There are lots of questions and answers about sy and cy cables but nothing seems to state if the braiding should be earthed by that i mean not used as an earth.
What is the difference between cy and sy cable.
The main cable types used are cy cables sy cables and yy cables which are also referred to as flexible instrumentation cables.
However they have different constructions.
Complementing the veriflex range that includes the commonly specified sy cy and yy cables is our extended automation cable portfolio providing a broad selection of industry specific cables to support any installation or application requirement.
The main kinds of control cables are three in total which are inclusive of cy sy and yy cables.
The control cable basically has a voltage of 300.
They are designed for use as interconnecting cable in control and signal equipment for measuring control and regulation.
These cables are available either from stock or on minimal lead times 4 6 days to match even.
All the cables play a significant part in conductivity in the automation field.
Or ls0h material is required in material properties which is another category of low smoke halogen free and halogen free cables.
Sy control cable can be referred to more generally as instrumentation cable flexible or braided control cable and control flex.
The main differences between the three cables are.
Where the sy cable is sufficient on its own the yy and cy control cables work together in order to achieve many goals.
The subtle difference is that some people say that it is a shielded cable cy some say a shielded flexible cable sy or an unshielded control cable yy.
Cannot be touched then no earthing is required.
It appears to be that if the cable passes through an insulated gland and the braiding at the ends is insulated i e.
There are three different types of control cable in the area of process automation.

There is no provision in bs en 50525 2 11 for any braid and hence a braided cable such as sy cable cannot conform to this standard.
