This high-alumina ceramic bobbin heater core is a support and insulation component for resistance heating wires in industrial furnace assemblies. Made from high-alumina ceramic, it is used in industrial furnaces, radiant tube heaters, kilns, drying ovens, and heat-treatment equipment. Its cylindrical structure keeps heating wires evenly positioned and separated from surrounding metal parts, helping reduce wire movement, electrical contact, and structural instability during repeated high-temperature cycles.
Material System
Material: Alumina ceramic
Function: Supports and insulates resistance heating wires
Structure: Cylindrical core with custom holes or grooves
Customization: Length, diameter, hole layout, and wire path
Ceramic bobbin heater cores are mainly used in high-temperature electric heating systems where resistance wires need stable ceramic support and reliable insulation. They are suitable for furnace environments that require repeated heating cycles, stable wire arrangement, and long service performance.
Stable Wire Positioning: The bobbin structure keeps resistance heating wires evenly arranged and properly separated.
