What is the difference between cy and sy cable.

Cy and yy control cables. The main cable types used are cy cables sy cables and yy cables which are also referred to as flexible instrumentation cables. 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. These cables are available either from stock or on minimal lead times 4 6 days to match even.

The uk standard for pvc insulated and sheathed flexible cables is bs en 50525 2 11 and some manufacturers of sy cy and yy cables claim conformity with this standard. They are designed for use as interconnecting cable in control and signal equipment for measuring control and regulation. There are three different types of control cable in the area of process automation. It appears to be that if the cable passes through an insulated gland and the braiding at the ends is insulated i e.

The main kinds of control cables are three in total which are inclusive of cy sy and yy cables. Cannot be touched then no earthing is required. The control cable basically has a voltage of 300. All the cables play a significant part in conductivity in the automation field.

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. 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. 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.

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. Where the sy cable is sufficient on its own the yy and cy control cables work together in order to achieve many goals. With its gswb braid sy is suited to installations with medium to high mechanical stress. However they have different constructions.
