Product Description

Features of SCB13 dry-type power transformer

Low loss: The no-load loss of the product is more than 20% lower than that of the SCB11 product, with 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 professional standard JB/T10088-1999 6-220KV Transformer Sound Level.

Low partial discharge: The resin mixed material adopts two technologies of foreign advanced stirring method and vacuum film degassing, so that the mixed material is stirred evenly and the air bubbles in the mixed material are eliminated. The product has only a very low partial discharge, which can be controlled below 5PC. Both high and low voltage coils are cast under vacuum and pressure, so that the resin insulation has both full encapsulation and inter-turn leaching. The casting body has a dense solidified structure, which is resistant, 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 of 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 reinforced concrete, so its mechanical strength is greater than that of pure epoxy resin, and it can withstand sudden short-circuit electrodynamic action without damage.

Product Usage

Residential quarters, high industry centers, factories and mines, airports, stations, schools and other places
