SC(B)13 dry-type transformer

Product Description

Low loss: The no-load loss of the product is reduced by more than 30% compared with the SCB10 type product, and the load loss is reduced by more than 10% compared with the SCB11 type product. It has excellent energy saving effect, economical operation and maintenance-free.

Low noise: The noise level of the product is more than 10-15 decibels lower than the current standard JB/T10088-2016 "6-220KV Transformer Sound Level"

Low partial discharge: The resin mixture adopts two technologies of foreign advanced stirring method and vacuum film degassing, so that the mixture is stirred evenly and the air bubbles in the mixture are excluded. The product has only low partial discharge and can be controlled below 5PC. Both the high and low voltage coils are cast under vacuum and pressure, making the resin insulation both fully encapsulated and inter-turn leaching. The casting body has a dense curing structure, which is flame-retardant, explosion-proof and does not pollute the environment. Insulation materials such as glass fiber wrapped around the coil have self-extinguishing properties, and will not generate arcs due to short circuits, and the resin will not produce toxic and harmful gases under high heat.

High mechanical strength: The resin with filler makes the difference in the expansion coefficient of the casting body small, the curing shrinkage rate is small, the internal stress is small, and the hardness of the cured product is high. The prefabricated reinforcing material has a dense structure like steel bars and concrete, so its mechanical strength is greater than that of pure epoxy resin, and it can withstand sudden short-circuit electrodynamic action without damage.
