ZR-DJYPVP shielded screen instrument cable

ZR-DJYPVP individual shielded overall shielded screen instrument cable is suitable for use in automatic control systems, computer distributed control systems, automated control systems as control lines in electric power, metallurgy, petrochemical and other industries where the AC U0/U is 300/500V, as well as electronic computers for testing instruments and meters. DJYPVP cables usually adopt separate shielding structure or total shielding structure. These two structures are different in the anti-interference ability and signal transmission quality of the cable.

Separate shielding structure
The sub-shielding structure of DJYPVP cable includes conductor, insulation layer, conductor shield, total shield, sheath and other parts. Conductor shielding in a separate shielding structure means that each group of insulated twisted pair core wires and three pairs of core wires are wrapped in a shielding layer, while total shielding means that all insulated core wires are wrapped in a common shielding layer. The separate shielding structure can reduce the interference between each core wire and improve the stability of signal transmission. It is suitable for occasions with high signal interference requirements.
Total shielding structure
The total shielding structure of DJYPVP cable means that all insulated core wires are wrapped in a common shielding layer. This structure can provide more comprehensive shielding protection, reduce the impact of external electromagnetic interference on signal transmission, and is suitable for signal stability. Extremely demanding environments, such as medical equipment, precision instruments, etc,ZR-KVVP ZR-KVVRP control cable.
