Shielded signal cables (shielded signal cables) are suitable for connecting power appliances, instruments, and telecommunications equipment with rated voltages up to and including U0/U450/750V, control circuits, monitoring circuits, and protection circuits. They are primarily used in applications requiring shielding to protect against electromagnetic interference.

II. Shielded Signal Cable Product Standard
GB9330-1998
III. Shielded Signal Cable Usage Conditions
The long-term allowable operating temperature of the cable conductor is 70°C. The allowable bending radius for cable installation is as follows:
1. For cables without armor, the allowable bending radius should be no less than 6 times the cable's outer diameter.
2. For cables with armor or copper tape shielding, the allowable bending radius should be no less than 12 times the cable's outer diameter.
3. For flexible cables with shielding structures, the shielding layer should be less than 6 times the outer diameter of the cable.
