Extension cable and wire in the thermocouples

General-purpose PVC insulated and sheathed, extension wires or cables have good moisture proof wear and flame proof properties. For continuous extruding technology being employed, heat-resistant, fluoroplatics insulated and sheated extenion wires or cables have improved advantages, eg. enduring high temperature extreme cold, acid/alkaline oil or water and aging the products can meet the requirements of GB/T 4989-94 (equal to IEC548-3). The extension wires used in the intrinsically safe, explosion-proof temperature-measuring system employ low-capacity, low-inductance material, which is explosion-proof. They are used under the dangerous condition to form an intrinsically safe thermocouple temperature measureing system.
