Fenhar utilizes a variety of high-quality materials for switchgear insulation, each offering specific performance benefits:

1. Mica M: For high voltage and high-temperature insulation, offering exceptional mechanical, electrical, and thermal characteristics.
2. NEMA GPO-3: Known for its excellent track, arc, and flame resistance, commonly used in transit applications.
3. NEMA G-9: A woven glass cloth laminate with a melamine resin binder, offering high mechanical strength and flame arc resistance.
4. Sheet Molding Compound (SMC): A polymeric composite with strong mechanical and electrical insulating properties, ideal for supporting live electrical components.
5. NEMA FR4: A glass fabric-reinforced laminate bonded with flame-resistant epoxy resin, perfect for elevated temperature environments up to 130°C.
6. Mylar: Made from electrical grade polyester film, often used in combination with cotton rag paper for laminated electrical insulation.

We offer flexible and fast customization for switchgear components, ensuring materials meet specific design requirements with precision and speed.

Fenhar materials deliver long-lasting performance, providing robust electrical insulation that withstands high temperatures, mechanical stress, and environmental conditions.
