66KV Electric Power Transformer

The 66kV power transformer is a medium- and high-voltage power transmission and distribution transformer designed and manufactured in strict accordance with GB and IEC standards. It utilizes oil-immersed insulation and cooling technology, using natural cooling, air cooling, water cooling, or forced oil circulation to ensure stable operation under various loads. Its core structure includes key components such as the core, windings, oil tank, oil pillow, radiator, insulating bushing, tap changer, and gas relay. Through comprehensive optimized design and precision manufacturing, it achieves a significant leap in product performance.

Core Product Features

1. Excellent Electrical and Mechanical Performance: Through our proprietary calculation and verification procedures, core components such as the core, coil, and leads are precisely optimized, resulting in products with high electrical and mechanical strength, capable of withstanding severe grid surges and short-circuit currents.

2. Energy-Saving, Environmentally Friendly, and Economically Efficient: The product features low losses (both no-load and loaded) and low noise levels, effectively reducing power station operating costs, complying with national industrial policies for energy conservation and consumption reduction, and enhancing the overall economic benefits of the power grid.

3. Extremely High Operational Reliability: The low partial discharge design and fully sealed, no-hanging core structure effectively prevent moisture and aging of the insulating oil, significantly reducing maintenance workload, extending the equipment life, and ensuring absolute long-term operational reliability.

4. Compact Structure and Superior Design: Superior craftsmanship and material selection ensure the transformer maintains performance while achieving the advantages of small size and light weight, facilitating transportation and installation, and saving space. The winding arrangement (core-low voltage-medium voltage-high voltage) of the step-down three-winding transformer is optimized to optimize impedance distribution and meet system protection requirements.

5. Excellent grid adaptability: One winding in the three-winding design is typically connected in a delta configuration, effectively suppressing third harmonics, improving voltage waveform quality, and ensuring high-standard adaptability to modern power grids.

Wide Applications

Due to their stable and reliable performance, the 66kV power transformer is suitable for a variety of harsh environments. Its main applications are:

Traditional power systems: major power plants and regional substations, serving as key nodes for power transmission and distribution.

Urban infrastructure: power supply systems in densely populated areas such as high-rise buildings, commercial centers, subways, airports, and train stations.
Large-scale industrial sectors: industrial and mining enterprises, petrochemical bases, and other locations with extremely high requirements for power supply continuity and safety.
Harsh environments: particularly suitable for offshore drilling platforms, oil production platforms, and special environments such as flammable and explosive environments. Its fully sealed and rugged structure provides extremely high safety assurance.
