Abstract
The utility model discloses a dry-type transformer which comprises a clamping piece, an iron core, a coil and a base, wherein an elastic vibration isolation material is arranged between the iron core and the clamping piece as well as between the iron core and the base, so as to completely insulate the iron core from the clamping piece as well as insulate the iron core from the base. Due to the elastic vibration isolation material, the mechanical collision strength between the iron core and the base as well as between the iron core and the clamping piece is reduced, and buffering force between the iron core and the base as well as between the iron core and the clamping piece is enhanced, so that the transformer has the advantage that shock-proofing and shock-absorbing capabilities are improved to greatly reduce noise in the working process.
