Extra High Current Enclosed Busway

Qingdao Fenghua Electric Manufacturing Co., Ltd. manufactures premium Extra High Current Enclosed Busway. Distinguished from conventional 6300A and below busway, this extra high current model adopts multi-parallel stacked copper busbar structure to bear continuous ultra-large current. High-purity copper conductors go through precision polishing and silver plating to reduce contact resistance. High-temperature halogen-free flame-retardant insulating sheets are tightly laminated between phases. The reinforced non-magnetic alloy housing suppresses eddy current loss and improves mechanical rigidity to resist huge electromagnetic force during short-circuit faults. This product is mainly applied for the main incoming line of large-capacity transformers. It replaces numerous parallel large-section power cables, saving power room space and lowering joint failure risks. It can be made as feeder type without tap-off outlets for pure main trunk transmission, for new construction and expansion of mega power distribution systems.

Product Parameter (Specification)

Product Features and Application Scope

Extra High Current Enclosed Busway is engineered for mega low-voltage main feeders that require extremely large continuous power transmission.

Core Advantages

1. Multi-stack Conductor Design for Extra High Current Multi-layer stacked silver-plated copper bars achieve stable continuous operation under 6300A~8000A, with sufficient thermal margin for peak load impact.

2. Reinforced Non-magnetic Housing Non-magnetic alloy shell minimizes eddy current and hysteresis loss. High mechanical strength restrains busbar displacement under severe short-circuit electromagnetic shock.

3. Ultra-low Impedance & Low Power Loss Silver-plated high-purity copper reduces contact resistance, lowering line voltage drop and long-term operation energy consumption for mega projects.

4. Feeder-type Main Trunk Structure No tap-off outlets along the busway, eliminating insulation weak points, maximizing reliability for transformer main incoming feeders.

5. Compact Layout Saves Power Room Space Compared with dozens of parallel heavy cables, integrated busway greatly reduces occupied space and simplifies electrical arrangement in power house.

6. Full Range of Heavy-duty Modular Fittings Custom heavy elbows, tees, expansion joints, end closures and special transition terminals for large-capacity transformer connection.

Application Scenarios Hyper-scale IDC main incoming trunk, large metallurgical & smelting plant main power supply, hub substation 0.4kV main bus, mega chemical and energy base, large industrial park central power distribution.

Production Details and Craftsmanship

Qingdao Fenghua Electric adopts exclusive multi-stack lamination process for Extra High Current Enclosed Busway. Copper busbars are precision cut, polished and silver-plated. High-temperature halogen-free insulating sheets are laminated and compressed between stacked conductors. The reinforced non-magnetic housing is processed with anti-corrosion powder coating. Every bus segment undergoes insulation resistance test, power frequency withstand voltage test, continuous full-load temperature rise test and short-circuit simulation test before delivery. We accept third-party witness inspection and non-standard customized transition terminals for mega EPC projects.
