SY JB/OB armoured control cable has colour coded cores and a bedded galvanised steel wire braid (GSWB) which provides excellent protection against mechanical damage.
These flexible and versatile SY JB/OB cables are used for connecting, measuring, checking and control applications.
Suitable for installation in dry and moist rooms, outdoor installation not recommended.
If protection against mechanical (physical) damage is not required please see our range of YY control cables. If protection against electrical interference is required please see our range of CY screened control cables.
