1250A Air Insulated Busway

Qingdao Fenghua Electric Manufacturing Co., Ltd. specializes in the production of 1250A Air Insulated Busway, a mainstream heavy-current busbar product widely adopted in modern low-voltage power distribution systems. Compared with conventional 800A and 1000A busways, the 1250A model adopts upgraded conductor cross-section and optimized air convection structure, providing stronger load impact resistance and higher operation stability. With air as the main insulating medium, it maintains safe phase-to-phase clearance and excellent heat dissipation performance during long-term full-load operation. This busway is mainly used for main power incoming lines, workshop general power trunk and building main vertical power supply, effectively solving the overload and heating problems of conventional medium-current bus ducts in large-load scenarios. It is the preferred standard heavy-current trunking equipment for new construction, renovation and capacity expansion of medium and large-scale power distribution projects.

Product Parameter (Specification)

Product Features and Application Scope

The 1250A Air Insulated Busway is engineered for medium-to-large heavy-load power distribution scenarios. It upgrades conductor specifications and heat dissipation structure on the basis of conventional medium-current busways, featuring stronger overload resistance, more stable full-load operation and wider engineering adaptability, perfectly meeting the main power supply demands of large and medium-sized projects.

Core Advantages

1. Sufficient 1250A Full-load Operation Redundancy

Adopts upgraded thickened conductor structure with reasonable current density design. It maintains stable temperature rise and no abnormal heating under long-term 1250A rated full-load operation, effectively avoiding overload risks during peak power consumption.

2. Optimized Air Heat Dissipation Structure

Scientifically enlarged air insulation gap and streamlined convection channel accelerate hot air circulation inside the busway. The heat dissipation efficiency is significantly improved compared with smaller current busways, adapting to long-duration heavy-load working conditions.

3. Strong Short-circuit & Impact Resistance

Reinforced insulating supports and integral fixed structure greatly improve short-circuit withstand capacity. It can resist instantaneous current impact and electromagnetic force fluctuation to ensure system safety during grid faults.

4. High Matching for Large Engineering Main Trunk

1250A is the most widely used main incoming current grade for medium and large projects. It perfectly matches the power load of industrial parks, high-rise complexes and supporting power facilities with high engineering universality.

5. Stable Power Quality & Low Loss

High-precision polished conductors reduce overall impedance and contact resistance, effectively lowering power transmission loss and voltage drop, ensuring stable and high-quality power supply for heavy-load equipment.

6. Complete Engineering Customization & Matching

Qingdao Fenghua Electric supports customized length, special-angle elbows, tee joints, tap-off positions and protection grades to meet personalized layout requirements of large engineering projects.

Application Scenarios: Large industrial factory main power trunk, industrial park centralized power distribution, high-rise building main vertical power supply, shopping mall and hotel complex power distribution, substation low-voltage outlet connection, medium-sized data center main power supply, old project power expansion and upgrading.

Production Details and Craftsmanship

Qingdao Fenghua Electric strictly implements heavy-current production standards for 1250A Air Insulated Busway. The core conductors adopt integral precision cutting and surface anti-oxidation treatment to ensure uniform current conduction and stable load capacity. The internal insulating components are made of high-temperature resistant, flame-retardant and anti-aging materials, which firmly fix the phase spacing to avoid structural displacement under heavy current impact. The high-strength alloy shell is tightly assembled with excellent dustproof and moistureproof performance. Each finished bus section passes strict full-load temperature rise test, insulation withstand voltage test and short-circuit simulation test before delivery. The factory supports third-party inspection, batch bulk procurement and phased delivery for large-scale engineering projects.
