150m ignition wire?

We have a burn pit. The ignition panel is 150 meters away. A transformer converts 220v to 20000v and sends it to ignitor at the pit. What kind of wire can be used here? We need two for thermocouple, one for 20Kv phase and one for null. I need to know the exact type and whether I can use ordinary wires in this case.

The insulation has to be rated for the application. I've used solid core spark plug wire for this application. If this is going to a spark plug, make sure you run a conductor back to the source for the return path. Is this a thermal oxidizer unit?
