Stronger Conduit Variant and or Buried Conduits

[Draegon]

I have noticed that conduits get broken incredibly easily and since power generation often requires long lines of conduits (looking at you geothermal) it would make sense to have a stronger variant or one that's buried where attackers/fire cannot get to them. The stronger variant could be more expensive or require some small research. The buried version would be the same cost but require more work plus it would be invisible to attackers or would be targeted far less. I also find it rather odd that attackers can just punch a conduit a bunch of times to break it (I mean really, punching a power cable is unlikely to do much to it).
