What are control cable? What is its applications?
Control cables are cables that transmit control signals from the control panel to equipment and machinery. The rated voltage of control cables is usually 450/750 V, whereas power cables are typically 0.6/1 kV. This difference means that, for the same specifications, the sheath of control cables will be thinner than that of power cables. Control cables typically have a small cross-sectional area, a higher number of cores, and carry small currents, mainly for transmitting control signals and start-stop functions.
Key Applications of Control Cables
Control cables have a wide range of applications, including:
- Data signal cable
- Computer cable
- Can Bus cable
- Servo motor cable
- Robotic cable
- Drag chain cable
Common Types of Control Cables
Control cables come in various standard types, including:
- VDE0250 Standard:
- LiYY
- LiYCY
- LiYCY-TP
- YY
- CY
- YSLY
- YSLY-OZ
- UL2464 Standard:
- Multi-conductor cable series
- Multi-pair cable series
- Multi-conductor shield cable series
- Multi-pair shield cable series
- Chinese Standard:
- RVV
- RVVP
- KVV
- KVVP
- TRVV
- TRVVP
In addition to these standardized models, leading cable companies like LAPP, Helukabel, Belden, and Igus also have their own standardized control cable models, such as Helukabel’s JZ series.
Factors need to consider when Choosing Control Cables
When choosing a control cable, consider the following points:
- Temperature Range: The common usage range is -15℃ to 75℃.
- Nominal Voltage: European voltage is generally 300/500V or 450/750V, and UL is 600V.
- Core Insulation Material: Options include PVC, TPE, rubber, PUR, and other special materials.
- Shield: Options include foil aluminum and tinned copper.
- Outer Sheath Material: Options include PVC, PUR, rubber, and other special materials.
- Application Scenarios: Suitable for drag chain systems, open air, robots, and general machinery.
- Cable Characteristics: Consider halogen-free, chemical resistance, oil resistance, weather resistance, and abrasion resistance.
