Instrumentation Cable is a single or multi-pair cable designed to carry signals. Used for connecting instruments and electrical equipment in process control.
Control cable is a multi-conductor cable used for operation in control circuits, to connect electric/electronic equipments. It is generally used to carry out “on/off” controlling signals like start/stop command.
Power cable is typically constructed with five conductors and used for transmission of electrical power.

Thermocouple cable is required to make the connection between the thermocouple and the measuring instrument. The construction is totally similar to the Instrument cables a part the material of the conductors. Thermocouple Extension cables use the same alloys as the thermocouple. Compensating cables use different alloys which have a matched emf output over the appropriate temperature range. The Extension cables are more accurate but more expensive than Compensating.
