Overview
The Younxin Ex db Armoured Double Seal Cable Gland is configured for armoured cables entering hazardous-area electrical equipment. It combines armour termination with compression sealing at the cable inner bedding and outer sheath, helping create a stable cable-entry interface when the gland is correctly selected, assembled and installed.
Selection is based on the complete cable construction, including both sheath diameters and the armour dimensions. The final explosion-protection marking, certificate scope, ingress protection, service temperature, material and size are confirmed for the ordered configuration before approval or installation.
Key Features
- Two project-matched sealing locations: one at the cable inner bedding and one at the outer sheath.
- Integrated armour termination for mechanical retention and electrical continuity where required by the installation design.
- Selected using actual inner-bedding, outer-sheath and armour dimensions.
- Configurations can be reviewed for steel wire, steel tape, wire braid and aluminium armour constructions.
- Metal body and entry-thread options support different enclosure and corrosion requirements.
- Optional shroud, earth tag, locknut and entry sealing accessories can be supplied as a coordinated set.
Materials and Entry Threads
The fields below are typical project-selection options. Availability and the applicable approval scope must be confirmed for the exact size and configuration.
| Body material | Nickel-plated brass or stainless steel; specify the required stainless grade and corrosion environment. |
|---|
| Entry thread | Metric, NPT or G thread options can be reviewed to suit the enclosure entry. |
|---|
| Inner seal | Compression seal selected to the cable inner-bedding diameter and cable construction. |
|---|
| Outer seal | Compression seal selected to the cable outer-sheath diameter and service conditions. |
|---|
| Armour interface | Selected to the armour type, armour diameter and wire or tape thickness. |

Applications
- Oil and gas facilities, refineries and petrochemical plants
- LNG, chemical processing and bulk storage projects
- Offshore modules, marine equipment and shipbuilding
- Power generation, mining and heavy industrial installations
- Hazardous-area junction boxes, motors, control stations and instrument enclosures
Application suitability depends on the project hazardous-area classification, cable construction, enclosure certification, environmental exposure and installation standard.
Selection Data Required
For an accurate quotation and technical review, please send:
- Cable manufacturer, cable type or datasheet
- Diameter over inner bedding or under armour
- Overall cable diameter over the outer sheath
- Armour type, armour diameter and wire or tape thickness
- Enclosure entry thread, thread size and required engagement length
- Preferred body material and site corrosion conditions
- Ambient and operating temperatures
- Required hazardous-area marking, approval scheme and project specification
- Required accessories, quantity and document package
Accessories
A coordinated accessory set may include a protective shroud, earth tag, locknut, sealing washer or O-ring, and approved adaptor or reducer where the enclosure entry requires one. Accessory material and size are matched to the selected gland and installation.
Frequently Asked Questions
How does a double-seal armoured gland work?
The gland uses separate compression seals at the inner bedding and outer sheath while its armour components terminate and retain the cable armour. Correct performance depends on matching all three interfaces to the cable dimensions.
When should I select a compound barrier gland instead?
A barrier gland may be required when the project specification calls for a cured seal around individual cable cores. The choice cannot be made from cable diameter alone; confirm the cable construction, equipment protection concept and applicable installation rules.
Can one size be used for different armour types?
Only when the selected gland configuration covers the actual sheath and armour dimensions. SWA, steel tape, braid and aluminium armour use different interfaces, so the cable datasheet should be checked before ordering.
Is IECEx or ATEX documentation included?
The required approval scheme must be stated at the enquiry stage. Certification is specific to the model, size, material and configuration. Younxin will confirm the applicable marking and provide only the documents that cover the supplied item.
