Complete Product Introduction

1. Product Brief Introduction

This transformer can replace transformers with silicon steel sheet cores and is widely used in outdoor power distribution systems. Extensive operation of this product can achieve excellent energy-saving effects and reduce low voltage and insufficient reactive power as well as voltage fluctuations in the atmosphere. It is not susceptible to atmospheric pollution due to insulation medium, so it can operate in humid environments. It is an ideal power distribution equipment in urban and rural power grids.

2. Model Meaning & Explanation

The coding of the product model contains the core structural characteristics and parameter information of the transformer. The specific meaning of each part of the model is as follows:

S: Three-phase
B: Copper wire low-voltage coil
H: Amorphous alloy core
15: Performance level code
M: Hermetically sealed structure
-□: Rated capacity (kVA)
/□: Voltage class (kV)

3. Executive Standards & Specifications

The design, production and inspection of the product are strictly in accordance with the following national and international standards to ensure product quality and performance compliance:

• GB1094.1-2013 Power Transformers
• GB1094.3-2003/GB/T1094.4-2005/GB1094.5-2008 Power Transformers

4. Structural Characteristics

• The transformer core is made of amorphous alloy strip wound, and the no-load loss is reduced by about 75% compared with S9 type transformers.
• The low-voltage coil uses copper wire winding to improve the transformer's ability to withstand short circuits.
• The transformer connection group adopts Dyn11 to reduce the impact of harmonics on the power grid and improve power supply quality.
• Vacuum oil injection is adopted to completely eliminate air bubbles in the coil and ensure stable insulation performance.

5. Operating Conditions

• Altitude does not exceed 1000 meters.
• Ambient temperature: maximum not higher than +40℃; maximum monthly average temperature +30℃; maximum annual average temperature +20℃; minimum temperature: -25℃.
• Outdoor or indoor installation.
