6 kV 6.6 kV 7.2 kV 10kV High Voltage H61 H59 Distribution Transformer (Oil immersed)

Product Description

The S Series 10KV Class H61/H59 oil-immersed power transformer is a core equipment specially designed for medium-voltage power distribution scenarios. It precisely meets the stable transmission needs of industrial production and civil electricity use, and has become a preferred solution for power grid construction with its reliable quality.

As a benchmark product in the 10KV class, its material advantages are particularly prominent. The core conductive components are made of high-purity H61/H59 copper alloy, with electrical conductivity 12% higher than ordinary materials and no-load loss reduced by 18%. It not only reduces energy waste but also enhances corrosion resistance and anti-aging performance, making it suitable for long-term outdoor operation. The oil-immersed design, combined with special insulating oil and Class H insulation structure, ensures insulation resistance stable above 1000MΩ and full-load operating temperature controlled within 85℃, effectively resisting the risk of high-voltage breakdown.

Widely used in industrial park production lines, commercial complex power distribution networks, urban and rural power grid transformation and other scenarios, the combination of 10KV high-voltage input and flexible low-voltage output can match different load requirements on demand. Relying on 10 years of professional transformer manufacturing experience, each equipment has passed IEC 60076 standard certification and authoritative type tests, holding complete test reports, with a design service life of 20 years.

Features

The three-phase oil-immersed distribution transformer applies new type insulating structure. The iron core is made high-quality cold-rolled silicon-steel plate. High-voltage winding group is made up of high-quality oxygen-free copper lines and it adopts multilayered drum type structure. All fasteners have been processed with special treatment to prevent them from loosening.
As high-tech product that promoted by the country. the product has many advantages such as high efficiency, low loss. Its social benefits are remarkable that it will save much of electricity consumption and operating cost.

Advantage of structure

1. we employ sprial coil with longitudinal oil path to make a better interior cooling effect;

2. we improve the effective support of the coil's terminal surface to strengthen the anti-short circuit current capability;

3. we employ new hoisting structure and body-positioning frames to guarantee that the long distance transport and movement will be more reliable;

4. cancelled the oil tank, the wave wings of tank instead of the tubing as a cooling device, corrugated tank is made of high quality cold press sheet on dedicated machine and enhance the reliability of running.

Advantage of materials 

1. because we use oxygen-free copper lines of lower resistivity, which will become smoother and burr-free after series of additional surface treatment, so the load loss of our transformer is lower and the electric performance is better.

2. We use high-quality silicon-steel plates which are of lower unit loss, and no-load of the transformers is lower;

3. We use high-quality wooden laminating insulation pieces, which won't split or move even under the influence of short circuit;

4. We use thoroughly filtrated transformer oil containing less water ,gas and impurities, which makes our transformer work better;

5. We use high-quality rubber sealing material, which can prevent the transformers form aging or leakage;

6. All materials has passed the quality testing, and all the raw material factories has pass through the national standard ISO9000 inspection.

Advantage of technology

Improved from S9 series product, S11 series product reduce the no-load loss by 30%,no-load electric current by 70~85%, average temperature by 10K,nosie level by 2~4db, and double the products service life. even under 20% overloads, it can also work for long period of time .
