Product DescriptionThe power feedthrough with a CF CF-type vacuum flanged fitting. It is an electrical feedthrough and conveys high-voltage, high-amperage power into high-vacuum environments for operating heating coils in sputtering, coating, and other demanding material evaporation applications or experiments.Feedthroughs (also known as vacuum feedthroughs) come in various forms to transfer electrical currents, signals, fluids, gases, or mechanical movements from the outside (air side) to the inside (vacuum side) of a vacuum chamber, thereby connecting equipment within the chamber. The entry point for the feedthrough must be vacuum-sealed via a suitable through hole. The feedthrough can be weldable (weld-on) or connected with a CF, KF, or ISO vacuum flange to the vacuum chamber.Typical Applications* Industrial Heaters* Terminating Power Cables* Isolating Other High Heat or Power SourcesGeneral Specifications:Working VoltageUp to 100KVCurrent RatingUp to 1000AVacuum RatingBetter than 1×10-9 mbar litre sec-1Operating Temperature-270°C to 450°CFlange MoutingCFAlumina Ceramic PropertiesPropertiesUnitsAlumina CeramicPuritywt%95%99%99.8%Volume Densityg/cm33.653.8≥3.89Water Absorption%000Crystal Size(Grain Size)μm4-54-54-5Vickers Hardness, HV1.0Gpa141600≥15Flexural StrengthMpa300310≥300Coefficient of LinearExpansion20-500℃1x10-6 mm/℃6.5-7.56.5-7.56.5~7.520-800℃6.5-8.06.5-8.06.5~8.0Thermal ConductivityW/m·K( 20℃)2025≥20.9Specific Heat CapacityKJ/(kg·K)≥0.8≥0.8≥0.8Dielectric StrengthKV/mm≥1215*106≥12Volume ResistivityΩ·cm 20℃≥1014≥1014≥1014Ω·cm 300℃≥1011≥1011≥1011Ω·cm 500℃≥109≥109≥109Dielectric Constant1MHz99-109-10Tangent of Dielectric Loss1MHz≤4x10-4≤2x10-4≤3x10-4Surface Roughnessμm0.4 After Machine0.1-0.4 After Machine0.1-0.4 After MachineMax Working Temperature℃160016001650
