Control cables refer to ordinary cables for transmitting signals and control lines, with no special requirements and no shielding function. Shielded cables refer to cables that can shield magnetic interference and other protection and transmission functions, and are generally represented by the letter P. The difference between the two: shielded cables can replace control cables, but control cables cannot replace shielded cables, and shielded cables are suitable for places where shielding is required. Shielded control cable model and letter meaning: RVVP copper core PVC insulated PVC sheath braided shielding flexible wire and cable; RVVP2 copper core PVC insulated PVC sheathed copper tape shielded flexible wire and cable; RVVP3 copper core PVC Ethylene 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. Related parameters of shielded cable: AC rated voltage of shielded cable is 3.6/6KV, long-term working temperature of cable conductor is 90°C, minimum bending radius of cable is 6 times of cable diameter, cable should not be exposed to sunlight for a long time, cable bottom core must be well grounded . Common types and letter meanings of control cables: KVV copper core PVC insulated PVC sheathed control cable; KVVP copper core PVC insulated PVC sheathed braided shielded control cable; KVVP copper core PVC sheathed braided Shielded control flexible cable; KVVP2 copper core PVC sheathed copper tape shielded control cable; KVVP3 copper core PVC sheathed aluminum-plastic compound tape shielded control cable; KVP-22 copper core PVC sheathed braided shielded steel tape sheath Set of control cables. Control cable related parameters: the AC rated voltage of the control cable is 450/750V, the long-term working temperature of the conductor core is 70°C and 95°C, and the laying temperature of the cable is not lower than 0°C; the bending radius of the shielded flexible cable is not lower than the outer diameter of the cable 6 times, the control flexible cable can be used in occasions with mobile requirements. .
