Product Introduction
I. General Product Overview
The SCBH15/17/19 series are 6kV, 10kV, and 20kV non-ferromagnetic alloy dry-type power transformers. They are composed of non-ferromagnetic alloy cores and epoxy resin-impregnated windings, featuring extremely low no-load loss, oil-free fire prevention, environmental protection, and maintenance-free core advantages. They are widely used in urban power grids, commercial complexes, hospitals, data centers, rail transit, and places with high energy-saving requirements. They are designed and manufactured in accordance with the national standard management committee based on the standards of GB 20052-2024 "Energy Efficiency Limits and Energy Efficiency Grades for Power Transformers" and GB/T 22072.
Model Meaning: S = three-phase; C = resin casting; B = low-voltage foil type; H = non-ferromagnetic alloy core; 15/17/19 = performance sequence (corresponding to energy efficiency grades).
Voltage Levels: High voltage 6/10/20kV, low voltage 0.4kV (standard).
Capacity Range: 30kVA to 2500kVA (6/10kV); 30kVA to 10000kVA (20kV).
Cooling and Insulation: AN/AF air cooling; insulation grade F (155℃), optional H grade for high-temperature tolerance.
Protection and Compatibility: Standard IP20, optional IP30/IP54; support temperature control, fan, RS485 intelligent monitoring.

II. Series Core Comparison (GB 20052-2024)
SCBH15 is a third-level energy efficiency model, serving as the benchmark for this series. It features mature technology and the lowest cost, and is a popular product, commonly used for retrofitting existing facilities, replacing old equipment, and projects with relatively limited budgets.
SCBH17 is a second-level energy efficiency model (NX2), with a reduction of approximately 15% in no-load loss compared to SCBH15. The energy-saving effect is significant, and the overall size is smaller, suitable for various new construction projects, such as commercial buildings, hospitals, schools, and general industrial projects.
SCBH19 is a first-level energy efficiency model (NX1), with a reduction of 25% to 30% in no-load loss compared to SCBH15. It reaches the ultimate energy-saving level of this series and also has an ultra-quiet feature, with operating noise ≤ 45 dB. The service life is longer, and it is mainly used in data centers, power grid hub sites, areas with high electricity prices, and key projects that require long-term continuous operation and focus on the carbon neutrality goal.

III. Key Technologies and Advantages
1. Amorphous alloy core: The atoms are randomly arranged, resulting in magnetic hysteresis loss only being 1/3 of that of traditional silicon steel sheets, and the no-load loss is significantly reduced.
2. Fully sealed casting: The windings are vacuum-pressure epoxy cast, providing excellent protection against short circuits, moisture, dust, and local discharge ≤ 10 pC. The maintenance-free life can reach 30 years +.
3. Safe and Environmentally Friendly: Oil-free, flame-retardant and self-extinguishing. It can be placed in the load center and indoor sensitive areas, meeting green and low-carbon as well as fire safety requirements.
4. Intelligent Adaptation: Supports temperature control linkage, automatic fan start-stop, RS485 / Internet of Things remote monitoring, and is compatible with smart power distribution.

IV. Key Points for Voltage Selection at 6/10/20 kV
6 kV: Suitable for small-scale systems in old industries, mines, and metallurgy. The capacity is relatively small and its application is gradually decreasing.
10 kV: The mainstream in urban distribution networks. It has the most complete models and the strongest versatility, covering residential areas, commercial areas, and industrial areas.
20 kV: The preferred choice for new parks, large-scale industries, and new areas of the power grid. It has a larger transmission capacity, lower line loss, longer power supply radius, and better overall economic performance.
V. Selection Suggestions and Economic Considerations
Priority: New construction projects should preferentially select SCBH17/19; for replacement and renovation, SCBH15 can be used to control costs.
Payback Period: The initial investment of the first-level energy efficiency (SCBH19) is approximately 30% higher, but the annual electricity savings are significant, and it can be recovered within 3 to 5 years (calculated based on an electricity price of ≥ 0.7 yuan/kWh and annual operation ≥ 5000 hours).
Scenario Matching:
Commercial / Hospitals / Schools: Select SCBH17, balancing energy savings and cost.
Data centers / Hub power grids / High electricity prices: Select SCBH19, achieving ultimate energy savings and reliability.
