4000A High Density Copper Enclosed Busway

Qingdao Fenghua Electric Manufacturing Co., Ltd. manufactures premium 4000A High Density Copper Enclosed Busway. This high-density copper enclosed busway adopts compact laminated stacking design for high-purity copper busbars, which increases current density while keeping the housing footprint smaller than conventional busway. High-purity copper conductors are precision machined and tin or silver plated to reduce contact resistance. High-temperature halogen-free flame-retardant insulation sheets are tightly compressed between phase conductors. The rigid non-magnetic alloy housing suppresses eddy current loss and provides strong mechanical strength to resist huge electromagnetic force during short-circuit faults. It can be designed as feeder type or plug-in type according to project requirements. This busway replaces multiple parallel large-section power cables, tidies power room layout and reduces hidden risks of cable joint failure, suitable for new construction, renovation and capacity expansion of heavy-load power distribution systems.

Product Features and Application Scope

4000A High Density Copper Enclosed Busway is engineered for projects requiring 4000A continuous power transmission with limited installation space.

Core Advantages

1. High Density Stacked Copper Design Optimized compact laminated copper arrangement realizes 4000A rated current in smaller housing size, saving precious space in power distribution rooms.

2. Low Impedance & Low Voltage Drop Plated high-purity copper bars minimize contact resistance, reducing line loss and voltage drop during long-hour heavy-load operation.

3. Superior Short-circuit Performance Tight laminated assembly locks conductors firmly. The rigid non-magnetic housing withstands strong electromagnetic impact in short-circuit events and prevents copper bar deformation.

4. Flexible Structural Options Available in feeder type (no tap outlets) or plug-in type with matching tap-off boxes, satisfying both main trunk transmission and branch power tapping demands.

5. Reliable Environmental Adaptability Fully enclosed housing with powder coating provides dust and moisture protection, suitable for indoor power houses and building vertical shafts.

6. Complete Modular Accessories Custom straight segments, 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 4000A High Density Copper Enclosed Busway. Copper busbars are precision cut, polished and surface tin-plated or silver-plated. 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, 4000A continuous temperature rise test and short-circuit simulation test before shipment. We accept third-party witness inspection and non-standard customized terminals for EPC projects.
