3200A Air Insulated Busway

Qingdao Fenghua Electric Manufacturing Co., Ltd. produces premium 3200A Air Insulated Busway, the top-tier large-current air-type bus duct for mission-critical power distribution. Compared with 2500A and lower rating busways, the 3200A model upgrades conductor dimension, phase spacing and structural reinforcement to handle continuous ultra-heavy load and peak surge. It relies on air as the primary insulating medium, secured by high-strength flame-retardant supporting blocks to maintain consistent safe air clearance. The optimized air convection channel minimizes heat accumulation during round-the-clock full-load operation. It replaces multiple parallel heavy power cables, reducing joint failure risks and simplifying power room layout. This busway is the preferred main incoming trunk for new construction, capacity expansion and electrical retrofitting of large-scale key power projects requiring 3200A rated current.

Product Parameter (Specification)

Product Features and Application Scope

The 3200A Air Insulated Busway is engineered for mission-critical main incoming feeders. It focuses on extreme dynamic & thermal stability, low power loss and robust mechanical rigidity, solving bottlenecks of multi-cable parallel layout and joint overheating for mega-capacity power systems.

Core Advantages

1. Stable Continuous 3200A Full-load Operation Extra-large cross-section conductors adopt optimized low current density design, keeping temperature rise strictly within standard limits under long-term 3200A rated load, reserving sufficient margin for equipment startup impulse and seasonal power peak.

2. Superior Short-circuit Dynamic & Thermal Resistance Heavy reinforced support structure and rigid thick alloy housing can withstand massive electromagnetic force and instantaneous thermal energy generated during short-circuit faults, preventing busbar displacement, deformation and burnout of the whole trunk system.

3. Optimized Large-volume Air Convection Heat Dissipation Enlarged phase air gap forms smooth three-dimensional heat flow channel. Heat can dissipate rapidly through natural air circulation, convenient for routine infrared thermal inspection and predictive maintenance.

4. Low Impedance & Minimum Voltage Drop High-precision polished, tin/silver plated conductors reduce contact resistance and overall impedance, cutting power transmission loss and voltage drop, guaranteeing stable power quality for high-precision core loads.

5. Modular Heavy-duty System & Complete Accessories Available with heavy elbows, tees, expansion joints, end caps and large-current tap-off boxes. Modular assembly enables flexible layout for complex power room routing.

6. Customized Transition Terminals for Transformer & Switchgear Qingdao Fenghua Electric can design customized terminal connection plates to perfectly match low voltage terminals of large transformers and main inlet cabinets of switchgear, simplifying on-site installation.

Application Scenarios Hyperscale data center cluster main incoming trunk, mega industrial manufacturing base core power supply, large substation low voltage interconnection, municipal power distribution hub, super large commercial complex central power distribution, key national infrastructure power upgrading and expansion projects.

Production Details and Craftsmanship

Qingdao Fenghua Electric adopts flagship heavy-current manufacturing process for 3200A Air Insulated Busway. Conductors are precision cut, surface tin-plated or silver-plated to minimize contact resistance. High-temperature halogen-free flame retardant heavy-duty spacers firmly lock phase spacing against strong electromagnetic impact. Thickened high-rigidity alloy housing is treated with anti-corrosion coating for long service life. Every finished bus segment must pass insulation resistance test, power frequency withstand voltage test, full-load temperature rise test and short-circuit simulation test before shipment. We accept third-party witness inspection, non-standard prefabricated components and bulk supply for large EPC contractors.
