As a specialized manufacturer based in Taiyuan, Shanxi, Shanxi Jurun Technology Co., Ltd. produces premium 0.8mm DT4C cold rolled coils specifically engineered for transformer core applications. Our material delivers exceptional magnetic properties that directly impact transformer efficiency and performance. With precise thickness control and superior surface quality, we help manufacturers achieve higher yields and consistent core production.
This specialized electrical steel is manufactured using advanced cold rolling techniques that optimize grain orientation for maximum magnetic flux efficiency. The DT4C grade offers an optimal balance between core loss reduction and magnetization characteristics, making it ideal for power transformers operating under demanding conditions.
Key Technical Features:
- Ultra-Low Iron Loss: Significantly reduces energy dissipation in transformer cores
- High Permeability: Enables efficient magnetic flux transfer
- Precision Thickness Control: ±0.02mm tolerance ensures stacking accuracy
- Optimized Surface Quality: Minimizes interlaminar resistance
- Consistent Mechanical Properties: Uniform hardness (45-55 HRB) for precise punching
Our coils are available in various widths to accommodate different transformer designs and production requirements. The material can be supplied with or without insulation coating depending on your specific application needs.
Typical Performance Parameters:
| Property | Value | Test Condition |
|---|---|---|
| Core Loss (P1.5/50) | ≤ 3.8 W/kg | 1.5T @ 50Hz |
| Magnetic Induction (B50) | ≥ 1.65 T | 5000 A/m |
| Density | 7.65 g/cm³ | Standard |
| Resistivity | 0.47 μΩ·m | Standard |
The material's unique crystalline structure provides excellent directional magnetic properties that align perfectly with transformer core design requirements. When processed into laminations, our coils contribute to:
- Reduced no-load losses (up to 15% improvement versus standard grades)
- Lower operating temperatures for extended transformer lifespan
- Reduced audible noise during transformer operation
- Enhanced efficiency compliance with international energy standards
For transformer manufacturers seeking to improve their competitive edge, our 0.8mm DT4C cold rolled coil offers tangible benefits throughout the production chain. The material's dimensional stability reduces scrap during punching operations, while the consistent magnetic properties ensure uniform performance across all laminations.
Shanxi Jurun Technology leverages its strategic location in China's industrial heartland to deliver responsive service and technical support to transformer manufacturers worldwide. Our production facilities implement rigorous quality control measures at every stage, from material selection to final inspection. We maintain extensive material traceability to ensure consistent performance batch after batch.
The combination of our technical expertise in electrical steel production and deep understanding of transformer manufacturing requirements positions us as a valuable partner for your core material needs. We invite you to discuss your specific application requirements and explore how our DT4C cold rolled coil can enhance your transformer performance while reducing total ownership costs.
