  • Ceramic tube insulator bead high temperature resisting insulating alumina zirconia insulators


    The ceramic tube insulators are available in stock. The tube insulators are constructed of zirconia ceramics , alumina ceramic and other advance ceramics that has superior gas and vacuum tightness and excellent insulating properties even at elevated temperatures.
     

    Ceramic dome head interlocking insulating beads for flexible electrical insulation on wires
    Steatite material has excellent electrical resistance at high temperatures, good mechanical strength and a very low dielectric loss factor.
    Bead size outside diameter 5.0mm, inside diameter 2.0mm, overall height 6.0mm, height to shoulder 4.8

    Notes:
    Wire-to-ceramic coaxial clearance does affect overall flexibility; therefore, as wire size increases, flexibility decreases.
     
    The electrical and thermal ratings specified are of safe operating limits determined by various factors including material properties, mechanical design, and the intended operating environment. All electrical ratings are based on operation with one side in dry atmosphere and the other side in vacuum of less than 1 x 10-4 Torr. All VacuCAD files as well as any dimensions shown or listed in our ordering tables do not include manufacturing tolerances and are provided for reference only.
     
    Unless otherwise noted they can also be supplied in longer lengths . We can also custom cut shorter lengths to your specifications. Contact us with your specific requirements.
     
    Other sizes available on request

    We produce and sale ceramic inslating bead with multi sizes for industry applications. and also offer custom service for our customers. for more details like diameter, instocks, price, delivery time, price etc, please contact us soon, our ceramic engineer feedback within i hours. thanks
