Abstract

The invention discloses a tension-resistant high-temperature resistant irradiation cross-linked polyolefin insulated photovoltaic cable, comprising a copper conductor, a tension-resistant element, a high-temperature resistant structure layer, a low-smoke halogen-free irradiation cross-linked flame-retardant polyolefin insulation layer, a low-smoke halogen-free high-temperature resistant insulation layer and a low-smoke halogen-free irradiation cross-linked flame-retardant polyolefin sheath layer, wherein the copper conductor is closely stranded with the tension-resistant element to form a stranding body, the high-temperature resistant structure layer is covered on the stranding body, the low-smoke halogen-free irradiation cross-linked flame-retardant polyolefin insulation layer is covered on the high-temperature resistant structure layer, the low-smoke halogen-free high-temperature resistant insulation layer is covered on the low-smoke halogen-free irradiation cross-linked flame-retardant polyolefin insulation layer, the low-smoke halogen-free irradiation cross-linked flame-retardant polyolefin sheath layer is extruded on the low-smoke halogen-free high-temperature insulation layer. The operation temperature of the cable is relatively wide, namely the temporary overload of the conductor achieves +130 DEG C, the operation environment temperature is in the range between -40 DEG C and +110 DEG C (TUV upper limit is +90DEG C), simultaneously the cable has the capability that the high-temperature resistant short-period temperature exceeds 130 DEG C environment requirement. The tension-resistant high-temperature resistant irradiation cross-linked polyolefin insulated photovoltaic cable has good features of resistance to ozone, ultraviolet, water vapor and flame retardant property.

Description

technical field [0001] The invention relates to the technical field of power cables, in particular to a tension-resistant and high-temperature radiation-resistant cross-linked polyolefin insulated photovoltaic cable, which is used for wiring systems connecting solar panels, storage batteries or other power collecting units such as photovoltaic modules and inverters. Background technique [0002] The solar photovoltaic grid-connected power generation industry with the advantages of zero emissions, long life, and inexhaustible resources has gradually become one of the most concerned emerging industries in the world today. Solar photovoltaic cables are used to connect solar panels, batteries or other power collecting units such as photovoltaic modules and inverters in the wiring system. [0003] The solar system is used in a harsh environment, and photovoltaic cables should have excellent unique properties. [0004] Solar technology will be one of the future green energy techn...
