In cutting-edge fields such as semiconductor manufacturing, particle accelerators, and quantum technology, ultra-high vacuum (UHV) environments of 10⁻⁷ mbar to 10⁻¹² mbar place extremely stringent requirements on the stability and reliability of signal and power transmission. Ordinary cables are prone to problems such as outgassing, insulation failure, and performance drift in such extreme environments, becoming a key bottleneck for technological upgrades and breakthroughs in related fields.
TST CABLE has launched a new series of ultra-high vacuum (UHV) wires and cables, supported by core extruded polyimide (PI) technology. It breaks through traditional limitations in all aspects, from material selection to process design, and can be perfectly adapted to various extreme vacuum application scenarios, providing stable and reliable all-weather protection for signal and power transmission in cutting-edge high-end technology fields.
Hardcore performance: Unlocking the transmission secrets of extreme environments
TST CABLE UHV series cables have made comprehensive breakthroughs in traditional technology limitations, with all performance indicators reaching the top level in the industry.
01 Ultimate Vacuum Compatibility
Passing rigorous testing according to ASTM E595, the total mass loss (TML) is <1%, the volatile condensable matter (CVCM) is <0.1%, and it operates stably in ultra-high vacuum environments from 10⁻⁷ mbar to 10⁻¹² mbar without any excess gas venting that contaminates the equipment.
02 Wide-range temperature sensing adaptation
With an operating temperature range of 4K (-269℃, liquid helium environment) to 300℃, it can maintain stable performance in both cryogenic quantum experiments and high-temperature vacuum furnace scenarios, and the insulation and sheath will not crack or fail.
03 Strong radiation resistance
It can withstand a radiation dose of 10⁹Rad (10⁷Gy). In strong radiation environments such as particle accelerators and nuclear research, the surface of the insulation layer does not crack, and the tensile strength change rate is ≤±15%, ensuring long-term reliable transmission.
04 Pure Material Design
It contains no organic additives, plasticizers, or ordinary pigments, is non-magnetic, and has extremely low permeability, thus avoiding electromagnetic interference to precision instruments and ensuring the accuracy of experimental data and transmitted signals.
05 Excellent mechanical properties
The minimum bending radius for long-term use at room temperature is only 7-7.5 times the outer diameter of the wire, and it can withstand ≥20,000 scratches, making it suitable for complex wiring and frequent movement requirements inside vacuum chambers.
