Core Advantages

1. High Conductivity, Low Loss: Energy-Efficient and High-Performance

T2-grade electrolytic copper conductors exhibit a resistivity of ≤0.01777 Ω·mm²/m at 20°C and a conductivity exceeding 98%—far surpassing that of ordinary copper materials. This characteristic significantly reduces energy loss during power transmission; over the long term, it enables enterprises to realize substantial savings on electricity costs. Furthermore, the surface of the copper conductors can be optionally treated with tin or silver plating to effectively enhance resistance to oxidation and corrosion, lower contact resistance, extend the service life of connection points, and reduce future maintenance expenditures.

2. Compact Structure: Optimized Space Utilization

The unique "sandwich" design—featuring tightly stacked phase conductors—compresses the electrical clearance between conductors to a mere 6–10 mm, thereby completely eliminating air gaps between phases. Compared to traditional busbar trunking systems, this design reduces overall volume by over 30% while maintaining equivalent current-carrying capacity. This allows for flexible installation in space-constrained environments—such as electrical risers and equipment-dense workshops—significantly enhancing space utilization efficiency and creating greater possibilities for building layouts and equipment arrangements.

3. Efficient Heat Dissipation: Stable Operation

Copper conductors possess excellent thermal conductivity, allowing heat to be rapidly transferred through the insulation layer to the metal casing. The casing is constructed from an aluminum-magnesium alloy and features an integrated heat-dissipation fin design; this increases the surface area by over 30% compared to standard casings, enabling highly efficient heat dissipation through a dual mechanism of convection and radiation. During operation at rated current, the temperature rise at connection terminals remains ≤60K, while the casing temperature rise remains ≤30K. This ensures stable operating temperatures for the busbar trunking system over the long term, effectively preventing insulation aging and performance degradation caused by overheating, and thereby guaranteeing the reliability of the power distribution system.

4. Comprehensive Protection: Adaptable to Complex Environments

The fully enclosed metal casing undergoes surface treatments—such as anodizing, electrophoresis, or fire-retardant coating—to provide multi-level protection ranging from IP54 to IP68. Standard models offer dust and splash protection, meeting the operational requirements of typical industrial plants and commercial buildings. Waterproof models provide protection against short-term or even continuous immersion, making them suitable for humid environments such as underground utility tunnels and water treatment plants. Fire-resistant models are capable of maintaining power supply for over 180 minutes at extreme temperatures of 960°C, providing a reliable safeguard for fire safety circuits and emergency power supply systems. Furthermore, the "sandwich" structure lacks continuous air channels, thereby fundamentally eliminating the "chimney effect" during a fire and enhancing the system's fire safety performance.

5. Modular Design for Convenient Installation

The busway system utilizes factory-prefabricated, standard modular units. During on-site installation, these units are rapidly connected using double-ended torque-controlled bolts and disc springs. This design accommodates installation tolerances of ±4 mm, significantly reducing construction complexity and time costs. Plug-in units can be inserted into or removed from the busway at any location while the system remains energized; the "first-to-connect, last-to-disconnect" grounding design ensures operational safety. Moreover, the system supports a minimum of 200 plug-in/plug-out cycles, allowing for flexible adaptation to requirements such as production line adjustments and equipment expansion, while facilitating easier maintenance and modification in the future.

Application Scenarios

1. Industrial Manufacturing Sector

In the production workshops of industries such as automotive manufacturing, mechanical processing, metallurgy, and chemicals, copper-conductor sandwich-type busduct systems provide a stable main power backbone for high-power equipment—including large motors, welding machinery, and automated production lines. Their high current-carrying capacity is capable of handling the heavy-load conditions associated with the frequent starting and stopping of machinery, while their modular plug-in design facilitates production line adjustments and the addition of new equipment, thereby helping enterprises achieve highly efficient production.

2. Data Centers and Healthcare Facilities

Server clusters in data centers and large-scale medical equipment in hospitals demand exceptionally high levels of continuity and stability in their power supply. The low-loss characteristics of this busduct system minimize energy waste during power transmission. Furthermore, intelligent product variants can integrate temperature and current monitoring modules, enabling remote operation and maintenance via RS485 or wireless transmission; this allows for real-time monitoring of equipment status, providing reliable power assurance for critical loads.

3. High-Rise Building Power Distribution

Within the electrical distribution risers of high-rise buildings, copper-conductor sandwich-type busducts are installed vertically to serve as the main power supply lines for each floor. Their compact structure conserves valuable shaft space, while their efficient heat dissipation design ensures stability during long-distance vertical power transmission, providing a balanced and reliable power supply to every floor of office buildings, hotels, residential complexes, and similar structures.

4. Special Environmental Conditions

For special environments characterized by high humidity, corrosiveness, or dust—such as underground utility tunnels, rail transit systems, and coastal facilities—waterproof and corrosion-resistant busduct variants are available. Resin-cast busducts, featuring an IP68 protection rating, are constructed without a metal casing and are completely sealed; this design ensures long-term, stable operation in harsh environments, effectively preventing equipment failures caused by adverse environmental factors.
