Abstract
Embodiments of the present disclosure relate to a power equipment and method for providing the same. Embodiments of the present disclosure relate to a power equipment. The power equipment includes a high voltage part, a low voltage part, and an insulation oil adapted to impregnate the high voltage part and insulate the high voltage part from the low voltage part. The insulation oil is partially filled with polymer particles with a lower thermal expansion coefficient than the insulation oil. According to embodiments of the present disclosure, the degree of expansion of the insulation medium can be reduced in a cost-effective way
