绝缘系统请参考IEC 60085, 主要是以构成材料的温度来分类。
INSULATION SYSTEM – A unique intimate combination of two or more insulating materials used in
electrical equipment. One example of this is the combination of magnet wire, ground insulation, varnish, lead wire insulations, and outer wrapping of a coil. These intimate combinations are evaluated as
unique groups. When multiple groups exist, either within a given insulation system or a different
insulation system, components of one unique group shall not be added to another unique group.
However, more than one group is able to be used within a single device when at least a 3.05 mm
(0.125 inch) air space is used to separate them. Any material or component existing outside the outer
wrap of the device or not in contact with the windings is not determined to be part of the insulation
system.
绝缘系统是个很广义的概念，看你具体考察的是那个部分，比如有电机绝缘、变压器绝缘、电缆绝缘系统等等太多了，你看下IEC的标准吧～ |
