There are two shielding methods for wires and cables: winding and braiding.
1. Winding Shielding
1. Winding is inferior to braiding in terms of shielding effectiveness.
2. Its shielding effect is directional.
3. Its shielding properties change when bent.
4. However, it offers advantages such as a small outer diameter, flexible wire, and relatively low price.
5. It is suitable for low-frequency shielding.
2. Braided Shielding
Wire and cable braiding, similar to diagonal wrapping, primarily serves as a shield within the wire, protecting it from external electric and magnetic fields.
It improves the wire's interference resistance and has the following advantages compared to diagonal wrapping and aluminum foil:
1. The shielding is non-directional.
2. It has excellent high-frequency shielding properties, making it suitable for high-frequency shielding.
3. Through multi-layer shielding, the shielding effectiveness can reach 100%.
4. The shielding properties remain unchanged when bent.
