Photovoltaic cable tray is a universal wiring product that is suitable for efficient construction of modern new energy projects. It is characterized by lightweight, easy installation, and high adaptability, and meets the construction needs of decentralized construction, high-altitude operations, and large-span laying in photovoltaic projects. It is widely used in various civil, industrial, and overseas photovoltaic new energy engineering projects. On the basis of ensuring the standard structural strength and bearing capacity, the product optimizes its overall weight, making it more convenient for manual handling and high-altitude installation compared to traditional heavy-duty cable trays. It does not require the assistance of large lifting equipment, effectively reducing the construction difficulty and transportation costs of mountainous areas, roofs, and remote photovoltaic sites. The product adopts standardized modular design and is equipped with various universal accessories such as elbows, tees, and connectors. The hole positions are regular and the splicing is convenient. It can adapt to the complex pipeline routing and inclination laying requirements of photovoltaic projects, greatly improving on-site construction efficiency and shortening project construction cycles. At the same time, the product has good dust and moisture resistance, as well as deformation resistance. The cable layout is neat and orderly, making it easy for later power station inspections, line maintenance, and expansion and renovation. Suitable for laying various specifications of photovoltaic DC cables, compatible with various photovoltaic system wiring schemes, with outstanding cost-effectiveness, it is the preferred wiring matching solution for new energy photovoltaic infrastructure at home and abroad.
