There are several parameters for computer cables:
1. Rated voltage of the product (U0/U): 300/500V
2. The long-term working temperature is 70 ℃
3. The ambient temperature during installation shall not be lower than: -40 ℃ for fixed installation, -15 ℃ for non fixed installation
4. Small bending radius: For unarmored cables, it should be less than 6 times the outer diameter of the cable, while for armored cables, it should be no less than 12 times the outer diameter of the cable
5. The insulation resistance should not be less than 2500M Ω· Km after stable charging for 1 minute using a DC 500V voltage test at 20 ℃
6. There should be no open circuit between the paired shields and between the paired shields and the total shield
7. The core and shield of the cable should withstand a 50Hz, 2000V AC voltage test for 5 minutes without breakdown
