摘要（英）：

The invention provides a high-thermal conductivity epoxy resin composition and a preparation method thereof. The composition includes epoxy resin, a curing agent, an accelerator and filler. In percentage by mass, the filler is 60%-70% of the composition. The thermal conductivity of the epoxy resin composition provided by the invention is within 1.0-2.0W/(m.K), so that the composition can increase the thermal conductivity substantially and remarkably reduce the operating temperature of a saturable reactor. The epoxy resin composition provided by the invention has good high thermal conductivity, an excellent crack resistance property, a good electrical insulation property and a good flame retardant property. The epoxy resin composition provided by the invention can be used as an insulated encapsulating material for direct current converter valve saturable reactors. The technical solution provided by the invention has the advantages of simple structure, easy operation, high practicability and low production cost.
