Control cable refers to the cable of ordinary transmission signal and control line. Without special requirements, it has no shielding function. Shielded cable refers to the cable that can shield magnetic interference and other cables for protection and transmission. It is generally represented by the letter "P". Difference between the two: shielded cable can replace control cable, but control cable cannot replace shielded cable. Shielded cable is suitable for places requiring shielding.

Model and letter meaning of shielded control cable: RVVP copper core PVC insulated PVC sheathed braided shielded flexible wire and cable; Rvvp2 copper core PVC insulated PVC sheathed copper tape shielded flexible wire and cable; Rvvp3 copper core PVC insulated PVC sheathed aluminum-plastic composite tape shielded flexible wire and cable; Rvvp2-22 copper core PVC insulated PVC sheathed steel tape armored shielded wire and cable. Relevant parameters of shielded cable: the AC rated voltage of shielded cable is 3.6/6kv, the long-term working temperature of cable conductor is 90 ℃, the z.ui small bending radius of cable is 6 times of cable diameter, the cable shall not be exposed to sunlight for a long time, and the bottom core of cable must be well grounded. Common model and letter meaning of control cable: KVV copper core PVC insulated PVC sheathed control cable;

Kvvp copper core PVC insulated PVC sheathed braided shielded control cable; Kvvrp copper core PVC insulated PVC sheathed braided shielding control flexible cable; Kvvp2 copper core PVC insulated PVC sheathed copper tape shielded control cable; Kvvp3 copper core PVC insulated PVC sheathed aluminum-plastic composite tape shielded control cable; Kvvp-22 copper core PVC insulated PVC sheathed braided shielded steel tape armored control cable. Relevant parameters of control cable: the AC rated voltage of control cable is 450 / 750V, the long-term working temperature of conductor core is 70 ℃ and 95 ℃, and the cable laying temperature is not lower than 0 ℃; The bending radius of shielded flexible cable shall not be less than 6 times of the outer diameter of the cable, and the control flexible cable can be used in occasions with movement requirements.
