each wire core comprises a conductor layer and an insulating layer; and each conductor layer is composed of a conductor wire and a reinforcing wire, and each insulating layer coats the corresponding conductor layer. The double-core tensile rat-proof anti-termite separable photovoltaic cable can be easily torn along the connecting rib, is convenient in installation, and is low in production and installation costs.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a double-core tensile, rodent-proof and ant-proof separable photovoltaic cable with a rated DC voltage of 1800V. Background technique [0002] With the development and utilization of solar energy, photovoltaic power generation has become the main way to develop solar energy. Solar photovoltaic power generation is a clean, environmentally friendly, green and safe renewable energy. At present, the development and utilization of solar power generation has become an important strategic decision for the sustainable development of many countries in the world. The construction of large-scale solar photovoltaic power stations has brought unlimited business opportunities to photovoltaic cable manufacturers. As a key transmission component of solar photovoltaic power generation systems, photovoltaic cables play a vital role in the utilization of solar energy. [0003] The current photovol...

Problems solved by technology

[0003] The current photovoltaic cables are all single-core structures. After installation and laying, the positive and negative poles are suspended and separated under the solar panel, and the scattering looks messy, which affects the appearance.

At the same time, photovoltaic power stations are getting bigger and bigger, and the distance of laying photovoltaic cables is getting bigger and bigger. The larger the laying distance, the greater the tension on the photovoltaic cables themselves, and it is very easy to cause conductors to be thinned or broken. Photovoltaic power stations are now built on barren mountains and Gobi Desert, where there are more rodents and ants, which will cause damage to cables
