|Product features of SC(B)13 type three dimensional wound core dry type transformer (compared with conventional superimposed core transformer)
Low loss: three dimensional wound core dry type transformer has little seamless reluctance, close winding, high fill factor and light core weight. Compared with conventional laminated core dry type transformer, no-load loss Po can reduce 18%～28%. No-load current Io reduce 50%～60%. It has significant energy-saving effect and economical operation.
Low noise: noise level of three dimensional wound core dry type transformer was 5～10db lower than conventional laminated core dry type transformer, and 15～20 db lower than professional standard JB/T10088-2004
Low partial discharge levels: Resin mixture use advanced foreign stirring method and vacuum film degassing, it will mix the mixture evenly, exclude bubble from compound, high and low voltage windings are all poured under vacuum pressure, resin insulation is fully wrapped, layers have complete permeability. Partial discharge quantity of products controlled under 5PC. Casting body has compact curing structure, it is flame retardant, anti-explosive and will not pollute the environment.
High mechanical strength: Three dimensional wound core use orbicular core section, anti-short circuit ability is better than oval section. Filled resin will lessen dilatation coefficient difference, cure shrinkage rate and innerstress, elevate curing hardness. Prefabricated forming strengthening material in epikote encapsulated layer will make mechanical strength much larger than pure epoxy resin, so the product can bear sudden short circuit without damage.
