UL Type PLTC / ITC armored thermocouple extension cable uses high-quality thermocouple alloy conductors, with each pair of conductors independently shielded with aluminum/polyester, promoting stable signal transmission. The cable is fully encased in interlocking aluminum armor, enhancing mechanical protection against external damage and crushing. The outer sheath is made of flame-retardant PVC, which is abrasion-resistant and chemically resistant, adapting to the complex environments of industrial sites. Conductor specifications are available in AWG16 or AWG18, supporting various conductor pair configurations for different installations.
Application
PLTC / ITC Armored Thermocouple Extension Cable
Armored thermocouple extension cables are widely used in industrial automation, energy, petrochemical, mining, and water treatment applications to safely and reliably transmit field thermocouple signals to control systems. Their abrasion resistance, chemical corrosion resistance, and armored protection make them particularly suitable for use in high-temperature, humid, or mechanically impacted environments. The cable can be laid in cable trays, pallets, or protected conduits to extend thermocouple signals and achieve accurate measurement.
Certification
Thermocouple extension cable has obtained multiple UL certifications, including UL13 (PLTC), UL2250 (ITC), and UL83 (thermoplastic insulated conductor standard), which allows for safe use in cable trays, conduits, and complex industrial environments, contributing to intact and stable signals during long-distance transmission.

FAQ
Q: Can thermocouple extension cables replace ordinary signal cables at will?
A: No, thermocouple extension cables use special alloy conductors to match the thermocouple type (K, J, T, etc.). Ordinary copper wire cannot guarantee temperature measurement accuracy, and using the wrong wire can lead to signal deviation or even failure.
Q: Are all PLTC/ITC cables suitable for thermocouple signals?
A: No, ordinary PLTC/ITC cables are designed for low-voltage control or instrumentation signals, while thermocouple extension cables use special conductor alloys, shielding, and color-coded matching to ensure temperature measurement accuracy and signal integrity.
Q: Is shielding only for preventing electromagnetic interference (EMI)?
A: Not entirely. In addition to EMI protection, shielding also provides overall structural integrity in armored and cable tray wiring, preventing noise and signal interference caused by wire contact.
