SCB11 Type Dry-Type Transformer

1. High performance and low loss, a replacement product for the Type 9 series.

2. Utilizes high-quality silicon steel sheets, while significantly reducing magnetic flux density and magnetostriction of the silicon steel sheets during operation, effectively reducing noise.

3. Optimized high-voltage coil structure improves the distribution of interlayer voltage and capacitance, greatly enhancing the product's ability to withstand atmospheric and operational overvoltages. It also improves the electric field distribution, further reducing partial discharge.

4. Can be configured with a temperature control system and air-cooling device, automatically activating the fan cooling system under excessive load, effectively improving the equipment's overload capacity.

SCB11-30～20000KVA/35KV dry-type transformer structural features:

1. The core uses high-quality cold-rolled grain-oriented silicon steel sheets. The silicon steel sheets in the core use a 45-degree fully oblique joint, so that the magnetic flux passes along the joint direction of the silicon steel sheets.

2. The windings are of the following types: (1) wound type (2) epoxy resin and quartz sand filling casting (3) glass fiber reinforced epoxy resin casting (i.e., thin insulation structure) (4) multi-strand glass fiber impregnated epoxy resin wound type (generally, type 3 is more commonly used because it can effectively prevent the casting resin from cracking and improve the reliability of the equipment)

3. The high-voltage winding generally adopts a multi-layer cylindrical or multi-layer segmented structure.

4. The low-voltage winding generally adopts a layered or foil structure.
