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”.

Cable Gland for Cables Entering Ex d & Ex n Equipment

The following page identifies and illustrates the minimum requirements for flameproof type ‘d’ (Ex d) and type of enclosure protection ‘n’ (Ex n) cable glands.

Cable 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.
