† Grooved Cone (X) is predominantly used for Wire Braid (e.g. GSWB, TCWB), Steel Tape Armour (STA, DSTA) and Aluminium Strip Armour (ASA) but is also suitable for Single Wire Armour (SWA), Aluminium Wire Armour (AWA) and Pliable Wire Armour (PWA) if the range is outside that of the Stepped Cone (W).

Note: Grooved Cone (X) dimensions shown in the Cable Gland Selection Table below are for a double wire strand of braid armour cables. Tapes can also be doubled over. For cables that have only a single layer of armour such as SWA the clamping range should be used as shown in the table below.

Stepped (W) Cone is suitable for Single Wire Armour (SWA), or Aluminium Wire Armour (AWA) cables.

CMP Ingress Protection Testing

Some CMP cable gland types have been tested to IP66, whilst other types have been tested to IP66, IP67 & IP68, to an equivalent depth of up to 60 metres for a duration of two weeks. For manufacturers to claim an IP68 protection level it is important that they include both the depth of water and time duration of the test conducted; otherwise the rating would be incomplete and meaningless.

Material Selection & Preservation for Longevity of Service

The selection of material by a customer often comes down to either carefully developed client specifications; cost / value options; or a combination of both. There will be numerous applications where the material selection is a lot more critical than it is in others.
