Title:

POWER EQUIPMENT AND ASSOCIATED MANUFACTURING METHOD

Document Type and Number:

WIPO Patent Application WO/2021/168604

Kind Code:

A1

Abstract:

A power equipment and method for providing the same are disclosed. The power equipment comprises a high voltage part (14, 24, 34), a low voltage part (16, 26, 36), and an insulation oil adapted to impregnate the high voltage part (14, 24, 34) and insulate the high voltage part (14, 24, 34) from the low voltage part (16, 26, 36). The insulation oil is partially filled with polymer particles (5) with a lower thermal expansion coefficient than the insulation oil. The degree of expansion of the insulation medium can be reduced in a cost-effective way.
