Neglecting to pay due attention to some of these factors may causeunnecessary anxiety at a future point in time when the equipment and cables have been delivered on site, but for example the cable glands have either been forgottento be ordered or it is discovered that they are the incorrect type or size at the very point when they are needed the most. Good advice would be to allocate some valueadded planning and preparation time to the subject of cable gland selection so as to avoid the great inconvenience which is likely to occur at a critical point in time. Inthe event that a user or contractor is in possession of a cable schedule that requires a cable gland selection and sizing process to be carried out, CMP Products would bemore than happy to assist in carrying out this process at no cost to the enquirer. Please contact CMP Products for further information on this subject.Here is a summary of some aspects to carefullyconsider when selecting cable glands.• Identify the type of cable to be used.• Check the construction, size & material properties ofthe cable.When the cable is armoured, verify the following :-• Check the type and material of the cable armour (*)• Check the short circuit fault current rating of the cablearmour (**)• Check the actual diameter of the inner bedding(where present) against this catalogue.• Check the actual diameter of the lead covering (wherepresent) against this catalogue.• Check the actual size of the overall cable diameteragainst this catalogue.• Check the size and type of armour or braid (wherepresent) against this catalogue.• Check any special environmental requirements inrelation to corrosion protection.• Check the material of the mating electrical enclosuresto eliminate dis-similar metals.• Consider whether any protective plating is required tobe applied to the cable gland.• Check the type and size of the cable entry hole in themating electrical equipment.• Check the ingress protection rating of the electricalequipment or site standard• Check whether a single seal or double seal cablegland is required.HOW TO ORDEROn each of the main product pages in this catalogue you will find a cable glandselection table which includes the part number, typically of a standard metricproduct, for ordering purposes.e.g. 1: 20 - E1W - Brass, with M20 entry thread• Check whether an entry thread seal is required forIP66 (or IP67/IP68) conditions.• Check whether fixing accessories such as locknuts andserrated washers are required.• Check whether earth tags are required.(**)• Check whether shrouds tags are required.• Select a corresponding cable gland type from thiscatalogue.• For installations in Hazardous Areas, specialconsiderations should be taken into account to ensurecompliance with national or international codes ofpractice.• Check whether a thread conversion adaptor / reduceris required to make the installation.• Select corresponding adaptors or reducers from thiscatalogue.• Check whether any stopper plugs are required toclose unused cable entries.• Select corresponding stopper plugs from thiscatalogue.Note (*) : If the cable armour is of a non standard material,e.g. Aluminium Wire Armour, it may be necessary to consideran alternative cable gland material, e.g. Aluminium.Note (**) : For certain medium voltage and high voltagecables where the fault current carrying capacity of the cablearmour is greater than that of the standard earth tag it maybe necessary to consider a cable gland utilising the CMPheavy duty Cast Integral Earth Lug (CIEL) option which canbe identified in the body of this catalogue.The table below is provided to allow the selection of alternative materials, threadtypes, thread sizes and other options.The part number is composed of the CMP Size, Type Number, and Standard Suffix.e.g. 2 : 20 – E1FW – Nickel Plated Brass, with M20 entry threadSize Type Standard Suffix ID Size Type Standard Nickel PlatedSuffix ID FinishCableGlandSizeAvailable Entry Threads ‘C’StandardOptionMinimumThreadLengthCableBeddingDiameterMetric NPT NPT Min MinAcrossFlatsAcrossCornersNominalProtrusionLengthOrderingReference(Brass Metric)20S/16 M20 1/2” 3/4” 10.0 3.1 8.7 24.0 26.6 21.0 20S16XX1RA20S M20 1/2” 3/4” 10.0 6.1 11.7 24.0 26.6 21.0 20XX1RA20 M20 1/2” 3/4” 10.0 6.5 14.0 27.0 30.0 24.0 20XX1RA25 M25 3/4” 1” 10.0 11.1 20.0 36.0 39.9 26.0 25XX1RA32 M32 1” 1 1/4” 10.0 17.0 26.3 41.0 45.5 27.0 32XX1RA40 M40 1 1/4” 1 1/2” 15.0 23.5 32.2 50.0 55.4 28.0 40XX1RA50S M50 1 1/2” 2” 15.0 31.0 38.2 55.0 61.0 29.0 50SXX1RA50 M50 2” 2 1/2” 15.0 35.6 44.1 60.0 66.5 30.0 50XX1RA63S M63 2” 2 1/2” 15.0 41.5 50.0 70.0 77.6 30.0 63SXX1RA63 M63 2 1/2” 3” 15.0 47.2 56.0 75.0 83.2 30.0 63XX1RA75S M75 2 1/2” 3” 15.0 54.0 62.0 80.0 88.7 32.0 75SXX1RA75 M75 3” 3 1/2” 15.0 61.1 68.0 85.0 94.2 32.0 75XX1RA90 M90 3” 3 1/2” 15.0 66.6 79.4 108.0 120.7 44.0 90XX1RA100 M100 4” -
