Instrumentation cable-CY Cables are widely used and popular in the cable market.And for the Instrumentation Cable-CY Cables, CY means Copper wire braid screen between the inner and outer sheath,the covering should not lower than 85% as common.
The cable conductor is flexible Copper wires Class 5 according to IEC 60228.We can often known that the instrumentation cables are of multi-cores,the different cores are identified with black cores with continuous white numbers on.There can also be green-yellow earth core in the outer layer. Please see below pictures of Instrumentation Cable-CY Cables:
It is usually flexible cable with Copper Wires and PVC insulation and sheath,screen made of tinned Copper wire braid.The instrumentation cables are suitable for installation in power networks,in control and signaling networks,in machines and equipment,assembly lines and installations.It is often widely used for offshore works,for Oil and drilling platforms,gas engineering.
