Effect:
The main function is to separate the high and low voltage windings, prevent electrical breakdown, and provide reliable mechanical support for the windings to ensure that they will not deform or be damaged in the event of short circuits or other abnormal situations.

Product Features：
This type of composite enclosure is usually made of multiple layers of polyester film pre impregnated with epoxy resin, such as the common DMD (i.e. polyester fiber film epoxy resin glass fiber cloth) structure.
Excellent electrical insulation: can effectively block current, withstand high voltage, and ensure the safe operation of transformers.
High mechanical strength: The structure is sturdy and can withstand the huge electromagnetic force generated when the winding is short circuited, providing stable support.
Good heat resistance: Common temperature resistance levels include B-grade (130 ℃) and F-grade (155 ℃), which can maintain stable performance in high temperature environments.
Chemical corrosion resistance: It has good resistance to chemicals such as acids and alkalis, and can adapt to complex operating environments.
