There are many transformer specifications, and different types of specifications have different meanings. Common examples: dry-type transformer "SCB10－1000KVA/10KV/0.4KV" dry-type transformer means: S means that the transformer is a three-phase transformer, if S is replaced by D, it means that the transformer is single-phase. C means that (dry-type transformer) windings are resin cast solids. B means foil winding, if it is R, it means winding winding, if it is L, it means aluminum winding, if it is Z, it means on-load voltage regulation (copper is not marked). 10 means the design serial number, also called the technical serial number. 1000KVA represents the rated capacity of this transformer (1000 kVA). 10KV means primary rated voltage, 0.4KV means secondary rated voltage. The meaning of common "power transformer" specifications and models: The model of a power transformer is usually composed of symbols that indicate the number of phases, cooling methods, voltage regulation methods, winding cores and other materials, as well as transformer capacity, rated voltage, and winding connection methods. For example: "SFSZ9-31500/110" transformer model meaning S: three-phase, F: air-cooled, S: three-winding, Z: on-load voltage regulation, 9: design number 9 type. 31500: rated capacity of 31500kVA 110: rated voltage of primary side 110kV
