Hubei plant and Guangdong plant:


DMD is just one of many insulation materials used in electrical applications, and its properties make it well-suited for certain applications compared to other materials. Here are some comparisons with other insulation materials:

DMD vs. Nomex: Nomex is another popular insulation material used in transformers. It is a synthetic material made from aramid fibers and is known for its high-temperature resistance. While Nomex is better suited for high-temperature applications, DMD typically has better mechanical properties and is less expensive.

DMD vs. Kapton: Kapton is a polyimide film that is also used for insulation in electrical applications. Kapton has excellent thermal stability and is often used in high-temperature applications, but it is more expensive than DMD and not as good at preventing electrical arcing.

DMD vs. Epoxy: Epoxy is a common insulation material used in electrical applications. It is a thermosetting polymer that is applied as a coating or adhesive. While epoxy has excellent adhesion and chemical resistance, it is not as good at preventing electrical arcing as DMD.

DMD vs. Mica: Mica is a natural mineral that is often used as an insulation material in electrical applications. While mica has excellent electrical properties, it is less flexible and more prone to cracking than DMD, making it less suitable for applications that require a lot of bending or flexing.

Overall, the choice of insulation material depends on the specific application requirements, including temperature, voltage, mechanical stress, and cost. DMD is a popular choice for transformer insulation due to its combination of electrical and mechanical properties and its cost-effectiveness.
