Our Stainless Steel Low Temperature Cable (also called Cryogenic Stainless Steel Cable) is a professional transmission cable specially engineered for extreme ultra-low temperature environments. Featuring a robust 304 stainless steel sheath, high-purity conductor, and specialized low-temperature insulation, this cable delivers stable power and signal transmission at -269℃ to -100℃. It is the trusted solution for cryogenic equipment manufacturers, aerospace engineering teams, scientific research institutions, medical device producers, and special industrial operators requiring reliable performance in extreme cold conditions.
Designed exclusively for extreme cryogenic environments, our Ultra Low Temperature Cable maintains stable performance across -269℃ to -100℃ (liquid helium to liquid nitrogen temperature range). After 1000 hours of continuous low-temperature testing, its tensile strength retention rate remains ≥95% of the standard value, with no brittleness or insulation cracking, ensuring uninterrupted reliable transmission in cryogenic scenarios.
This Low Temperature Resistant Stainless Steel Cable adopts a high-grade 304 stainless steel sheath, delivering strong corrosion resistance to acids, alkalis, and low-temperature media. With a corrosion rate ≤0.01mm/a in harsh environments and passing a 2000-hour salt spray test, it effectively protects internal conductors and insulation layers from environmental damage.
Equipped with high-purity oxygen-free copper conductor (purity ≥99.99%), our Cryogenic Cable features a DC resistance ≤0.017Ω/mm² at 20℃. Even at -200℃, signal attenuation is ≤0.03dB/m, ensuring distortion-free, uninterrupted stable transmission of electrical energy and sensitive signals in extreme cold conditions.
The cable maintains outstanding low-temperature toughness, with an elongation at break ≥300% at -269℃. It can withstand 500 cycles of low-temperature bending tests without damage, and its minimum bending radius is ≤5× cable outer diameter, meeting the laying requirements of narrow cryogenic equipment and complex pipeline systems.

Our Stainless Steel Low Temperature Cable is widely deployed across industries requiring reliable transmission in ultra-low temperature conditions. Core applications include cryogenic scientific research laboratories (for liquid helium/liquid nitrogen storage equipment and cryogenic detectors), aerospace and satellite systems (for rocket cryogenic fuel systems and space probes), medical cryogenic equipment (MRI machines and cryogenic treatment instruments), cryogenic refrigeration equipment and LNG processing systems, as well as low-temperature superconducting and cryogenic metallurgy industrial projects. It is tailored to meet the strict demands of research institutions, medical device manufacturers, aerospace engineering teams, and special industrial operators.
We recognize that cryogenic projects have unique and strict transmission requirements, so we offer fully customized solutions for our Ultra Low Temperature Cable to match your specific operating conditions. Customization options include custom conductor cross-sections and core counts for specific power and signal transmission needs, custom stainless steel sheath thickness for enhanced corrosion or pressure resistance, optimized insulation materials for extreme cryogenic scenarios, and custom shielding structures for sensitive signal transmission in high-interference environments. Our R&D and engineering team works closely with cryogenic equipment manufacturers, research institutions, and industrial engineering teams to deliver tailored cable solutions that meet your project’s precise specifications.
As a professional special cable manufacturer, we implement strict full-process quality control for our Cryogenic Stainless Steel Cable. All production processes comply with GB/T 12972.7-2008 standard, with a one-time qualification rate ≥99.9%. Each batch of products undergoes 10 strict performance inspections, including ultra-low temperature resistance, corrosion resistance, electrical transmission, and mechanical toughness tests, with complete test reports provided to ensure product reliability and consistency for our industrial and scientific users.
We can provide cable samples for your performance testing. For standard low-value products, samples are available free of charge; for high-value custom-engineered cables, sample fees will apply, with specific terms negotiable with our sales team.
For standard mature products, delivery is completed within 1 month. For custom-designed special low-temperature cables, the delivery cycle will be confirmed based on your specific customization requirements.
Yes, our Stainless Steel Low Temperature Cable is designed to operate stably at -269℃ (liquid helium temperature), with no brittleness or performance degradation after long-term immersion in liquid helium.
