Additional Information

Cable Gland for Cables Entering Ex e & Ex i Equipment

Although the minimum requirements for Ex e and Ex i enclosures could be met by cable glands with a single outer seal, the majority of users prefer to standardise on a double seal cable gland, to maintain a site standard, and ensure that cable gland types are not inadvertently mixed between different types of equipment protection.

Alternative Cable Gland Termination Concepts

Although there may be a perception that some cable glands employing a sealing ring on the cable inner bedding are more suitable for “soft bedded” cables, since there is no strict definition of what soft bedded really means, it is impossible to make that judgement for any cable gland when the cable is not made to accept even the least amount of pressure applied by a sealing ring.

Certification – CSA, cCSAus, UL & cULus

Confusion exits in the market regarding the use and meaning of certification marks such as cCSAus and cULus. Manufacturers can choose to use one or more Nationally Recognised Testing Laboratory (NRTL) to list their products for use in hazardous (Classified) locations.
