10kV ZGS20-NX2 series combined transformer
This series of products is our company's leading product, featuring low loss, maintenance-free operation, convenient installation and maintenance, and reliable quality and safety, as detailed below:
1. This series of products uses high-performance 20RK70 silicon steel sheets and high-quality oxygen-free copper materials, which significantly reduces product loss and noise, and improves product performance;
2. The fully sealed structure eliminates contact between transformer oil and air, delays the aging of insulation materials, extends product lifespan, and greatly reduces daily maintenance work.
3. The coil structure with multi-segment circular arc smooth connection, which is independently developed by our company, can ensure that the radial dimension of the coil meets the requirements, while also increasing the effective cross-section of the iron core and ensuring that the iron core and the coil are tightly connected, which significantly reduces the no-load loss of the product and enhances the product's short-circuit resistance.
4. It adopts a corrugated plate heat dissipation structure, which has a good heat dissipation effect, an attractive appearance, and a small footprint.
