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.
Read moreCable 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.
Read moreCable Deformation with Temperature Change
Another factor to consider is that when cables are installed in connection with offshore electrical equipment, the temperature passing through the cable when the circuits have been energised can quite easily reach +70°C and above over prolonged periods.
