PXSS2KREX | Ex eb, Ex db, Ex nR, Ex ta | Explosive Atmosphere Barrier Cable Gland For all types of Unarmoured & Braid Cables

Globally Approved, Explosive Atmosphere RapidEx Barrier Cable Gland

• RapidEx liquid pour sealing system
– Enhances reliability, reduces risk
– Reduces man hours
– Reduces cost
• Direct & remote installation
• Superior levels of cable retention
• Displacement type environmental seal
• Designed to prevent Coldflow
• Deluge protected
• -60°C to +85°C

Additional Information

IEC 60079-1 – Flameproof Path Properties

A flameproof joint or flame path is defined by IEC 60079-1 as a “place where the corresponding surfaces of two parts of an enclosure, or the conjunction of enclosures, come together and which prevents the transmission of an internal explosion to the explosive gas atmosphere surrounding the enclosure”.

Overview of Different Flameproof Sealing Methods

Considering the requirements for Flameproof type ‘d’ (Ex d) enclosures and the need for cable glands to maintain the integrity of the protection method by containment, we can observe the different options available to achieve this. Recognition must first be given to the fact that cables must be robust enough to enable a sealing ring to be applied, and ensure safety of installations. See also Clause 9.3.1 of IEC 60079-14:2013.

Compatibility of Equipment, Cable & Cable Gland

It is essential that the cable gland is compatible with the cable with which it is intended to be installed with, and the combination of both cable and cable gland is capable of maintaining the integrity of the connected equipment. The long term technical integrity of any plant or project relies heavily on the correct selection of cable and cable glands to suit the installation. Emphasis on the selection process requires careful thought and significant attention to a lot of variable factors that ought to be taken into account.

IECEx Certification

The IEC (International Electrotechnical Comission) develops international standards and operates conformity assessment schemes in the fields of electrotechnology. One such scheme, IECEx is a single global certification scheme, based on IEC and ISO international standards.

Types of Sealing Rings

Some cables, that bear low smoke and fume, zero halogen or halogen free characteristics may have an inner bedding that is extruded from a compound which has not been fully cured during the manufacturing process. This is often referred to as a soft bedding, and brings an additional factor to consider when selecting appropriate cable glands.

Meeting the ATEX Directive

Applicable to the ATEX Directive 2014/34/EU are a number of conformity assessment procedures or modules and the circumstances when they must be used are determined by the nature of the equipment, product or protective system, and whether they are bespoke one-off solutions, or repeat items manufactured in batch production set up.

ATEX & CE Marking

CE Marking i.e. Conformité Européenne, meaning European Conformity was introduced to enable the free movement of goods, products and equipment within the European Economic Area (EEA). When applying the CE mark to any item, the manufacturer is declaring that it complies with the requirements of all applicable European Directives. The CE mark should only be applied when the type of product falls within the scope of the Directive that is detailed in a corresponding EC Declaration of Conformity.
