二次绕组及铁芯均浇注在聚脂树脂内。
The secondary windings and iron core are insulated by epoxy resin.
使用时二次绕组不能短路及超负荷运行。
In using, the secondary winding can not be short-circuited or operating over-load.
电压互感器二次绕组不得短路，否则互感器将被烧毁。
There should be no short circuit at the secondary winding for a voltage transformer, or the voltage transformer would be damaged.
