Arctic Grade Instrumentation Cables
Arctic Grade Instrumentation Cables
-40℃ Signal Stability
Key Features
Low Temperature Flexibility
Utilizes specialty silicone rubber and modified polyolefin insulation to maintain superior flexibility from -40°C down to -60°C.
Achieves a minimum bending radius as low as 3x cable OD (dynamic conditions) and withstands over 5 million cold-bending cycles.
Low Attenuation Signal Transmission
At -40°C, signal attenuation is ≤0.5dB/100m (1kHz), with impedance fluctuation controlled within ±5Ω.
Guarantees low-distortion, low-latency transmission for both analog and digital signals in ultra-low temperature environments.
Exceptional Weatherability
Engineered to withstand over 1000 repeated freeze-thaw cycles from -40°C to -60°C with no performance degradation.
Features a jacket with ultra-low water absorption (≤0.1%), effectively preventing insulation failure caused by moisture ingress from melting ice and snow.
High Mechanical Strength
Combines ultra-fine stranded conductors with a cold-resistant strengthening structure to ensure tensile strength ranging from 100 to 2000KG at low temperatures and tear strength ≥25N/mm².
Comprehensive Environmental Adaptability
Beyond ultra-low temperature performance, it exhibits excellent resistance to aging, salt spray (tested to ≥2000 hours), oil, and UV radiation, making it ideal for complex and harsh environments.
Specifications
