S11 Series 20KV Three-Phase Oil-Immersed Distribution Transformer
S11 Series 20KV Three-Phase Oil-Immersed Distribution Transformer

Description

This three-phase oil-immersed distribution transformer is with a new insulation structure to improve short-circuit resistance.


The iron core is made of high-quality cold-rolled silicon steel sheets. The high-voltage winding is made of high-quality oxygen-free copper wire and adopts a multi-layer cylindrical structure. All fasteners are treated with special anti-loosening treatment. 


The three-phase oil-immersed distribution transformer has the characteristics of high efficiency and low loss, which can save a lot of electricity consumption and operating costs, and has significant social benefits. It is a high-tech product promoted by country.

High-Quality Materials

◆ We use oxygen-free copper wire with lower resistance and a series of  additional surface treatments that result in a smoother surface with no burrs or sharp corners. This reduces the transformer's load losses and makes its electrical performance more reliable.


◆ We use high-quality silicon steel sheets and as the performance level increases, we adopt silicon steel sheets with lower unit losses to reduce the transformer's no-load losses.


◆ We use high-quality laminated wood insulation materials that never crack, even under short-circuit current, ensuring a more robust and reliable performance.


◆ We use transformer oil that has undergone deep filtration, resulting in lower levels of water, gas, and impurities. This enhances the reliability of the transformer's operation.


◆ We use high-quality rubber sealing materials that effectively prevent aging and eliminate leakage.


◆ All raw materials undergo quality inspection, and all raw material suppliers undergo strict review according to national standard IS09000.
