5000A Sandwich Busway

Qingdao Fenghua Electric Manufacturing Co., Ltd. professionally produces premium 5000A Sandwich Busway, the ultimate flagship model of low-voltage compact bus trunking. Different from 3200A / 4000A high-current busways, the 5000A version adopts multi-stack super-thick high-purity copper busbars and upgraded integrated lamination technology, breaking the maximum load limit of conventional compact bus ducts. The phase conductors are tightly clamped with multi-layer high-temperature, halogen-free, low-smoke flame-retardant insulating materials, forming an ultra-rigid integrated structure that completely restrains conductor displacement under extreme short-circuit electromagnetic impact. The thickened reinforced alloy housing provides superior mechanical strength and environmental protection performance. This busway thoroughly solves the bottlenecks of insufficient load margin, excessive temperature rise and weak fault resistance in ultra-large-capacity power distribution. It perfectly replaces numerous parallel heavy-duty power cables, greatly simplifying the layout of super-large power distribution rooms and eliminating massive cable joint hidden dangers. It is the exclusive preferred power trunking equipment for new construction, capacity expansion and electrical upgrading of various world-class mega engineering projects.

Product Parameter (Specification)

Product Features and Application Scope

5000A Sandwich Busway is custom-developed for ultra-limit heavy-load power distribution scenarios, focusing on extreme full-load stability, ultimate fault resistance and system energy saving, meeting the strictest power supply requirements of top-level mega projects.

Core Advantages

1. Ultimate 5000A Full-load Continuous Operation

Adopts multi-stack super-large cross-section copper conductor structure with ultra-low current density design. It maintains extremely stable and low temperature rise under long-term 24/7 5000A full-load operation, possessing massive load margin to resist extreme peak impact and equipment startup surge, ensuring zero overheating failure of the core power trunk.

2. Industry-top Short-circuit Dynamic & Thermal Stability

Ultra-dense multi-layer lamination integral locking structure firmly fixes all phase conductors as a whole. It can withstand the maximum instantaneous electromagnetic force and thermal shock of low-voltage system short-circuit faults, completely avoiding conductor deformation, displacement and burnout, maximizing the safety of ultra-large-capacity power systems.

3. Ultra-low Impedance & Significant Energy Saving

Premium silver-plated super-thick copper bars minimize contact resistance and line impedance to the greatest extent, effectively reducing power transmission loss and voltage drop. It guarantees ultra-stable power quality for high-end precision equipment and heavy-load units, bringing long-term energy-saving benefits for mega projects.

4. Integrated Compact Structure Saves Super Project Space

Compared with the traditional solution of multiple parallel large-section cables for 5000A ultra-large current transmission, the integrated sandwich busway has a highly compact body, which greatly saves power room and shaft space, simplifies complex electromechanical layout, and reduces later operation and maintenance costs.

5. Extreme Environmental Adaptability & Anti-aging Performance

All insulating materials adopt ultra-high temperature resistant, anti-aging and flame-retardant raw materials exclusive for heavy current. The thickened anti-corrosion shell adapts to harsh industrial environments and long-term uninterrupted operation, with ultra-long service life and ultra-low failure rate.

6. Exclusive Customization for Top-tier Mega Projects

Provides one-to-one exclusive customized solutions, including ultra-heavy large-current transition terminals, special-shaped elbows, reinforced supporting hangers and real-time temperature monitoring modules, fully matching the complex design requirements of super-large key projects.

Application Scenarios: Hyperscale data center cluster core incoming trunk, super-large chemical/metallurgical/energy heavy industrial base main power supply, hub substation low-voltage total incoming line, national key infrastructure mega power project, ultra-large industrial park power comprehensive upgrading project.

Production Details and Craftsmanship

Qingdao Fenghua Electric adopts ultra-heavy current exclusive super process for 5000A Sandwich Busway. The core copper conductors are integrally precision cut, multi-level polished and premium silver-plated to ensure uniform conduction and minimal contact loss. Multi-layer composite high-density halogen-free flame-retardant insulating sheets are stacked and pressed between phases to form a seamless and high-strength insulating layer. The whole body is clamped and assembled integrally, equipped with thickened high-rigidity alloy shell and heavy anti-corrosion electrostatic spraying treatment. Each finished bus segment undergoes strict 5000A full-load continuous temperature rise test, extreme short-circuit simulation test, insulation withstand voltage and long-term aging test before leaving the factory. The factory fully supports third-party authoritative witness inspection, non-standard super-large current customization and stable bulk supply for national key projects and super EPC projects.
