For complete specifications and availability, visit www.alphawire.com. 542 Alpha Aluminum/Polyester Foil Shielding Lightweight shielding Low cost Ease of termination with use of stranded tinned copper drain wire High-frequency interference 100% coverage over the core of cable conductors Alpha aluminum/polyester foil shielding consists of an aluminum polyester tape, foil side facing inward, with a 25% overlap and in contact with a stranded, tinned copper drain wire equal in size to insulated cable conductors. Alpha Supra-Shield (Foil/Braid) Shielding Ease of termination with use of stranded tinned copper drain wire High-frequency interference High physical strength Alpha Supra-Shield (foil/braid) shielding system consists of a unique triple- laminate tape. An aluminum/polyester/aluminum tape is bonded in one layer with a 25% overlap and in contact with a stranded tinned copper drain wire equal in size to the insulated cable conductors. A 70% coverage tinned copper braid shield is applied overall. Xtra-Guard Flexible Cable Braid Shielding EMI/RFI resistance in power, control and data applications Continuous shield continuity in flexing applications High physical strength Xtra-Guard flexible cables have specific shielding requirements resulting from the stresses of motion and flexing. Where foil shields will tear and lose continuity, Xtra-Guard flexible cables use a flexible, 85% coverage, tinned copper braid with a double jacket isolating the shield from the cable's inner core.
