As a professional manufacturer with over a decade of experience, Jinhua Dika Electrical Equipment Co., Ltd. specializes in delivering reliable and high-performance electrical solutions. Our 300 KVA Transformer with Mill Test Report is engineered for efficient voltage step-up applications, ensuring stable power transmission and distribution for your critical operations. We combine rigorous manufacturing processes with international quality standards to provide transformers that meet the diverse needs of global markets from North America and Europe to Southeast Asia and Africa.

This transformer is designed to elevate voltage levels effectively, making it an indispensable component in scenarios where power needs to be transmitted over long distances or integrated into higher voltage grids. Each unit is backed by a comprehensive Mill Test Report, providing transparent verification of material quality, workmanship, and performance characteristics, giving you confidence in your investment.

Core Product Features & Technical Advantages:

Precision Engineered for Voltage Step-up: Optimized design ensures minimal losses during the voltage transformation process, enhancing overall system efficiency.
Robust Construction: Utilizes high-grade grain-oriented silicon steel core and high-purity copper windings to ensure low no-load loss, low noise operation, and excellent short-circuit withstand capability.
Thermal Management: Advanced cooling design (ONAN/AN) ensures stable operation under full load, extending the service life of the transformer.
Customizable Configurations: Available in oil-immersed or dry-type insulation to suit different environmental and safety requirements. Frequency (50/60 Hz), voltage ratios, and tap changers can be customized.
Comprehensive Documentation: Each transformer is supplied with a complete Mill Test Report detailing raw material certificates, routine test results (ratio, polarity, winding resistance, insulation resistance), and other quality checks.

Detailed Technical Specifications:

Parameter	Specification	Remarks / Benefit
Rated Capacity	300 KVA	Ideal for medium-scale power distribution
Primary Voltage	Customizable (e.g., 11kV, 22kV)	Tailored to your grid input
Secondary Voltage	Customizable (e.g., 33kV, 66kV)	Achieves required step-up ratio
Frequency	50 Hz or 60 Hz	Compatible with regional power standards
Vector Group	Dyn11, YNd1, or others	Ensures proper phase relationship
Insulation Class	Class A, B, F, or H (Dry-type); Standard Oil (Oil-type)	Determines thermal withstand capability
Impedance Voltage	Typically 4% - 6% (customizable)	Affects short-circuit current and voltage regulation
Noise Level		Suitable for noise-sensitive environments

Benefits for Your Business:

Enhanced Grid Reliability: Stable voltage step-up minimizes fluctuations, protecting downstream equipment.

Frequently Asked Questions (FAQ)

What exactly is included in the Mill Test Report (MTR)?
The MTR is a detailed certificate that traces the transformer's manufacturing journey. It typically includes material certificates for core steel and winding copper, results of routine tests (turns ratio, polarity, winding resistance, insulation resistance), and sometimes dielectric and temperature rise test reports, providing full traceability.
Can this 300 KVA transformer be customized for a specific voltage ratio?
Yes, absolutely. As a manufacturer, we specialize in customizing the primary and secondary voltage ratings (e.g., stepping up from 11kV to 33kV) to match your specific grid requirements. Please provide your required input and output voltages during inquiry.
What is the typical delivery lead time for this product?
Lead time varies based on customization level and order quantity. For standard designs, it is typically within 30-45 days after order confirmation. We provide a more accurate timeline upon receipt of your detailed specifications.
Do you offer both oil-immersed and dry-type versions of this transformer?
Yes, we produce both types. Oil-immersed transformers are often used for outdoor applications, while dry-type transformers are preferred for indoor installations due to their non-flammable insulation. We can advise on the best type for your project.
How do you ensure the transformer complies with the standards of my country?
We design and manufacture transformers based on internationally recognized standards like IEC or ANSI. Upon request, we can also build to specific national standards. Clearly stating your required standard during the quotation process allows us to ensure compliance.
What are the key installation requirements for this transformer?
Installation requires a solid, level foundation, adequate clearance for ventilation and maintenance, proper cable terminations, and earthing. We provide detailed installation manuals. For oil-filled units, a containment bund may be required by local regulations.
What warranty and after-sales support do you provide?
Our transformers come with a standard warranty covering manufacturing defects. We also offer comprehensive after-sales support, including technical documentation, remote troubleshooting guidance, and access to spare parts.
Can you provide references or case studies from similar projects?
Yes, we can share relevant case studies or customer testimonials upon request. Our experience supplying to diverse global markets demonstrates our capability to handle various project requirements.
