2500A Air Insulated Busway

Qingdao Fenghua Electric Manufacturing Co., Ltd. launches professional 2500A Air Insulated Busway, an ultra-large current power transmission equipment positioned for high-load core power supply scenarios. Different from conventional 1600A and below medium and large current busways, the 2500A model adopts fully upgraded super thickened high-purity conductors and enhanced reinforced air insulation structure. It breaks the load limit of ordinary bus ducts, effectively solving common problems such as insufficient load margin, excessive temperature rise and weak impact resistance of large current busways in super large projects. With optimized large-space air convection heat dissipation system and high-rigidity anti-deformation structure, it can operate stably under 24-hour continuous full-load and frequent peak impact conditions. It is the exclusive preferred trunking equipment for super industrial projects, large IDC clusters, municipal power distribution centers and ultra-high-rise building main power supply systems.

Product Parameter (Specification)

Product Features and Application Scope

The 2500A Air Insulated Busway is professionally developed for super heavy-load core power distribution scenarios. It focuses on ultra-large current carrying capacity, extreme temperature rise control and super strong short-circuit stability, completely solving the technical pain points of insufficient load capacity and poor stability of conventional busways in large-scale key projects.

Core Advantages

1. Ultra-large Load Margin for 2500A Full-load Operation

Adopts super thickened conductor design with scientific low current density configuration. It maintains ultra-low temperature rise under long-term 2500A full-load continuous operation, with sufficient margin to cope with equipment startup impact and seasonal peak power surge, ensuring zero overheating failure of core power trunk.

2. Super High Short-circuit Dynamic & Thermal Stability

Equipped with customized heavy-duty insulating supports and integral reinforced rigid structure. It can resist extreme electromagnetic impact and instantaneous thermal shock during short-circuit faults, effectively preventing busbar deformation, displacement and burnout, and protecting the safety of the entire large-capacity power distribution system.

3. Large-space Air Convection Heat Dissipation

The optimized oversized air insulation gap forms an unobstructed three-dimensional heat dissipation channel. Compared with medium current busways, the heat dissipation efficiency is greatly improved, which can quickly export cumulative heat under ultra-large current and ensure long-term stable operation of the equipment.

4. Ultra-low Power Loss & Stable Power Quality

Super-large cross-section conductors effectively reduce overall impedance and contact resistance, significantly lowering power transmission loss and voltage drop. It ensures high-precision stable power supply for high-precision equipment and core load groups in key projects.

5. Integrated Anti-loosening & Anti-vibration Structure

All connecting parts adopt heavy-duty anti-loosening locking technology, which can resist long-term vibration of large-scale power equipment and avoid poor contact of bus joints. It is especially suitable for continuous operation of heavy industrial environments.

6. Exclusive Customization for Large Key Projects

Qingdao Fenghua Electric provides exclusive customized solutions for 2500A super large current busways, including special terminal transition joints, ultra-large current tap-off boxes, special bending and elevation accessories, to meet the complex layout requirements of large-scale hub power distribution projects.

Application Scenarios: Super-large industrial manufacturing base main power trunk, data center cluster core power supply, municipal power distribution hub equipment connection, ultra-high-rise building main vertical power supply, large substation low-voltage main incoming line, large commercial complex central power distribution system, key engineering power upgrading and expansion projects.

Production Details and Craftsmanship

Qingdao Fenghua Electric implements ultra-heavy current exclusive production process for 2500A Air Insulated Busway. The core conductors are formed by integral precision cutting and multi-layer polishing treatment, with smooth surface and uniform conductivity, ensuring no local heat concentration under ultra-large current. The internal insulating components are made of high-strength anti-aging flame-retardant special materials for heavy current, which can maintain stable supporting and insulating performance under long-term high temperature and strong electromagnetic environment. The overall shell adopts thickened high-rigidity alloy plate with anti-corrosion and wear-resistant treatment. Each finished bus section must pass strict 2500A full-load temperature rise test, extreme short-circuit simulation test and long-term aging test before delivery. The factory supports exclusive matching supply for national key projects, EPC general contracting projects and large-scale bulk procurement.
