摘要： An electrical transformer includes a coil pack including windings, and spacers axially spacing turns of the windings from one another and being formed of a thermoplastic material. Sticks couple and position the spacers. The coil pack has high resistivity to creep and permits temperature rise without degradation of transformer insulation, providing for extended service life and unique methods of transformer system upgrade.
