However The Copper Cable is the Tier 1 Cable and the most common. They are only capable of handling Low Voltage (up to 32 EU/t), however, they suffer the third smallest distance-related energy losses out of all the conventional cables, the numbers 1 and 2 being Glass Fibre Cables and Tin Cables, respectively. When you insulate the copper cables, it suffers even less. Unlike Gold Cable and HV Cable, they can be only insulated once. They are also used in the creation of Electronic Circuits, a very common building item in machines. But be careful uninsulated wire can shock the player causing damage. To prevent that damage use Rubber Boots.
|Cable type||EU/b||Energy loss|
|Copper Uninsulated||~0.3||1 EU per 3.33 blocks|
|Copper Insulated||0.2||1 EU per 5 blocks|
