Foil shielded wire and braided shield<\/p>

Foil shielded cable and braided shielded cable are two of the most common types of shielded cables used in industrial applications. The foil shielded cable shield contains a thin sheet of copper or aluminum. This "foil" is usually bonded to a polyester carrier to increase the strength of the cable. Also known as a "tape" shield, this type of shielded cable provides 100% of protection to the conductor wires they are wrapped around. EMI from the environment cannot penetrate. However, due to the very fragile foil within the cable, these cables are very difficult to work with, especially when using connectors. More often than not, a drain wire will be used instead of trying to completely ground the cable shield.<\/p>

The second method used to shield cable is braiding. Braided shielded cable uses a mesh of braided copper wires. Braided shields have less coverage than foil shields, but are more durable. The braid creates a low-resistance ground path that is much less difficult to terminate when connectors are applied. Braided shields typically provide 70% to 95% of EMI protection, depending on how tightly the braid is. Braided shields are more effective than foil shields because copper has a higher conductivity than aluminum, and they are not as susceptible to internal damage. Braided shielded wires are heavier and more expensive than ribbon shielded wires because they are more durable and perform better.<\/p>
