Our Ultra-Thin Polyimide (PI) Insulated Cables is a premium specialized cable engineered exclusively for the extreme operating conditions of nuclear fusion devices, primarily tokamak systems. As the critical "lifeline" of fusion magnet systems, it delivers stable power transmission, precision control signal delivery, and compatibility with cooling media circuits, built with advanced superconducting materials and proprietary insulation & shielding structures. This tokamak cable withstands intense ionizing radiation, ultra-wide temperature swings, and extreme magnetic fields, fully aligned with ITER project standards. It is the ideal solution for nuclear research institutions, commercial fusion power plant developers, and fusion project engineering teams.
Our radiation-resistant fusion cable delivers industry-leading ionizing radiation tolerance up to 10⁹ rad. After 3000 hours of radiation testing, it maintains insulation resistance ≥80MΩ, signal attenuation ≤3%, and mechanical strength loss below 8%, far exceeding nuclear industry benchmarks to eliminate unplanned downtime.
This high-temperature nuclear fusion cable supports a long-term working range of -196℃ to +350℃, with short-term resistance up to 400℃ (≤20 minutes of continuous operation). Even under alternating ultra-low temperature cooling and ultra-high temperature reaction cycles, performance fluctuation is ≤4%, fully meeting fusion operation thermal demands.
Fabricated with 99.999% high-purity oxygen-free copper and low-loss insulation, the cable has a DC resistance ≤0.011Ω/mm² at 20℃. For high-frequency control signals, transmission loss is ≤0.015dB/m, minimizing distortion to ensure accurate, real-time power and signal delivery for critical fusion systems.
With a multi-layer reinforced structure, the cable has tensile strength ≥1800N/mm² and a bending radius ≤6× the cable diameter, with exceptional wear, impact, and fatigue resistance. After 5000 hours of accelerated aging testing, it delivers a ≥25-year service life, matching fusion project cycles and reducing long-term maintenance costs.
