FAQ

FAQ
Q1: What is the difference between thermocouple grade and extension grade Type K cable?
A: Extension grade (KX) uses the same alloy materials as thermocouple grade (Chromel and Alumel) but is designed for connecting from the probe to instrumentation in cooler areas. Both provide accurate signal transmission within their respective temperature ranges.
Q2: Why is XLPO insulation used instead of PVC for this cable?
A: XLPO (cross-linked polyolefin) offers superior thermal stability, improved mechanical strength, and enhanced electrical properties compared to standard PVC insulation, while maintaining fire safety characteristics.
Q3: What does the overall screen with drain wire provide for thermocouple signals?
A: The aluminium/polyester tape screen with tinned copper drain wire protects the weak thermoelectric signal from electromagnetic interference and crosstalk from nearby power cables and machinery, ensuring accurate temperature readings.
Q4: What is the voltage rating and standard for this cable?
A: This cable is rated at 300/500V and manufactured to EN 50288-7 and IEC 60584-3 standards for instrumentation and thermocouple extension applications.
Q5: Is this cable suitable for outdoor installations?
A: Yes, the LSZH outer jacket provides UV resistance, moisture protection, and weathering resistance, making it suitable for external building walls and open-air cable tray routing.
