Identify the armour layer and its construction
- Armoured cable
A separate armour layer surrounds the cable’s inner covering. Identify its form and dimensions before selecting the clamp.
- Non-armoured cable
This example has no armour layer. Sealing and retention use the cable construction actually present.
- AWA
Aluminium wires provide the specified armour construction. Material cannot be identified reliably from the outline alone.
- STAThis term
Overlapping tapes differ from wire armour. A wire cone-and-clamp design must not be assumed suitable for tape armour.
A cable can have no armour, wire armour or tape armour. The gland must suit the actual cable layers, armour dimensions and required bonding arrangement.
Conceptual cable sections. Steel and aluminium wire armour are shown with the same geometry because material identity requires the cable specification.
