Insulation Insulation is non-conductive material used to prevent leakage of electric current from a conductor. There are several classes of insulation in use for generator construction, each recognized for a maximum continuous-duty temperature.
绝缘 绝缘体就是非导电材料，用来防止导体中电流的泄露。按最高持续耐热度划分，发电设备中使用的绝缘体有多种等级。
