The specific meaning of the type of dry-type transformer

Type of dry-type transformer customer in

　　

Common dry-type transformer models are SC10, SC11, SCB10, SCB11, SCB12, SCB13, Sh15, SG and so on. 1. SC AND SCB dry-type transformers are dry-type transformers which are insulated by liquid epoxy resin. The whole body of the transformers is red SG series transformers are non-encapsulated Class H normac dupont paint for the insulation material, the transformer body for the metal copper color. 2. Iron core material SC, SCB, SG dry-type transformer iron core material is silicon steel sheet, silicon steel sheet material strength is big, tensile strength is high, can adapt to short time overload. But SH15 series belongs to the non-gold Alloy material, material strength is small, the tensile ability is low, bears the sudden short ability to be poor. 3. energy-saving level (no-load loss) the most important component that affects no-load loss is the iron core. The no-load loss of silicon steel sheet is greater than that of non-alloy, the smaller the no-load loss. The order of loss from high to low is: SCB10 & GT; SCB11 & GT; SCB12 & GT; Scb13 & GT; SH15. 4. Letter order and meaning S: Phase Number, three-phase Transformer C (G) : dielectric C FOR EPOXY CAST insulation, G FOR AIR INSULATION B: low-voltage Winding Material B for low-voltage winding foil, no identification means that the low voltage winding is wire winding. 10: Performance Code, followed by the number of this transformer is the energy-saving level, the higher the number, that the overall energy-saving transformer is relatively high.
