报告摘要

单芯光伏电缆施工放线速度慢，需要标识、捆扎、长度无法保持一致，双芯电缆具有易布线、长度一致、无需捆扎等特点。常规光伏电缆结构简单，无法直埋，添加阻燃剂后防水性能减弱，无法对鼠蚁进行有效的防护，需要通过穿管和桥架进行保护。新型铠装可分离光伏电缆具有可直埋、优良的防水性能，铠装结构可以有效的防鼠蚁、防昆虫，提高耐腐蚀性。采用逆变器后移的敷设方式可以节省初始投资成本。

Abstract

The construction and laying speed of single core photovoltaic cables is slow, requiring identification, bundling, and inconsistent length. Dual core cables have the characteristics of easy wiring, consistent length, and no need for bundling. Conventional photovoltaic cables have a simple structure and cannot be directly buried. Adding flame retardants weakens their waterproof performance and cannot effectively protect against rodents and ants. Therefore, they need to be protected through conduit and cable trays. The new type of armored detachable photovoltaic cable has direct burial and excellent waterproof performance. The armored structure can effectively prevent rodents, ants, insects, and improve corrosion resistance. The installation method of using inverters to move backwards can save initial investment costs.
