Description

Spira-Shield provides high permeability magnetic shielding and physical protection for any ROMEX® electrical wiring. Made of .010″ thick Magnetic Shielding Alloy. Slips over standard wiring to provide that peace of mind when it must be near electromagnetically active sources. Also reduces interference in stereo and telephone lines. Ground it for the added benefit of E-Field shielding.

Shielding performance depends on many factors, including field strength and tube diameter.
Here are some examples based on DC field, perpendicular to the THIN tube:
Field outside of tube Field inside tube
5 Gauss…………………… 1 mG
1 Gauss…………………… 0.2 mG
250 mG…………………… less than 0.2 mG

For clarification: this item protects the cable inside the shield from magnetic fields originating outside the shield.
Thin is 3/8″ ID and 1/2″ OD. Wide is 3/4″ ID and 7/8″ OD. Priced per 10 foot length.
