Supra-Shield: Superior Shielding from Alpha Wire

Posted on Wednesday, July 1, 2015 by Kimberly Versaw

Simply put, Supra-Shield® is Alpha Wire’s exclusive premium foil/braid shielding.  Supra-Shield cables combine a triple-layer aluminum/polyester/aluminum foil with a 25% overlap and in contact with a stranded tinned copper drain wire equal in size to the insulated cable conductors.  Additionally, a tinned copper braid shield is then applied overall with 70% coverage.  

Supra-Shield offers exceptional EMI performance and flexibility to protect against noise and maintain overall system integrity.  The combination of foil and braid offers better shielding effectiveness than either approach alone against both low- and high-frequency noise.

Products from the Alpha Wire portfolio that includes the Supra-Shield option include:  EcoCable, EcoFlex, EcoCable Mini, Xtra-Guard 1, Xtra-Guard 2, Xtra-Guard 3, Xtra-Guard 4, Xtra-Guard 5, Xtra-Guard Flex, and Xtra-Guard Industrial Ethernet
