There are many transformer specifications, and different types of specifications have different meanings.
Common example: dry-type transformer
The meaning of "SCB10－1000KVA/10KV/0.4KV" dry-type transformer:
S means that the transformer is a three-phase transformer, and 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
Type of power transformer: usually consists of symbols that indicate the number of phases, cooling methods, voltage regulation methods, winding cores and other materials,
And it is composed of transformer capacity, rated voltage, and winding connection mode.
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 is 31500kVA
110: primary side rated voltage 110kV
