automation wires destroyed by rocket ignition

Try Tungsten. Automation wire have small weight, and very very fast heating.

5 kg - automation wire

100 kg - heavy-watt wire

25 kg - wire

Tungsten have high melting point.

Don't build meltable things below rocket exhaust.

Honestly. I understand that it could be hard to manage the linear heat of the rocket in the game code.

But I have 2 layers and vacuum between the exhaust and the automation wire.

It should not heat that much.

With the vaccum, the second layer should not even take 1°C, because the first layer stops the gas.

Thanks. I don't remerber it was better than the thermium that is not really better than steel despite its overheat value

The heat bypasses layers. It is applied directly to tiles.

You could also try embedding the wires in the tiles, since heat is only applied to the tile itself and not to buildings in it. The 400kg insulated tile is unlikely to reach temperatures high enough to melt steel.

The reason the heavi-watt wire didn't melt is that it has higher mass. The heating affects gases more strongly because it "adds heat", not exchanges temperature.
