TYPE T (Copper vs Constantan) is used or service in oxidizing, inert or reducing atmospheres or in vacuum. It is highly resistant to corrosion from atmospheric moisture and condensation and exhibits high stability at low temperatures. It is the only type with limits of error guaranteed for cryogenic temperatures.

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.
