Qingdao Fenghua Electric supplies High Density Enclosed Busway, compact laminated enclosed bus duct optimized for high current carrying capacity within minimized overall dimensions. It adopts tightly stacked conductors with high-performance halogen-free laminated insulation, featuring compact footprint, low impedance, stable temperature rise and excellent short-circuit dynamic & thermal withstand performance. Rated current ranges from 250A up to 6300A, protection grade IP54 (IP65 optional). It is widely used in hyperscale data centers, heavy industrial plants, large commercial complexes and substation low-voltage main incoming systems. We provide custom straight segments, elbows, tees, expansion joints, transition terminals and third-party witness type tests, delivering space-saving high-current power backbone solutions for global EPC projects.
Qingdao Fenghua Electric Manufacturing Co., Ltd. manufactures premium High Density Enclosed Busway. This high-density busway adopts optimized laminated stacking structure, arranging conductors closely to maximize current carrying capacity while reducing housing width and height compared with conventional busway. Conductors can be high-purity copper (tin/silver plated) or 6101-T6 high conductivity aluminum alloy upon request. High-temperature halogen-free flame-retardant insulation sheets are tightly compressed between phases. Rigid non-magnetic alloy housing suppresses eddy current loss and provides strong mechanical rigidity to resist huge electromagnetic force during short-circuit faults. It can be designed as feeder type or plug-in type according to project layout. It replaces multiple parallel large-section power cables, optimizes power room layout and reduces risks of cable joint failure, suitable for new construction, renovation and capacity expansion of heavy-load power distribution systems with limited installation space.
Horizontal mounting in power room / vertical shaft mounting
Core Characteristic
Compact dimension, high current density, low impedance, controlled temperature rise, strong short-circuit resistance
Applicable Environment
Hyperscale data center, heavy industry, large commercial complex, substation LV main incoming
Execution Standard
GB/T 7251.6, IEC 61439-6
Product Features and Application Scope
High Density Enclosed Busway is engineered for heavy-load power distribution projects with constrained installation space.
Core Advantages
1. Compact High-density Laminated Structure Optimized stacking design delivers high rated current with smaller housing size, saving valuable space in power rooms and vertical shafts.
2. Flexible Conductor Selection Customers may select copper conductors for ultra-low impedance and high stability, or aluminum conductors for cost optimization.
3. Superior Short-circuit Mechanical & Thermal Performance Tight lamination locks conductors as a rigid assembly. The non-magnetic housing withstands strong electromagnetic impact during short-circuit events and prevents busbar deformation.
4. Low Impedance & Reduced Voltage Drop Plated copper or surface-treated aluminum minimizes contact resistance, cutting line loss and voltage drop under continuous heavy load.
5. Dual Structural Options Available as feeder type without tap outlets or plug-in type with matched tap-off boxes, covering both main trunk transmission and branch tapping requirements.
6. Complete Modular Accessories Custom straight sections, elbows, tees, expansion joints, end closures and heavy transition terminals for transformer and LV switchgear connection.
Application Scenarios Large data center main incoming trunk, heavy manufacturing plant main power feeder, super high-rise commercial building vertical power supply, substation 0.4kV main bus, large industrial park central distribution.
Production Details and Craftsmanship
Qingdao Fenghua Electric adopts dedicated high-density lamination process for High Density Enclosed Busway. Busbars are precision cut, polished and surface treated. High-temperature halogen-free insulating sheets are laminated and compressed between stacked conductors. The non-magnetic alloy housing is treated with anti-corrosion electrostatic powder coating. Every bus segment undergoes insulation resistance test, power frequency withstand voltage test, temperature rise test and short-circuit simulation test before shipment. We accept third-party witness inspection and non-standard customized terminals for EPC projects.
