Three Phase 400kV to 440V 60Hz Distribution Transformer

Product Description

PRODUCT HIGHLIGHTS
  • Using 99.9% oxygen-free pure copper windings (T2 copper). Compared to aluminum, it offers higher overload capacity, lower electrical resistance, and a significantly longer service life of up to 20+ years.
  • Engineered with high-permeability cold-rolled grain-oriented silicon steel cores. Our transformers are designed to meet or exceed IEC 60076 standards, reducing no-load losses by 20%-30% compared to standard models, saving significant operational costs for end-users.
  • Each unit undergoes a full suite of routine tests before dispatch, including transformation ratio, polarity, phase relation, and insulation resistance. Fully compliant with CE, ISO, and IEC international standards to ensure safe grid integration globally.

FAQs
Why does the price fluctuate, and how can I get the most accurate quote?
Our busbar accessories use high-purity copper as the core material, so the manufacturing cost is directly affected by global copper price fluctuations. To ensure you get the best deal, please contact us for a real-time quote based on today's raw material market prices and your specific order volume.
Do you support customization or OEM based on our specific drawings?
Yes, we are a professional manufacturer. We can customize the size, material, and even the plating of the contact pins and sockets according to your technical drawings or original samples. We have our own tooling facility to support rapid prototyping.
How do I ensure your accessories will fit my existing busbar system?
Compatibility is our top priority. Since different brands have different specifications, we highly recommend you provide your technical drawings or a clear photo of your current parts. Our engineering team will verify the dimensions to ensure a 100% perfect fit.
What international standards do your transformers comply with?
Our products are fully compliant with CE, ISO, and IEC international standards. Specifically, our transformers meet or exceed IEC 60076 standards to ensure safe and efficient grid integration globally.
What are the advantages of using 99.9% oxygen-free pure copper windings?
Compared to aluminum, T2 copper windings offer higher overload capacity, lower electrical resistance, and a significantly longer service life of up to 20+ years, ensuring long-term reliability.
How do your transformers help in reducing operational costs?
By using high-permeability cold-rolled grain-oriented silicon steel cores, our designs reduce no-load losses by 20%-30% compared to standard models, leading to significant energy and cost savings over time.
