Rated Voltage: U/U: 300/350V.
Minimum Bend Radius: For unarmored cables, the minimum bend radius should be no less than 10 times the cable's outer diameter; for armored cables, the minimum bend radius should be no less than 12 times the cable's outer diameter. 2. Intrinsically Safe Circuits and Computer Cables
Implementation Standard: Q/AJTZD004.3-2001.
Application: This cable features low capacitance and inductance, excellent shielding and anti-interference properties, and therefore superior explosion-proof performance compared to general computer and control cables. It is suitable for use as a transmission line in distributed control systems and automated detection and control circuits where explosion-proof requirements are required. Usage Characteristics: Rated voltage: U/U: 300/500V. Maximum operating temperature: Polyethylene insulation not exceeding 70°C, cross-linked polyethylene insulation not exceeding 90°C, and irradiated cross-linked polyethylene insulation not exceeding 105°C. Minimum ambient temperature: -40°C for fixed installations, -15°C for non-fixed installations. Minimum bending radius: For unarmored cables, the minimum bending radius should be no less than 6 times the cable's outer diameter; for armored cables, the minimum bending radius should be no less than 12 times the cable's outer diameter.
Note: Flame-retardant cables are designated with "ZR" before the model number, and fire-resistant cables are designated with "NH" before the model number. 3. Low-Smoke, Halogen-Free, Flame-Retardant Computer Cable
Implementation Standard: Q/AJTZD004.4-2001.
Application: This cable features low capacitance and inductance, excellent shielding and anti-interference properties, and therefore offers superior explosion-proof performance compared to standard computer cables and control cables.
