As a professional manufacturer with over a decade of experience, Jinhua Dika Electrical Equipment Co., Ltd. specializes in providing reliable and efficient power solutions for industrial applications worldwide. Our Oil Cooled Transformer, 10kVA 19kV, is engineered to deliver dependable backup power for industrial substations, ensuring operational continuity and protecting critical equipment from voltage fluctuations. With a commitment to quality certified by ISO 9001 and other international standards, we design our transformers for durability, safety, and optimal performance in demanding environments. This product represents our dedication to supporting the global industrial sector with robust electrical infrastructure components.
This transformer is a cornerstone for maintaining power stability in industrial settings. Its core features and benefits are designed to meet the rigorous demands of backup power systems:
- Robust Construction for Longevity: The transformer features a high-grade silicon steel core and copper windings, which minimize no-load losses and ensure efficient energy transfer over a long service life. The tank is constructed from cold-rolled steel with anti-corrosion treatment, suitable for outdoor installation.
- Superior Cooling and Insulation: Utilizing mineral oil as both an insulating and cooling medium, the transformer effectively dissipates heat generated during operation. This natural oil-immersed (ONAN) cooling design ensures stable temperature management, preventing overheating and extending component life.
- Enhanced Safety and Protection: Equipped with a conservator tank with a silica gel breather to prevent moisture ingress, a pressure relief device for overpressure protection, and standard IP23 enclosure, it offers reliable protection against environmental factors.
- Flexible Configuration Options: We understand that industrial needs vary. Therefore, this 10kVA model offers customizable options including different tapping ranges, bushing types (porcelain or polymer), and the availability of temperature and oil level gauges for monitoring.
- Designed for Seamless Integration: Its compact and sturdy design facilitates easy installation in substation yards, either as a pole-mounted or pad-mounted unit, making it an ideal choice for backup power augmentation in existing industrial power networks.
Key technical specifications that define the performance of this transformer are summarized below:
| Parameter | Specification |

Frequently Asked Questions (FAQ)
-
Q: What is the primary application of this 10kVA 19kV oil-cooled transformer?
A: It is specifically designed as a backup power transformer for industrial substations. It ensures a continuous power supply to critical loads during main source interruptions or for voltage transformation within the substation's auxiliary power circuit. -
Q: Can this transformer be used indoors?
A: It is primarily designed for outdoor installation due to its oil-immersed design. For indoor use, specific safety regulations, containment provisions, and fire protection systems must be in place. We recommend consulting local electrical codes and our engineers for indoor application feasibility. -
Q: What are the standard delivery terms and lead time?
A: Standard delivery terms are FOB from our main ports (Shanghai, Tianjin, Guangzhou, Ningbo). The typical lead time for standard specifications is 4-6 weeks after order confirmation, subject to production schedule and order quantity. -
Q: Is the mineral oil included, and what are the environmental considerations?
A: Yes, the transformer is supplied filled with standard mineral insulating oil. For environmental-sensitive areas, we can offer biodegradable ester-based fluids as an optional alternative upon request. -
Q: Do you provide customization for different voltage ratios or frequencies?
A: Absolutely. While 19kV/400V is a common specification, we can customize the high voltage, low voltage, frequency (50Hz or 60Hz), and vector group to match your regional grid standards and specific application needs. -
Q: What kind of after-sales support and warranty do you offer?
A: We provide a standard warranty covering manufacturing defects. Comprehensive technical documentation, including test reports (routine tests), drawings, and installation manuals, are supplied. Remote technical support is available, and for major projects, on-site commissioning guidance can be arranged. -
Q: How energy-efficient is this transformer model?
A: Designed with low-loss core and winding materials, it offers competitive no-load and load loss values, contributing to lower total ownership cost through reduced electricity consumption over its lifespan. Specific efficiency data can be provided based on the final design parameters. -
Q: Are the bushings and accessories included?
A: Yes, the standard supply includes HV and LV bushings, a conservator with breather, a pressure relief device, and lifting lugs. Additional accessories like temperature indicators, marshalling boxes, or surge arresters are available as optional extras.
