Zirconia Roller For Coil Drawing

Zirconia ceramic roller features superior electrical insulation and dielectric properties, which can effectively isolate electromagnetic coils, prevent leakage and short circuits, and ensure stable and safe operation of electromagnetic equipment. Different from conventional ceramic parts, zirconia roller owns high fracture toughness and bending strength, resisting cracking, deformation and abrasion during long-term high-frequency vibration and mechanical operation. It can continuously work stably at temperatures up to 1600°C, with outstanding thermal shock resistance, free from aging and melting under extreme high-temperature conditions.

In addition, this roller presents excellent chemical inertness, resisting corrosion from acid, alkali, oil and industrial gas, maintaining stable structural and electrical performance in humid and corrosive environments. With low thermal conductivity, it can effectively isolate heat transfer and protect internal coil structures from high-temperature burnout. Fine dimensional accuracy and smooth inner and outer surfaces reduce coil friction damage and improve assembly efficiency.

Widely applicable in industrial furnaces, electromagnetic heating equipment, high-frequency transformers and precision electrical appliances, our zirconia ceramic coil tubes support customized sizes and structures. With strict dimensional tolerance control and stable batch quality, they provide durable, high-reliability insulation protection solutions for high-temperature electromagnetic industrial equipment.
