What is the difference between flame-retardant insulated PVC electrical sleeve and PVC conduit?

阻燃绝缘PVC材料里面添加了阻燃剂，在高温时，阻燃剂会分解，部分分解物为水，可有效阻止燃烧。普通PVC线管无此功能。

The flame retardant is added to the flame retardant insulation PVC material. At high temperature, the flame retardant will decompose, and part of the decomposition is water, which can effectively prevent combustion. Ordinary PVC conduit does not have this function.

用处区别：difference

阻燃绝缘PVC用在保护电线套管，对阻燃（防火）绝缘（电性能/电击穿）有要求。

PVC套管可以用在很多地方，常用排水管道等等。

Flame retardant insulation PVC is used to protect wire sleeves, and has requirements for flame retardant (fire resistant) insulation (electrical performance/electrical breakdown).

PVC casing can be used in many places, such as common drainage pipes.
