Tension-resistant high-temperature resistant irradiation cross-linked polyolefin insulated photovoltaic cable

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.
