Usage:
Shielded signal cables (shielded signal wires) are suitable for power equipment rated voltage U0/U 450/750V and below, as well as for connecting lines in control, monitoring circuits, and protective lines of instruments, meters, and telecommunications equipment. They are mainly used to prevent electromagnetic wave interference in places where shielding is required.
Section 2: Product Standards
GB9330-1998 
III. Terms of Use
The long-term allowable operating temperature for the cable conductor is 70°C, and the installation allows for a bending radius for the cable laying.
Unarmored cables should not be less than 6 times the diameter of the cable's outer circumference.
2. Cables with armor or copper tape shielding should have a diameter not less than 12 times the cable's outer diameter.
3. The flexible cable with a shielding layer structure should be less than 6 times the cable's outer diameter.
