About DMC Insulator

A DMC Insulator is an electrical insulator made from a Dough Molding Compound (DMC), which is a type of thermosetting composite material. It is used to provide electrical insulation and mechanical support in electrical systems by separating conductors from other components. DMC insulators are known for their high mechanical strength, excellent electrical properties, and resistance to heat and chemicals. 

Characteristics of Our DMC Insulators

• Elevated dielectric strength
