Three-Phase No Excitation Voltage Regulation Power Transformer

The performance indicators of the dry-type transformers produced by our company comply with various standards, and the operation is proved to be reliable by the user's application, reaching the domestic advanced level. This series of products adopts foreign advanced manufacturing technology, complete design drawings and technical documents are complete, correct and clear, advanced production equipment, stable manufacturing process, complete test means, provides a solid guarantee for the production of excellent products.

The no-load loss of the product is more than 20% lower than that of the SCB10 type product, and the load loss is more than 30% lower than that of the SCB10 type product.

The noise level of the product is 10-15 dB lower than the current professional standard JB / T10088-2016 "Sound Level of 6-220KV Transformer".

The resin mixture adopts two advanced foreign mixing methods and vacuum film degassing technology, which makes the mixture evenly stirred and completely eliminates the bubbles in the mixture. The product has extremely low partial discharge, which can be controlled below 5PC. The high and low voltage coils are cast under vacuum and pressure, so that the resin insulation has both full encapsulation and interlayer turn dipping. The casting body has a dense curing structure, flame retardant, explosion-proof, and does not pollute the environment. Insulation materials such as glass fiber wound coils have self-extinguishing characteristics, and will not generate arcs due to short circuits, and resins will not produce toxic and harmful gases under high heat.

The shell is made of stainless steel or plastic-sprayed iron. The protection level is up to P20/P23, and the IP20 shell can prevent direct solid foreign matters greater than 12MM from entering the transformer for further safety protection. The IP23 shell also prevents water droplets from flowing into the vertical line at 60 angles, which is suitable for outdoor operation.
