The voltage is always determined by the device. (in this case a slow cooker).
However, having established what voltage to supply to the device, the cable must be suitable for the voltage used. Everything in the chain of power transmission, must be rated for the correct voltage. Cables, plugs, fuses etc.
Cable
To answer this question the voltage of the cooker is needed.
The thermocouple is an sesnsing device , when the temperature increases it increases the voltage , that voltage is used for tripping purpose
A cable tester is used to test the electrical connections in a cable or other wired device. There are two ways to test for a connection: continuity test and resistance test. A cable tester can also test for a short by determining voltage.
There is actually no specific formula used to work out cable size. In order to determine the type of cable you need and the size you need, you need to know the source of the supply, the voltage of the system, the ambient temperature, and the method you plan on laying out the cable.
Voltage Grade of cables specifies the safe voltages which the insulation of the cable can withstand.

More electricity needed by a cooker requires a thicker cable than for a table lamp.
I assume you mean a cooker switch, which should be fed from a 40A MCB in the conmsumer unit and with 6mm cable

An electric cooker cable is designed to handle higher power loads and is typically thicker and more robust compared to a bulb cable which is thinner and designed for lower power applications like lighting. Additionally, an electric cooker cable may have different connectors and insulation ratings as it is meant for higher temperature environments.
If the voltage is supplying any current through the cable, i.e. if there is any 'load' at the end, then the voltage will drop through the cable.
It will decrease the voltage drop.
To calculate the cable size for a 30-meter run, you need to consider the current rating of the circuit, voltage drop limits, and the type of cable insulation. Use a cable sizing calculator or consult a professional electrician to determine the appropriate cable size to ensure safety and efficiency of the electrical installation.

An LT cable is a low tension (or low voltage) cable.
