300V UL Type PLTC/ITC instrument cables utilize high-quality multi-strand bare copper conductors, offering excellent electrical conductivity and flexibility to meet the requirements of complex wiring environments. Each pair or three-pair cable is independently shielded, employing aluminum/polyester foil layers with tinned copper leads to effectively suppress electromagnetic interference and signal crosstalk, ensuring stable transmission of instrument signals. The conductor insulation uses flame-retardant PVC (XLPE optional), balancing heat resistance and mechanical strength. The cable's internal structure is maintained by polyester insulation tape and polypropylene filler, while the overall outer sheath is flame-retardant PVC, providing excellent abrasion resistance, oil resistance, and UV resistance, suitable for indoor cable trays, cable ducts, direct burial, and outdoor installations.
Application
UL Type PLTC/ITC Instrument Cables
PLTC/ITC instrumentation cables are primarily used in industrial instrumentation and control systems where signal stability, interference immunity, and mechanical protection are critical. These cables are typically used in PLC, DCS, and process control systems to connect various sensors, transmitters, actuators, and control devices, suitable for transmitting 4–20 mA analog signals, low-level control signals, and industrial communication signals.
In industrial environments such as petrochemical, power, energy, metallurgy, water treatment, and manufacturing plants, cables often need to be laid in parallel with motors, frequency converters, and high-power equipment. Multiple pairs or sets of three-core independently shielded structures effectively reduce crosstalk and electromagnetic interference, ensuring long-term signal stability and reliability.
Certification
300V UL Type PLTC/ITC instrument cable is UL certified and meets stringent flame retardant and heat resistance standards. Whether laid in cable trays, trunking, or direct burial, it ensures cable safety under industrial operating conditions, providing reliable protection for factories and control systems. UL-certified cables undergo weathering, UV resistance, and low-temperature bending tests, making them suitable for indoor, outdoor, direct burial, and cable tray environments. The cable operates stably in both factory workshops and outdoor machinery.
