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.
