Shanxi Jurun Technology Co., Ltd., located in the industrial hub of Taiyuan, Shanxi, China, specializes in manufacturing premium electromagnetic pure iron coils engineered for transformer core applications. Our DT4C grade material offers exceptional magnetic properties that significantly enhance energy efficiency in electrical equipment.
Engineered for precision performance, these coils undergo rigorous quality control to ensure consistent magnetic permeability and minimal core losses. With thickness options ranging from 0.5mm to 2.0mm, our products cater to diverse transformer design requirements across power distribution networks and industrial applications.
The DT4C electromagnetic pure iron features:
- Ultra-low hysteresis losses for reduced heat generation
- High saturation induction (up to 2.2T)
- Consistent thickness tolerance within ±0.03mm
- Optimal lamination characteristics for stacked cores
Technical Specifications:
| Property | Value |
| Core Loss (W/kg) @ 1.5T/50Hz | 3.2-4.1 |
| Relative Permeability | ≥ 5000 |
| Coil Width | 100-1200mm (custom) |
| Surface Insulation Resistance | ≥ 20 Ω·cm² |
Our manufacturing process includes vacuum degassing to achieve purity levels exceeding 99.8%, resulting in superior magnetic consistency. The annealing treatment in hydrogen atmosphere ensures excellent ductility for precision stamping operations. These coils demonstrate remarkable stability under varying operational temperatures from -40°C to +150°C.
Applications Include:
- Power transformers (distribution & transmission)
- Current transformers & instrument transformers
- Induction heating equipment
- Electric vehicle charging stations
With an annual production capacity exceeding 12,000 metric tons, Shanxi Jurun Technology provides reliable supply chain solutions for global transformer manufacturers. Our vertically integrated facility allows strict control over metallurgical composition and processing parameters, ensuring batch-to-batch consistency. The coils are available with optional tension leveling for enhanced flatness requirements in high-speed stamping applications.
For projects requiring specific performance characteristics, our engineering team offers technical consultation to optimize material selection based on your operating frequency, flux density, and loss requirements. Customized slitting services are available to deliver ready-to-use strips for your laminating production lines.
Frequently Asked Questions:
Q1: Why choose DT4C grade over conventional electrical steels?
A: DT4C pure iron offers approximately 15-20% lower hysteresis losses compared to conventional non-oriented electrical steels, particularly beneficial for high-efficiency transformers operating at medium frequencies.
Q2: Can you supply thinner gauges below 0.5mm?
A: While our standard production range starts at 0.5mm, we can produce down to 0.35mm for specialized applications with adjusted minimum order quantities.
Q3: What protective coatings are available?
A: We typically supply bare coils, but can apply C-5 oxidation resistance treatment or inorganic insulation coatings upon request.
Q4: How do you ensure dimensional accuracy?
A: Our rolling mills incorporate laser thickness gauges with automatic feedback control, maintaining thickness tolerance within ±0.03mm across the coil width.
Q5: What is your standard delivery lead time?
A: For standard specifications, we maintain 30-45 days from order confirmation. Urgent orders can be prioritized with production slot allocation.
Q6: Do you provide material certification?
A: Yes, we supply comprehensive mill test certificates including chemical composition, magnetic properties, and mechanical characteristics with each shipment.
