A THERMAL CONDUCTIVE COMPOUND FOR SEALING A POWER TRANSFORMER ASSEMBLY AND A POWER TRANSFORMER ASSEMBLY

摘要

A thermal conductive compound for sealing a power transformer assembly and a power transformer assembly are disclosed. The thermal conductive compound comprises a silicone resin and fillers. The fillers at least include a first filler, or main filler, and a second filler. The first filler is a natural mineral filler including finely divided quartz, quartzite, marble, sand and/or calcium carbonate. The second filler includes a given amount of aluminium hydroxide lowering linear expansion coefficient and increasing the thermal conductivity of said silicone resin.
