Product Features
1 Split winding design
● Triple split structure: Combining axial and radial split technology (as patented by Shandong Taikai) to achieve independent output of multiple windings, improve transformer efficiency and reduce harmonic interference, suitable for integrated photovoltaic energy storage systems.
● Shielding layer integration: Built in electromagnetic shielding layer to suppress common mode interference and high-frequency noise, ensuring stable output voltage (such as SSG series).
2 Insulation and cooling system
● H/F level insulation: The winding is treated with vacuum impregnation technology, and the insulation level reaches H level (180 ℃) or F level (155 ℃). The mechanical strength is improved by using a whole line winding method
● Dual mode cooling:
Natural air cooling (AN): allows continuous operation at 100% rated capacity;
Forced air cooling (AF): can increase capacity by 50% when overloaded, suitable for short-term emergency situations.
3 Intelligent installation innovation
● Yawei Transformer's patented lever type lifting structure simplifies the installation and maintenance of heavy-duty transformers using mechanical principles, improving operational efficiency
Applications
1 Renewable energy system
Integrated photovoltaic energy storage: integrating inverters and boost functions, reducing cable trench construction (such as the Taiping box transformer patent), and improving power station efficiency by more than 20%.
Wind power grid connection: Suitable for inverter multi winding output (2-6 groups), supporting grid connection in high harmonic environments.
2 Special industrial environment
Tunnel mine power supply: Boost the 380V input to 660V/1140V to solve the problem of voltage drop in long-distance transmission (such as Shanghai Yingshidan transformer).
Medical/precision equipment: Suppress common mode interference through △/Y conversion to ensure the power purity of precision instruments.
3 Emergency power system
Diesel generator matching (0.4kV → 0.69kV) provides fast boost backup power for data centers and hospitals.
Advantages
Outstanding safety performance
Adopting a non insulating oil design, it is fire-resistant and explosion-proof, completely eliminating the risks of oil leakage, combustion and explosion. It is suitable for densely populated places (shopping malls, hospitals, tunnels) and flammable and explosive environments (oil depots, chemical plants). Moreover, solid insulation materials (epoxy resin/glass fiber) can be recycled without the problem of waste oil treatment.
Efficient operation and maintenance with cost-effectiveness
Products with low loss are more energy-efficient. The no-load and load losses are significantly lower than those of oil immersed transformers (measured to be 15% -20% lower than the national standard), optimizing long-term operating costs.
Meanwhile, the equipment installation is simple and easy to maintain. Through optimized design, the finished product has a small volume and light weight, saving installation space by more than 30%; And no oil change maintenance is required, only regular dust removal is needed, reducing the complexity of operation and maintenance.
Strong environmental adaptability
The special pouring process for moisture and dust prevention (enclosed/pouring) ensures stable operation in high humidity and dust environments such as mines and tunnels. And carry out electromagnetic optimization design to reduce noise by 10-15 dB compared to oil immersed type, suitable for office areas and residential areas.
