3200A Sandwich Busway

Qingdao Fenghua Electric Manufacturing Co., Ltd. professionally produces 3200A Sandwich Busway, a top-tier high-current compact bus duct for heavy-duty power distribution. Compared with 2500A and lower current sandwich busways, the 3200A version adopts enlarged cross-section conductors and optimized dense lamination technology, solving the load margin shortage and temperature rise bottleneck of medium-current busways in super large-load scenarios. The high-purity copper conductors are tightly clamped with high-temperature halogen-free flame-retardant insulating layers to form an integrated compact structure, which effectively resists extreme electromagnetic impact during short-circuit faults and avoids conductor displacement or deformation. The fully enclosed rigid alloy housing realizes dust-proof, moisture-proof and anti-corrosion protection, adapting to long-term 24/7 uninterrupted heavy-load operation. Replacing multiple parallel heavy cables, it simplifies power room and shaft layout, reduces joint failure risks, and is the preferred main trunk equipment for new construction, renovation and capacity expansion of various mega power distribution projects.

Product Parameter (Specification)

Product Features and Application Scope

3200A Sandwich Busway is engineered exclusively for ultra-heavy load core power distribution scenarios, focusing on full-load long-term stability, extreme fault resistance and space-saving layout, filling the performance gap of medium-current busways in super large-scale projects.

Core Advantages

1. Sufficient 3200A Full-load Operation Margin

Adopts super thickened conductor cross-section with scientific low current density design. It maintains ultra-low and stable temperature rise under long-term 3200A continuous full-load operation, with sufficient margin to cope with equipment startup impact and seasonal power peak surges, eliminating overheating risks of core power trunk.

2. Extreme Short-circuit Dynamic & Thermal Stability

High-density integrated lamination structure tightly locks all phase conductors. It can withstand huge instantaneous electromagnetic force and thermal impact during severe short-circuit faults, effectively preventing busbar deformation, displacement and burnout, ensuring overall power system safety.

3. Ultra-low Impedance & Energy Saving

High-precision polished and plated copper conductors minimize contact resistance and overall impedance, greatly reducing power transmission loss and voltage drop. It ensures stable high-quality power supply for core heavy-load equipment and improves system energy efficiency.

4. Compact Structure for Super Project Layout

Compared with multi-parallel cable solutions for 3200A large current, the integrated sandwich structure occupies far less shaft and power room space, simplifies electromechanical layout, and reduces later maintenance costs.

5. 24/7 Uninterrupted Operation Reliability

Adopts anti-aging, high-temperature resistant and flame-retardant insulating materials, adapting to round-the-clock continuous operation of key projects such as data centers and power stations, with ultra-low failure rate.

6. Customized Heavy-duty Matching Solution

Supports customized heavy transition terminals, large-current tap-off boxes and special-shaped pipe fittings, perfectly matching large-capacity transformers and main switchgear equipment for super projects.

Application Scenarios: Hyperscale data center cluster main incoming trunk, mega chemical/metallurgical heavy industrial base core power supply, large substation low-voltage main line, super high-rise commercial complex central power distribution, national key infrastructure power upgrading and expansion projects.

Production Details and Craftsmanship

Qingdao Fenghua Electric adopts exclusive ultra-heavy current manufacturing process for 3200A Sandwich Busway. The core copper conductors are integrally precision cut and multi-layer polished, with surface tin-plating or silver-plating treatment to ensure uniform conduction and low contact resistance. High-grade halogen-free low-smoke flame-retardant insulating sheets are tightly laminated between phases to form a seamless insulation structure. The thickened high-rigidity alloy shell undergoes heavy anti-corrosion and wear-resistant treatment, adapting to complex industrial and power environment. Each finished bus segment passes strict 3200A full-load temperature rise test, short-circuit simulation test, insulation resistance and withstand voltage test before delivery. The factory supports third-party witness inspection, non-standard customized components and bulk stable supply for large key projects.
