太阳能光伏电站常用的光伏电缆特性要求
2018-06-20 11:12
    太阳能光伏电站常用的光伏电缆时常暴露在阳光之下,产品会在恶劣环境条件下使用,如高温和紫外线辐射。目前,我们可采用的各种材料有PVC、橡胶、TPE材料,但技术上,橡胶电缆额定温度为90°C,PVC电缆额定温度为70°C,有许多EPC商为了节省成本,选择普通的PVC电缆来替代光伏电缆,这将大大影响系光伏电站的使用寿命。 如果电缆护套强度不够,则电缆绝缘层将会受到严重损坏,电缆使用过程中会出现短路、火灾和人员伤害危险等问题的出现。 光伏电缆的特性是由其电缆专用绝缘料和护套材料决定的,我们称之为交联PE,经过辐照加速器辐照以后,电缆料的分子结构会发生改变,从而全面提高产品性能。我公司拥有美国RDI公司进口“地拉米”电子加速器机组具有功率大、功能全、技术含量高、用途广等多种优点,被国内外专家誉为“世界一流中国第一照”。公司生产的PV1-F(镀锡无卤聚烯烃绝缘无卤聚烯烃扩大护套光伏电缆)通过了TUV认证。产品符合德国莱茵TUV 标准2PfG 1169/08.2007(技术规范)产品使用特性:1、电压等级AC 0.6/1kVDC 1.8kV最高允许工作电压(AC):0.7/1.2kV最高允许工作电压(DC):0.9/1.8kV2、试验电压AC:6.5kVDC: 15kV时间:5分钟3、温度范围环境温度-40℃到+120℃4、绝缘和护套采用交联聚烯烃材料5、电缆使用寿命不少于25年的要求。
   Photovoltaic cables commonly used in solar photovoltaic power stations are often exposed to sunlight, and products will be used in harsh environmental conditions, such as high temperature and ultraviolet radiation. At present, all kinds of materials we can use are PVC, rubber and TPE materials, but technically, the rated temperature of the rubber cable is 90 C and the rated temperature of the PVC cable is 70 C. There are many EPC merchants to choose ordinary PVC cable to replace the photovoltaic cable in order to save the cost. This will greatly affect the service life of the photovoltaic power station. If the strength of the cable sheath is not enough, the insulation layer of the cable will be seriously damaged, and the problems such as short circuit, fire and the danger of personnel damage will appear during the use of the cable. The characteristics of the photovoltaic cable are determined by the insulating material and sheath material of the cable. We call it the crosslinked PE. After irradiation, the molecular structure of the cable material will change, thus improving the performance of the product. Our company owns the RDI imported "Di rami" electronic accelerator unit with many advantages, such as large power, full function, high technical content, wide use and so on. It is praised by experts at home and abroad as "the first picture of the world class China". The PV1-F (tin free halogen free polyolefin insulated halogen-free polyolefin expanded sheathed photovoltaic cable) has been certified by TUV. The product meets the characteristics of TUV 2PfG 1169/08.2007 (technical specification) of Rhine, Germany: 1, voltage grade AC 0.6/1kVDC 1.8kV maximum allowable operating voltage (AC): 0.7/1.2kV maximum allowable operating voltage (DC): 0.9/1.8kV2, test voltage AC:6.5kVDC: 15kV time: 5 minutes 3, temperature range and environment temperature to 4, absolute The use of crosslinked polyolefin material 5 and cable life of not less than 25 years.
