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.
