The three-phase oil-immersed distribution transformer produced by our company adopts a new insulation structure to improve the ability of resisting short circuit. The iron core is made of high quality cold rolled silicon steel sheet. The high voltage winding is made of high quality oxygen free copper wire. Multi-layer circular structure is adopted and all fasteners are treated with special anti-loosening.
The product has the characteristics of high efficiency and low loss, it can save a lot of electricity consumption and operation cost, and the social benefit is remarkable. It is a high and new technology product popularized by the country.
On the basis of traditional structure and mature technology, our company has made many improvements, such as adopting:
Spiral coil with longitudinal oil passage, better internal heat dissipation;
The effective support of coil end face is improved, and the ability to resist short-circuit current is stronger.
New hoisting structure and positioning structure of the body are adopted to ensure more reliability in long-distance transportation and operation.
We also have many unique and reliable structures for your service;
Select the transformer with higher performance level, will have a higher level of technical content.
High quality materials
With the choice of oxygen free copper wire with lower resistivity and a series of additional surface treatment, the transformer has lower load loss and more reliable electrical performance because of its smooth and burr free angle.
Select high quality silicon steel sheet, with the improvement of performance level, adopt unit loss, lower silicon steel sheet, make transformer no-load loss lower.
Using high-quality laminated wood insulation, it will never crack and will not move even under the action of short-circuit current.
Select transformer oil through deep filtration, lower water, gas, impurity level, transformer work more reliable. Select high-quality rubber sealing material, effective anti-aging, prevent leakage.
All raw materials have passed quality inspection, and all raw material manufacturers have passed strict examination according to the national standard IS O9000.
Good technical and economic performance
TS9 series products reduce no-load loss, load loss and no-load current. Compared with TS7 series, they are reduced by 10%ã4% and 46% respectively, thus reducing the operating cost by 19 %.
On the basis of TS9 series, the no-load loss of TS11 series products has been reduced by 30 % on average. No-load current ratio TS9 decreased by 70-85%; The average temperature rise decreased by 10K, the service life of the product more than doubled, and it can still run for a long time even under the condition of 20 % overload.
The operating noise of the product is reduced by 2-4 decibels on average
