| 摘要 |
The present invention refers to an interlaceable impregnation dielectric composition, comprising a polyol polydiene, a polyisocyanate and a chemically inert liquid filler, characterized in that a sufficient amount of said liquid filler is used in order to maintain a viscosity lower than 50 mPa s at impregnation temperature, during a period of at least equal a day, and in order to obtain a batch at 20 degree C and at 50 z, after interlacing has been completed, of less than 0.02. The present invention also refers to a process for the preparation of said composition.
