Goodfellow Ceramic Bead Ceramic White +1200°C


This white ceramic bead from Goodfellow offers a practical solution for extremely high-temperature electrical insulation of wires. It has a bore size of 2.5 mm and is supplied in quantities sufficient to cover 3.5 m of wire.

Thanks to its steatite Ker 220 construction, this bead has high electrical resistance. It can withstand temperatures up to +1200°C and is abrasion resistant, so it's particularly useful when you're running wires close to a heatsink. An interlocking fish-spine design means you can easily link multiple beads together for flexible insulation around wires.

The mechanical strength, electrical resistance and insulation properties of this ceramic bead make it suitable for industrial wiring applications that require high voltage, high frequency or high temperature. It's commonly found in insulation for electrodes and curved wires as well as in 3D printers and cartridge heaters.
