Cable Gland Material Selection
There are numerous different grades of materials used for the production of cable glands by different manufacturers and it is important to identify the precise grades used before proper and effective evaluation can be achieved. Given the range of potential environments, including indoor and outdoor, the compatibility and the selection of material used in the production of cable glands is very important.

The IEC 60079-1 standard allows the use of threaded adaptors and reducers for direct entry into Flameproof type ‘d’ enclosures. In future, the female connection threads of the adaptors and/or reducers will be limited to metric or NPT only. When using thread adaptors and reducers or reducer bushings, only one is permitted for any single cable entry of Flameproof type ‘d’ (Ex d) equipment.

Accessories may be required to ensure the correct installation of cable entries for a combination of security, sealing and earthing reasons. Security refers to ensuring that the device is fastened tightly to the enclosure in a way that would prevent the loosening of components over time. This is a critical aspect of the installation which needs to be assured in the most arduous conditions, including during periods of severe vibration that may occur during normal operation.
