HV Cable

HV cables are the highest tier conventional cables. They can tolerate High Voltage (512 EU/p) and Extreme Voltage (2048 EU/p), but have an extremely high distance-related energy loss. HV cables can have 3 different levels of insulation. Considering that a shock from a poorly insulated HV cable will most likely prove fatal, it is recommended to insulate them well unless the cable is located in a completely unreachable area. Even then, insulation should be applied to reduce the massive energy losses.

Uninsulated and powered HV cable can also be used as a defensive measures as mobs and potentially unwanted players easily get killed if not or

poorly protected.((you have to make sure there is power traveling instie the cables just seting these and fill up a mfsu wont work you have to set somting thats using electriceti to (like mass fabricator))

Although in-game it currently lists "4xInsulated", that is incorrect as you are adding a layer of insulation each time, not doubling the insulation each time. It is actually "3xIns" and should get renamed eventually in some future patch.

It's also worth noting that, despite of the massive capacity of these cables, they are actually cheap to craft, since they are made of Iron, a very common mineral.
