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
• Fire-resistant building materials
• Outstanding tracking resistance
• Minimal water absorption
• Operation without the need for maintenance
• Appropriate for high-voltage use.
• Durable molded coating guaranteeing extended lifespan

DMC Insulators are used in:

• Electrical Control Panels – Serve as support and insulating elements in MCC, PCC, APFC, and automation panels.
• Switchgear & Power Distribution Boards – Guarantees secure separation of conductive components in isolators, circuit breakers, and distribution equipment.
• Busbar Support Systems – Delivers mechanical support and avoids electrical flashover in high-current busbar configurations.
• Transformers & Substation Gear – Employed in spacers, terminal plates, connector bases, and various insulating components.
• Circuit Breakers, Fuse Gear &Disconnectors – Improves insulation in high-pressure switching equipment.
• Industrial Machines & Original Equipment Manufacturer Products – Perfect for devices that need insulation components that are resistant to vibration and stable in heat.
• Railway Electrical Systems – Utilized in control units, traction equipment, and panel boards because of its flame-resistant characteristics.
