Shielding Conduit for Military Installations

SHIELD-FLEX shields sensitive equipment and circuits from EMI/RFI emissions, both ingress and egress. But shielded conduit doesn't just keep interference out; it also keeps emissions in, which is vital to meeting European CE standards - an important issue for OEMs.

Connector assemblies include a grounding ferrule that contacts the conduit's internal metallic material with the connector body, producing a direct shield-to-drain (ground) simply by tightening the connector. It's flexibility and simple assembly means it takes less time to install. It uses off-the-shelf (OTS) connectors that are less expensive than high-end, mil spec shielded conduit that require costly custom fittings.

Known applications with EMI/RFI concerns:

· High Frequency cables and or Coils

· Variable Frequency Drives in close proximity to other controls or devices

· Where communications are extremely sensitive and need to be protected from intrusion by unwanted parties.

· In applications where large pumps, motors, and or generators are located in or around sensitive electronic equipment.

· Where TEMPEST, MIL STD 461E, CE, or UL standards require a low amount of electromagnetic emission from the device and or project.

· Military Radios and communications equipment

· Military Shelters

· Navy and Commercial vessels

· Military Ground Vehicles

· Wind Energy systems

· Wireless Communication Towers

· Mining equipment and for power cables within mines

All versions can be manufactured with halogen-free jacketing material, using a HF prefix.

· Good Shielding: Type SLA®, UL Listed, is a flexible steel conduit with a galvanized steel core, over which a tinned copper shielding braid is applied. The outer jacket is flexible PVC with a temperature rating of -30°C to 80°C Dry/60C Wet/70C Oil while the braid offers a minimum of 90% shielding coverage.

· Better Shielding: Type EMS® offers a better shielding effectiveness than Type SLA with a temperature rating of -55° C to 105° C. EMS features a flexible core constructed of a helically wound, fully interlocked strip of bronze. An all-temperature PVC jacket is extruded over the core, resulting in a sealed, waterproof raceway when assembled with liquidtight fittings.

· BEST Shielding: Type EMCS® is a hybrid of SLA and EMS because it utilizes the same bronze core and PVC jacket as EMS but gets further screening protection from a tinned copper braid as found in the SLA product. Type EMCS offers the same working temperatures as EMS.
