10kV SC(B) series three-phase cast resin dry-type power transformer application scenarios and solutions

Application scenarios ‌

1. Urban power grid and commercial center ‌

With the acceleration of urbanization, the demand for electricity has surged. Traditional oil-immersed transformers are difficult to meet the power distribution requirements of densely populated areas due to defects such as large size and flammability. SC(B) series dry-type transformers, with their fireproof and explosion-proof features and compact size, can be directly installed in substations, commercial complexes or underground distribution rooms in urban core areas, optimizing grid layout, reducing line losses, and ensuring the efficiency and safety of urban power supply.

2. High-rise buildings and data centers

High-rise buildings have extremely high requirements for power supply reliability and need to adapt to limited space environments. This series of transformers are maintenance-free and pollution-free. They can be deployed in the internal distribution layer or basement of the building. With the intelligent temperature control system, they monitor the operating status in real time to avoid failures caused by overheating and ensure continuous power supply to highly sensitive loads such as elevators, fire protection systems, and data centers.

3. Transportation hubs and infrastructure

Airports and railway stations. They need to deal with large-capacity power fluctuations and complex electromagnetic environments. The transformer adopts the copper foil winding process and anti-short-circuit design to ensure stable operation during sudden load changes. At the same time, the low noise characteristics meet the environmental protection requirements of public areas.

Tunnels and subways. The environment is humid and ventilation is limited. The epoxy resin casting structure has excellent moisture and corrosion resistance. Combined with the split thermostat and axial flow fan to enhance heat dissipation, it is suitable for long-term operation in confined spaces.

Offshore platforms and ships. In high salt fog and high vibration scenarios, its fully sealed insulation structure and mechanical shock resistance can avoid insulation failure caused by environmental corrosion and ensure the safety of offshore power.

4. New energy and industrial fields

Large hydropower stations/photovoltaic power stations. Intelligent grid management is required. It is interconnected with the central control system through the RS485 interface to support remote monitoring and fault warning, and improve the efficiency of new energy grid connection.

Manufacturing factories. For current shocks caused by frequent start-stop equipment, the transformer's low-loss silicon steel sheet core and anti-sudden short-circuit capability can reduce energy consumption and extend equipment life.

 

Solution highlights

Safe and reliable

Fireproof and explosion-proof. The epoxy resin casting coil reaches F-class insulation and contains no flammable substances, meeting the fire protection requirements of high-risk areas such as high-rise buildings and petrochemical plants.

Intelligent monitoring. The built-in temperature controller realizes over-temperature alarm, tripping and fault recording (black box function), and combined with the remote communication interface (RS485), it supports centralized management in unattended scenarios.

High efficiency and energy saving ‌

Low loss design ‌: The 45° inclined seam core process reduces the no-load loss by more than 30%, and the H-class insulation material can withstand high temperatures, allowing short-term overload operation and reducing capacity redundancy configuration.

Dynamic heat dissipation ‌: The independent axial flow fan starts and stops on demand, combined with the multi-stage circular cross-section core structure, to improve the heat dissipation efficiency and extend the insulation life.

Environmentally friendly ‌

Zero pollution. There is no risk of oily medium leakage, suitable for sensitive places such as ecological protection areas and hospitals.

Low noise. The five-step stacking process and shock-absorbing clip design have an operating noise of <55dB (within 1 meter), which meets the city's nighttime power supply needs.

Flexible adaptation ‌

Modular expansion. The capacity covers 30kVA~2500kVA, supports multiple units in parallel or customized voltage levels, and is suitable for emerging scenarios such as distributed energy and microgrids.

Compact installation. The weight is 40% lighter than that of oil-immersed transformers of the same capacity, and it can be directly deployed in small spaces such as rooftops and container substations.

SC(B) series dry-type Power Transformers have become the preferred equipment for modern power systems due to their high safety, intelligent management and environmental adaptability. Its applications cover many fields such as urban infrastructure, industrial manufacturing, transportation and energy, and are particularly suitable for scenarios with limited space, harsh environments or strict fire protection requirements, helping customers build efficient, low-carbon and highly reliable distribution networks.
