Signal cables are used for signal delivery on every kind of automatic device links. Thisdigital cable is a vital component for the signal systems of railroads, power stations, factories, mineral mines, and ports.

Reference standard: As per company standard

Working conditions of signal cable
1) Max working temperature of the cable conductor is 70℃
2) The common structure insulated cable is suitable for equipment under mains frequency or DC equipment. The cable with a complex stranded core is suitable for equipment within audio frequency range and electrical equipment needing a shielded cable.
3) Temperature during installation should be no lower than 0℃.
4) The minimum bent radius of the cable is 12D.

The specification scope of the signal cable
1) Conductor diameter: 0.8mm 1.0mm
2) Cable core number: 2~48core

Type	Description
PVV	Signaling cable with PVC insulation & sheath
PYV	Signaling cable with PE insulation PVC sheath
PVV22	Signaling cable with PVC insulation & sheath, steel tape armor
PYV22	Signaling cable with PE insulation PVC sheath, steel tape armor

Note ： PYV,PYV22 The signal delivers the function better than PVV, PVV22 ， Recommend to choose to use PYV and PYV22
