Gold Cable

The Gold Cable is the Tier 2 cable. They suffer higher distance-related energy losses than Copper Cables, but are able to carry Medium Voltage, up to 128 EU/tick. Gold cables have 2 different levels of insulation, with the 2x insulation providing smaller losses per tile and less shock damage from high voltage.

It's worth noting that even though gold cables have a higher energy loss per packet, this is countered by the fact that the maximum packet size for gold cables is 4 times that of copper cables. For example, if you send 128 EU/tick through 4 tiles using Copper Cables, you will have 4 packets of 32 EU/tick, and each of those will suffer a 1 EU/tick loss, resulting in 124 EU/tick reaching its destination. If Gold Cables are used, that 128 EU/tick will be sent in a single packet, that will suffer a 2 EU/tick loss, resulting in a final 126 EU/tick. For this reason, it is recommended to use transformers to elevate the voltage when transferring power through long distances.
