Key Features
Energy Efficient: This transformer is engineered with an advanced design to drastically reduce core and coil losses, thereby achieving a new level of unmatched energy conversion efficiency and significantly lowering operating energy consumption, resulting in exceptional cost savings.
Low Loss: Crafted from premium-grade silicon steel sheets using cutting-edge manufacturing techniques, it effectively minimizes no-load and load losses, ensuring that the power system operates at a significantly lower cost.
Excellent Heat Dissipation: Utilizing oil as a cooling medium, it achieves outstanding heat dissipation through natural convection or forced oil circulation, ensuring reliable performance even under high load conditions and extending the life of the equipment.
Environmentally Friendly Design: Compliant with both national and international energy-saving and environmental standards, this design significantly reduces carbon emissions and environmental pollution, making it an ideal choice for sustainable energy projects and modern, eco-conscious power grids.
Safe and Reliable: The use of high-strength insulation materials, combined with meticulous engineering, ensures safe and stable operation—even in the most demanding grid environments.
Scientific Computing Methods
Advanced computing software is used for electromagnetic, thermal, and mechanical calculations to analyze the distribution of electromagnetic fields and magnetic leakage, determine insulation tolerances, and study wave processes. Simulation design is performed using two-dimensional and three-dimensional dynamic models, ensuring reliable performance and a rational structure.
Rational Structural Arrangement
Based on computational results, rational choices are made for insulation structure, wire specifications, and magnetic flux density.
- A magnetic shield is applied to the oil tank.
- The natural vibration frequencies of the clamping plate and iron core are calculated.
- A multi-step, fully oblique lap-joint structure is adopted.
- Round bars and cardboard sleeves are used to improve short-circuit resistance.
- Partial discharge is reduced by applying a rounding process to the edges of insulation and internal metal parts.
Advanced Processing Methods
- The iron core is cut automatically with high precision and minimal burrs.
- Non-overlapping upper yoke processing is used.
- A double-H setting glue is applied to surfaces.
- Wires are wound vertically using a numerically controlled tension device.
- Set-assembly is adopted for the transformer body, and integral pre-assembly is used for wire leads.
- A fully automatic gas-kerosene drying process is applied to the transformer body.
- Pre-assembly is also adopted during general assembly.
Comprehensive Quality Assurance System
Product quality is controlled according to ISO 9001 quality standards.
Systematic Data Management
ERP and PDM data management systems are used throughout the entire process, from sales to final delivery.
