TRANSFORMER SPACERS

摘要

An insulation system for an electrical power transformer that includes at least a non- cellulose based axial spacer. The axial spacer may include a pair of spacer arms that extend from a base wall of the axial spacer. Additionally, the spacer arms and the base wall may generally define a hollow inner region of the axial spacer, thereby reducing the volume of the axial spacer. According to certain embodiments, the spacer may include lips that are adapted to lockingly engage a radial spacer. Additionally, at least a portion of the axial spacer and the radial spacer may be constructed from a thermoplastic and/or a thermoset plastic. Further, according to certain embodiments, another portion of the axial spacer, such as, for example, the lips, may be formed from a flexible thermoplastic elastomer or a thermoset elastomer so as to provide the axial spacer with a combination of both flexibility and stiffness.
