Tianjin Beida Cable Group's 450/750V Screen Control Cable adopts copper tape or copper wire braided shielding layer to effectively prevent electromagnetic interference and ensure clear signal transmission. This makes it an ideal choice for high electromagnetic interference environments such as power plants and power stations. For equipment requiring highly stable signals, cables can effectively reduce noise interference and improve system reliability. Even in complex power systems, accurate signal transmission can be maintained to ensure safe and efficient operation of equipment.
450V screen control cable:
Rated voltage: 450V (phase voltage), that is, the power frequency voltage that the cable design can withstand for a long time is 450 V.
Application scenarios: suitable for control circuits in low voltage distribution systems, such as equipment control, signal transmission, monitoring circuits, etc., common in indoor fixed laying environments (such as cable trenches, pipelines).
Typical models: such as KVVP (copper core PVC insulated PVC sheathed braided shield control cable), its shielding coverage ≥85%, can effectively suppress electromagnetic interference.
750V screen control cable:
Rated voltage: 750V (line voltage), that is, the power frequency voltage that the cable design can withstand for a long time is 750 V.
Application scenarios: suitable for control circuits requiring higher voltage levels, such as industrial automation equipment, control lines in power transmission systems, or scenarios requiring higher voltage stability.
Typical model: some specially designed screen control cables may be marked with 750V voltage level, but it should be noted that 750V is more line voltage standard, and the actual product may be marked in the form of 450/750V combination (such as 450V phase voltage/750V line voltage).
