1000℃ KX-VS-VS-0.81 Vitreous Silica Insulated Thermocouple Cable Type K Wire
Thermocouple Wire and Cable Know-How
For the extension/compensation cable, the basic structure is conductor and insulation.
To increase its temperature bearing ability and to install easily, jacket is applicable.
In the working environment, there are too much factors will interference the EMF signal, therefore shield layer is practical way to prevent the cable from interference caused by complex environment.
