1. Introduction:
Thermocouple Extension cable is usually used to connect thermocouple and display-controled meters in order to lower the inaccuracy caused by temperature change on the connections.

2. Construction:  
Conductor: original thermocoupole alloy material, in solid wire or strand wires
Insulation Layer:
Fiberglass              (ambient temperature range 0-300ºC
 PVC                       (ambient temperature range 0-105ºC)
 Telflon                  (ambient temperature range 0-350ºC)
 Silicone rubber   (ambient temperature range 0-180ºC)
Jacket layer materials: fiberglass, PVC, teflon, silicone rubber
Galvanized layer: stainless steel, tinned brass

3.Standard: conforms to IEC584 standard.

2  Conductot dimension:
2*7/0.3 means 2 cores,  each core includes 7 strands wire,
each wire diameter is 0.3mm, more example: 2×7/0.2, 2×4/0.65, 2×1/0.3 etc.
Other way to symbol the conductor dimensions:
Conductor square meter: 0.25mm²
AWG standard (see*Table 2)
