Electric Wires Cables AWG Flexible 2 3 Core Copper Electric Wire

 

 

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)
 PFA                  (ambient temperature range 0-260ºC)
 Silicone rubber   (ambient temperature range 0-180ºC)
Jacket layer materials: fiberglass, PVC, PFA, silicone rubber
Galvanized layer: stainless steel, tinned brass

3.Standard: conforms to IEC584 standard.
