Problems solved by technology
If a conventional cable is used as a substitute, the cable insulation layer may be damaged due to insufficient cable sheath strength, thereby affecting the service life of the entire cable, and even causing dangers such as short circuit and fire; and the traditional photovoltaic cable can no longer meet the existing complex requirements. The use environment, when the photovoltaic cable is used outdoors, it is often eaten by mice and termites, which affects the performance of the photovoltaic cable to varying degrees
If the sheath is damaged, the sheath cannot protect the insulation

Embodiment
[0025] An environmentally friendly multi-core photovoltaic cable in this embodiment includes a core body, an insulating layer and a flame-retardant layer, the insulating layer is arranged between the flame-retardant layer and the core body, and the insulating layer uses methyl vinyl silicone rubber as the base material It is made of different materials, the outside of the flame-retardant layer is provided with a mouse and ant protection layer, and the outside of the mouse and ant protection layer is covered with an outer sheath layer.
[0026] The flame-retardant layer is a halogen-free low-smoke flame-retardant layer, which is prepared from the following raw materials in parts by mass: polyolefin resin: 100 parts; ethylene-vinyl acetate-maleic anhydride terpolymer: 15-20 parts; phosphorus Nitrogen-based flame retardant: 40-70 parts; flame-retardant synergist: 10-20 parts.
[0027] A fiber braiding layer is arranged outside the core body, which is used as a strengthening struc...

Abstract
The invention relates to the technical field of photovoltaic cables, and provides an environmentally friendly multi-core photovoltaic cable, which includes a core body, an insulating layer and a flame-retardant layer. The insulating layer is arranged between the flame-retardant layer and the core body, and the insulating layer is made of methyl vinyl silicone rubber. It is made of the insulating material of the base material, and the outside of the flame-retardant layer is provided with a protective layer for rat ants, and the outer layer of the protective layer for rat ants is covered with an outer sheath layer; The anti-termite and rodent-proof agent are added to the material composition of the protective layer. Rodent ants will not dare to further bite the inner layer after biting the outer sheath layer. When burning, no toxic and harmful gases will be released, which can ensure safety. It can also reflect environmental protection.
Description
technical field [0001] The invention relates to the field of cable technology, in particular to an environment-friendly multi-core photovoltaic cable. 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. In addition to the rapid development of government-supported photovoltaic power plants, private investors are also actively building factories and plan to put them into production for global sales. of solar modules. Therefore, the market demand for photovoltaic cables, the key components used in solar energy technology, is huge, and the industrialization prospect is very broad. [0003] Since solar systems are often used under harsh environmental conditions (such as high temperature, ultraviolet radiation, ozone, severe temperature changes, and chemical attack, etc.), working under such conditions can make the cable jacket brittle, decompose the insula...
