Z-Shield® (2L)

Drawing No. ZT93-04-007

Dual Wall Fire-Retardant Polyurethane Jacket with Z-3250-CN EMI Shield

Z-Shield® (2L) consists of two layers of fire-retardant Polyurethane film encapsulating a Z-3250-CN EMI shield cloth, and utilizes a double adhesive closure. The dual layer of Polyurethane film creates a finished jacket that has an inner dielectric spacer and will meet UL224, VW-1 flammability requirements.

Z-Shield® (2L) provides outstanding electromagnetic shielding of wires and cable bundles. It is highly flexible, and provides good dielectric strength and mechanical protection of the cable. The product can be configured for Round; Flat or Rectangular cable shapes and is available with or without a drain wire.

This product has an operational temperature range of -45° to 80°C (-49° to 176°F).
