Thermocouple extension wire:
Implanted standard:
GB/4989-94 standard is equivalent to IEC584-3 standard.
Flame-proof property accord with GB/T18380.3(idt.IEC60332-3)
Characteristics and Application:
Thermocouple wire and cables are used to extend the cold ends of the thermocouples in the temperature testing systems. The cable is used import PVC insulation and sheath. It has good property to resistance water, attrition and flame.
Application characteristics:
1. The operation temperature: 700C or 1050C
2. The lowest environment temperature: -400C, Non-Fixed deploying: -15oC
3. Fixed deploying: laying temperature of the cable:
4. Permitted bending radius: Permitted bending radius is not smaller than 12 times outer diameter of the cable with copper tape wrapping shield and 6 times for other cables.

Q&A:
1. Q:How to choose the sheath type of cable?
A.:There are four commonly used sheath types, PUR, PVC, TPE, TPEE.
The PUR sheath has good elasticity, softness, good mechanical properties, good resilience, and is not easy to deform. The price of PVC sheath is cheap, if you do not have high requirements for the resilience of the wire, you can choose PVC sheath. The TPE sheath is super soft, and the temperature range is -40ºC~+80ºC, but its disadvantage is that it is not resistant to oil and its mechanical properties are not as good as PUR. Its price is lower than PUR and higher than PVC. TPEE has good temperature resistance. The temperature range is -40ºC to +100ºC. It has good resilience and mechanical properties, but it is not soft enough and the price is higher than PUR.
2. Q.:Are you a factory or trading company?
A: We are a factory, and we establised in 2007.
3. Q: What kind of electric wire and cable do you produce?
A: We produces various kinds of Electric wire and Power cable: PVC Cable, XLPE Cable, Control Cable, Flexible Cable, Spiral Cable, Signal Cable, Data Cable(Cat6, Cat5e,Patch cord),Teflon wire and High temperature Wire Cable, Rubber Cable, Elevator cable, Crane cable, Solar cable and different industrial Cables, Conductor (AAC, ACSR, AAAC, Bare copper conductor and Stay wire)
4. Q: Is sample supplied if requested?
A: Yes!
5. Q: What certificates do you have?
A: We have been qualified with IEC, CCC, CE, RoHS.
