Purpose:
Shielded signal cables (shielded signal wires) are suitable for connecting power electrical appliances, instruments, and telecommunications equipment control, monitoring circuits, and protection lines with rated voltages of U0/U 450/750V and below. They are mainly used to prevent electromagnetic wave interference and in places where shielding is required.
2、 Product standards
GB9330-1998
3、 Usage conditions
The long-term allowable working temperature for cable insulation is 70 ℃, and the allowable bending radius for cable laying and installation is:
1. The cable without armor layer should not be less than 6 times the outer diameter of the cable.
2. Cables with armor or copper tape shielding structures should not be less than 12 times the outer diameter of the cable.
3. Flexible cables with shielding layer structures should be less than 6 times the outer diameter of the cable.
