| Abstract: | A vacuum pressure impregnation(VPI) process for making 660MW stator bars was developed based on the main insulation property test of sample bars made by VPI technique.The electrical and mechanical properties of the main insulation were analyzed and compared with those of resin-rich moulding main insulation that conforms to standard JB/T 56082.The results indicate that the products made by VPI process meet the requirements for best quality insulations stipulated in the industry standard. |
