Abstract

The invention relates to a cable material for a photovoltaic cable, in particular to an irradiation crosslinking type low-smoke halogen-free flame-retardant polyolefin cable material for a photovoltaic cable. The polyolefin cable material comprises polyolefin resin, a main flame retardant agent, a flame retardant synergistic agent, an antioxidant, a surface treatment agent, a lubricating agent and other auxiliary agents. The invention fine selects a high-quality polyolefin resin complex system and adopts a flame retardant agent complex synergistic action system so that the material has optimal flame-retardant performance and ultraviolet aging resistance and plays a complete protection role in the cable.

Description

Technical field: [0001] The invention relates to a cable material for photovoltaic cables, in particular to a radiation cross-linked low-smoke, halogen-free, flame-retardant polyolefin cable material for photovoltaic cables. Background technique: [0002] Irradiation cross-linked low-smoke halogen-free flame-retardant polyolefin cable material for photovoltaic cables is a material that does not contain halogens, has low smoke generation, and is resistant to ultraviolet light. It is a new solar energy, clean energy, and increases the total energy supply. Maintain the stability of energy supply in unexpected situations. Solar energy is absorbed by concentrators of different sizes and then passed through a set of series-connected energy storage batteries to convert solar energy into electrical energy and then output it to the end user. The photovoltaic cable needs to be connected between the device and the storage battery. Since the photovoltaic cable is exposed to sunlight fo...
