Sandwich Busway for Power System

Qingdao Fenghua Electric Manufacturing Co., Ltd. manufactures premium Sandwich Busway dedicated for power system application. Unlike busway for commercial buildings or data centers, this version is engineered to withstand severe short-circuit impact and continuous heavy load fluctuation in power station and substation environments. High-purity copper or aluminum conductors are laminated with high-temperature halogen-free solid insulation sheets. The compact sandwich clamping structure locks busbars firmly to resist massive electromagnetic force during fault conditions. Fully enclosed rigid metal housing provides reliable protection against dust, humidity and slight vibration commonly seen in power houses. It can replace multiple parallel power cables, simplify substation layout and reduce hidden risks of cable joint failure. It is widely adopted for new construction, reconstruction and capacity expansion of thermal power plants, hydropower stations, wind power booster stations and urban substations.

Product Features and Application Scope

Sandwich Busway for Power System is developed for mission-critical power grid and power station scenarios, prioritizing fault resistance, operational stability and long service life.

Core Advantages

1. Superior Short-circuit Dynamic & Thermal Stability Tight laminated clamping structure firmly restrains busbars, resisting huge electromagnetic force during short-circuit faults and preventing permanent deformation of conductors.

2. Excellent Anti-vibration Performance Optimized mechanical structure adapts to vibration from power plant equipment, avoiding loose connection and abnormal temperature rise under long-term operation.

3. Stable Performance Under Load Fluctuation Low impedance design controls temperature rise effectively even with frequent load changes, meeting the working characteristics of power system auxiliary power supply.

4. Strong Environmental Adaptability Heavy-duty alloy housing with anti-corrosion coating, resistant to dust, moisture and weak corrosive gas inside power houses and substations.

5. Modular Heavy-duty Fittings Complete series of elbows, tees, expansion joints, end closures and transition joints, convenient for connection with transformers and LV switchgear cabinets.

6. Low Maintenance & Long Service Life High-quality insulation and plated conductors reduce aging risk. Joint inspection can be done via infrared thermal scanning without frequent shutdown.

Application Scenarios Power plant auxiliary power main trunk, substation 0.4kV LV interconnection, wind and solar booster station low-voltage distribution, grid power station renovation and capacity expansion, industrial power supply hub.

Production Details and Craftsmanship

Qingdao Fenghua Electric adopts power-system-grade lamination process for Sandwich Busway for Power System. Conductors are precision cut and surface tin-plated or silver-plated. High-temperature halogen-free insulating sheets are sandwiched between phases. The whole laminated assembly is clamped tightly and enclosed in thickened alloy housing with anti-corrosion coating. Each bus segment undergoes insulation resistance test, power frequency withstand voltage test, temperature rise test and short-circuit simulation test before delivery. We accept third-party witness type test and non-standard customized transition terminals to match power equipment.
