E1FU | Ex eb, Ex db, Ex nR, Ex ta | Explosive Atmosphere Cable Gland For all types of Armoured cables

Globally Approved, Explosive Atmosphere Cable Gland

• Metal-to-metal armour clamping
• Direct & remote installation
• Displacement type flameproof inner seal
• Controlled outer ‘load retention’ seal
• Unique OSTG prevents overtightening
• Designed to prevent Coldflow, see CMP Technical Document TS001 (available upon request)
• -60°C to +130°C
• Globally marked, IECEx, ATEX & cCSAus
• Superior EMC performance

Note: † Grooved Cone (X) is predominantly used for Wire Braid (e.g. GSWB, TCWB), Steel Tape Armour (STA, DSTA) and Aluminium Strip Armour (ASA) but is also suitable for Single Wire Armour (SWA), Aluminium Wire Armour (AWA) and Pliable Wire Armour (PWA) if the range is outside that of the Stepped Cone (W). Note: Grooved Cone (X) dimensions shown in the Cable Gland Selection Table below are for a double wire strand of braid armour cables. Tapes can also be doubled over. For cables that have only a single layer of armour such as SWA the clamping range should be used as shown in the table below. Stepped (W) Cone is suitable for Single Wire Armour (SWA), or Aluminium Wire Armour (AWA) cables. For under / oversized armour wires click here

Additional Information

Restricted Breathing (Ex nR) Equipment

Usually Ex n equipment contains components that are either non–sparking or energy limited such that ignition can be prevented when gas or vapours enter the enclosure. Restricted breathing enclosures type ‘nR’ ensure that the flammable mixture is kept away from any hot surfaces and any ignition capable components. The features of a typical Ex nR enclosure would often include:

Typical Installation Configurations

The illustrations provided below are indicative of some of the common methods of installation configurations adopted. These are for informative guidance only and relevant site conditions along with any specified National or International codes of practice must always take precedence. The accessories available offer a wide, flexible approach in mounting, sealing and earthing connection provision. Selection and installation according to the Engineering Specification may vary from these illustrations.
