Publish Time: 2025-06-25
In modern power engineering, the composite shielded insulated tubular busbar body is widely used in high-rise buildings, data centers, industrial plants, substations and other high-current power transmission and distribution systems with its excellent conductivity, safety protection capability, compact structure and convenient installation and maintenance. As an upgraded alternative to traditional cables and rectangular busbars, it not only improves the stability and safety of power transmission, but also shows significant advantages in space utilization, energy saving and environmental protection.The biggest advantage of the composite shielded insulated tubular busbar body lies in its excellent current carrying capacity and heat dissipation performance. High-purity copper or aluminum alloy is used as the conductor material, and it is wrapped with a multi-layer composite insulation structure, so that the busbar has a higher current carrying capacity and lower temperature rise. Compared with traditional cables, it can carry more current per unit cross-sectional area, which is suitable for high-power and high-density power consumption scenarios, such as data center UPS power supply system, factory production line distribution cabinet, etc., effectively improving energy utilization efficiency.In terms of safety, the composite shielded insulated tubular busbar body performs well. The metal shielding layer on the outside of the trough body can effectively suppress electromagnetic interference, prevent leakage current, and ensure that the equipment runs more stably and reliably. At the same time, the overall structure has good fire, moisture and corrosion resistance, and can operate stably for a long time even in high temperature, humid or dusty environments, greatly reducing the safety hazards caused by line aging or short circuits, and ensuring the safety of personnel and equipment.In terms of structural design, the composite shielded insulated tubular busbar body is highly integrated and modular, which is convenient for on-site installation and later expansion. Its round tube structure not only takes up less space, but also has stronger mechanical strength, strong bending and compression resistance, and is suitable for complex wiring environments. The standardized interface design makes the installation process faster and more efficient, reduces the construction period and labor costs, and is especially suitable for large-scale engineering projects and renovation and upgrading projects.Environmental protection and energy saving are also one of its important competitive advantages. Due to low conductor loss and good heat dissipation effect, the energy consumption of the bus duct during operation is significantly lower than that of the traditional cable system, which helps enterprises achieve energy conservation and emission reduction goals. In addition, the product has a long service life and low maintenance frequency, which further reduces the operating cost throughout the life cycle, in line with the industry trend of green buildings and sustainable development.In addition, the composite shielded insulated tubular busbar body has wide applicability and flexible configuration capabilities. Different specifications and functional modules can be customized according to different voltage levels, current capacities, and installation environments to meet the application requirements of various voltage systems from 400V to 35kV. Whether it is vertical shaft wiring, horizontal distribution trunks, or connecting transformers and switch cabinets, it can provide stable and efficient power transmission solutions.The composite shielded insulated tubular busbar body is becoming an indispensable and important part of the modern power system with its high current carrying capacity, excellent heat dissipation performance, strong safety, modular structure, energy saving and environmental protection, and wide adaptability. It not only improves the reliability and efficiency of power transmission, but also provides solid support for building an intelligent and green power supply and distribution system.
