As a dedicated manufacturer with over a decade of experience in power equipment, Jinhua Dika Electrical Equipment Co., Ltd. specializes in producing reliable and efficient distribution transformers for global markets. Our Single Phase Oil Transformer, available from 10kVA to 15kVA, is engineered to deliver stable and safe power conversion in demanding environments. Designed with versatility in mind, it supports multiple primary voltage ratings including 11kV, 15kV, 19kV, and 25kV, making it an ideal solution for extending grid networks, powering remote communities, and supporting industrial applications. We combine robust manufacturing processes with stringent quality control, backed by our ISO 9001 management system, to ensure every unit meets high performance standards.

Core Product Features & Technical Advantages:

Robust Construction for Longevity: The transformer core is built using high-grade, grain-oriented silicon steel laminations, which are meticulously stacked and clamped. This design minimizes core losses (no-load losses) and reduces audible noise, leading to higher overall efficiency and a longer operational lifespan, even under continuous load.
Superior Insulation and Cooling System: Immersed in high-quality, stabilized mineral oil, the windings and core are effectively insulated and cooled. The oil acts as both an electrical insulator and a heat transfer medium. The ONAN (Oil Natural Air Natural) cooling method allows for natural convection of oil and air, ensuring reliable thermal management without moving parts, which reduces maintenance needs.
Flexible Voltage Configuration: Understanding that grid standards vary, we offer this transformer with customizable primary voltage taps. The standard offerings include 11kV, 15kV, 19kV, and 25kV, allowing for seamless integration into diverse distribution networks without the need for additional external equipment.
Designed for Easy Installation and Service: Featuring clearly marked terminals, accessible pressure relief devices, and a conservator tank with oil level gauge, the transformer is designed for straightforward installation, whether pole-mounted or on a concrete pad. This user-centric design reduces installation time and costs for our clients.
Enhanced Safety Features: Safety is paramount. The transformer includes a pressure relief valve to safely vent internal gases under fault conditions, a silica gel breather to keep moisture out of the oil, and robust bushings designed for high dielectric strength, protecting both the equipment and personnel.

Frequently Asked Questions (FAQ):

Q: What is the typical delivery lead time for a 15kVA, 11kV model?
A: For standard configurations, the lead time is typically 4-6 weeks after order confirmation. This includes manufacturing, testing, and preparation for shipment. Expedited options may be available upon request.
Q: Can the secondary (LV) output voltage be customized?
A: Yes, absolutely. While common outputs like 120/240V or 230V are standard, we can customize the low-voltage winding to match your local distribution standard or specific equipment needs. Please specify your requirement during inquiry.
Q: What kind of testing is performed before shipment?
A: Every transformer undergoes routine tests as per IEC 60076, which include but are not limited to: Ratio and Polarity Test, Winding Resistance Measurement, No-Load Loss & Current Test, Load Loss & Impedance Voltage Test, and Dielectric Tests (Induced Overvoltage and Separate Source Voltage). Test reports are available.
Q: Is this transformer suitable for outdoor installation without a shelter?
A: Yes, it is designed for outdoor service. The tank is constructed from corrosion-resistant steel with a durable paint finish. The oil and bushings are designed to withstand outdoor environmental conditions like rain, sun, and moderate pollution. Proper grounding is essential.
Q: What are the main maintenance requirements?
A: Maintenance is minimal. Key checks include periodic visual inspection for leaks, monitoring the oil level via the gauge, checking the color of the silica gel in the breather (replacing if saturated), and periodic electrical testing as recommended by maintenance standards.
Q: Do you provide installation guidance or technical support?
A: Yes, we provide detailed installation and operation manuals with each unit. Furthermore, our technical team is available to answer questions and provide support via email or online meetings to ensure successful commissioning.
Q: Are spare parts like bushings and gaskets readily available?
A: We maintain an inventory of common spare parts and can supply them as needed. It is recommended to inquire about a spare parts kit at the time of order for critical components to reduce future downtime.
Q: How does the efficiency of this oil transformer compare to dry-type transformers?
A: Oil-immersed transformers generally offer higher efficiency and better heat dissipation for the same rating, leading to lower operating losses. They are also often more cost-effective for distribution-level voltages. Dry-types are preferred where fire safety indoors is a primary concern.
