10kV Oil-Immersed Main Transformer

10kV oil-immersed transformers are designed for 10kV/0.4kV, 50Hz AC power distribution and voltage transformation systems. They are widely applicable to residential communities, commercial buildings, public facilities, industrial and mining enterprises, new energy power stations, industrial parks, and urban & rural power grid renovation projects.

All 10kV oil-immersed transformer products are strictly manufactured in accordance with Chinese national standard GB1094 and international standard IEC 60076, featuring reliable insulation performance, low loss, low noise, strong overload capacity and stable operational performance.

HY TRANSFORMER specializes in the R&D, production and sales of high-performance power transformers. Our 10kV oil-immersed transformer series covers S11, S13, S15 and other energy-saving models, including fully sealed and conservator-type structures. With compact structure, high efficiency and low maintenance requirements, these products are ideal solutions for conventional power distribution and new energy supporting power systems.

1. Superior Material Configuration & Advanced Manufacturing Technology

This 10kV oil-immersed transformer adopts ultra-low loss oriented silicon steel sheets and 100% oxygen-free copper coil windings, with high-insulation, anti-aging special transformer insulating oil filled inside. Adopting one-time vacuum drying and full-sealed integral forming process, the product effectively avoids oil leakage, moisture and dust intrusion. The overall structural rigidity is strong, which greatly extends the service life and guarantees long-term reliable operation of the equipment.

2. Ultra-low Energy Consumption & Excellent Operational Stability

Optimized for 10kV industrial and civil power distribution systems, the product adopts upgraded electromagnetic design structure. It effectively reduces no-load loss, load loss and operating noise, with uniform temperature rise and strong heat dissipation performance. It can adapt to peak power consumption, long-term full-load operation and harsh outdoor environmental conditions, maintaining efficient and stable power transformation for a long time.

3. Strong Scene Adaptability & Diversified Customization

The product features a highly versatile structural design, covering complete capacity specifications for 10kV power distribution. It supports targeted personalized optimization according to customer demands, including special voltage ratio, anti-corrosion treatment for outdoor use, low-temperature resistant configuration and special installation structure. It perfectly matches industrial parks, urban and rural power grids, photovoltaic energy storage projects, residential communities and other diverse application scenarios.

4. Strict Standard Production & High Safety Reliability

All products are manufactured and tested in full compliance with GB1094 national standards and IEC 60076 international industry specifications. Built-in multiple safety protection designs such as over-temperature protection, over-current protection and pressure relief protection, the equipment can automatically avoid operational faults. It features safe operation, no harmful emission, green and energy-saving performance, meeting global power industry safety and environmental access requirements.

5. Simple Installation & Low Lifecycle Operation Cost

With integrated compact design, small floor area and lightweight overall structure, the transformer is convenient for transportation, hoisting and on-site installation without complex auxiliary equipment. The product has extremely low failure rate and stable performance, requiring no frequent maintenance in daily operation. It effectively reduces later operation, maintenance and replacement costs for customers.

Q1: Are 10kV oil-immersed transformers available for photovoltaic power plants? Are their loss indicators compliant with IEC standards?

A: Absolutely. Our workshop can develop dedicated 10kV photovoltaic step-up transformers modified from standard oil-immersed transformers with full copper windings. Both no-load loss and load loss strictly satisfy the energy efficiency criteria specified in IEC 60076. Equipped with excellent anti-harmonic impact performance, they can also be deployed as general distribution transformers for industrial parks, mining areas and urban power grids.

Q2: What are the core operating merits of 10kV oil-immersed transformers against dry-type transformers?

A: Under identical rated capacity, oil-immersed transformers deliver lower manufacturing cost, outstanding heat dissipation efficiency, remarkable overload tolerance and extended service lifespan. They fit extensive application scenarios such as outdoor substations, rural power grids and centralized photovoltaic stations. Simple daily maintenance makes them the dominant transformer solution for 10kV power distribution and photovoltaic power transmission systems.
