The '''Cables''' are the primary means of transferring [[EU]] from one device to another. There are several different types of cable, each type made from different metals, and each type can tolerate a different maximum [[EU#EU-Packet|EUP]]. If too high of an EUP is applied to a cable, it will instantly melt. Cables can handle unlimited amounts of total ([[EU|EU/t]]).

All cables suffer from energy losses over distance. Long cables will lose energy in the process of transferring it. There are several ways to reduce losses - Transformers , insulation, and daisy-chaining storage devices. Insulation also reduces the amount of shock damage the player and NPC's receive from touching high EUP cables.

Tin cables can only tolerate '''Micro Voltage''' (up to 5 [[EU|EUP]]) but they're very cheap to make and have extremely low energy loss.
In the most recent versions of IC2, [[Tin Cable]] can tolerate '''Low Voltage''' (up to 32 [[EU/p]]), which means they can handle the energy outputted by basic Generators, but they're very cheap to make and have relatively low energy loss (0.20 EU/block).
 
In older versions, Tin cables could only tolerate '''Micro Voltage''' (up to 5 [[EU/p]]).  Since no transformer can "step down" voltage this low, Tin cables were only suited for lower-output generators like [[Solar Panel]]s, [[Water Mill]]s, or [[Wind Mill]]s.

Copper cables are the most common cable tier. They are only capable of handling '''Low Voltage''' (up to 32 [[EU|EUP]]), however, they suffer the smallest distance-related energy losses out of all the conventional cables, with insulated copper cables having even less energy losses.
In the most recent versions of IC2, [[Copper Cable]] are the most common cable tier. They are only capable of handling '''Medium Voltage''' (up to 128 [[EU|EUP]]), however, they suffer the second smallest, distance-related energy losses out of all the conventional cables (same as tin cables, 0.20 EU/block).
In older versions, they were only able to handle '''Low Voltage''' (up to 32 [[EU|EUP]])

Gold cables can transport '''Medium Voltage''' (up to 128 [[EU|EUP]]) but has higher energy loss than copper. The loss can be remedied to some extent by giving the cable up to two layers of insulation.
In the most recent versions of IC2, [[Gold Cable]]s can transport '''High Voltage''' (up to 512 [[EU/p]]) but has higher energy loss than copper (0.40 EU/block) However, since the energy loss applies to each package of energy, if carrying full 512EU/p, the gold cable will lose less energy than copper over distance, see below for more information.
In older versions, they could only transport '''Medium Voltage''' (up to 128 [[EU/p]]).

HV Cables can handle the highest amount of current possible at '''Extreme Voltage''' (up to 2048 [[EU|EUP]]) however it loses energy very quickly and should only be used when there's no other choice. HV cables can have up to three layers of insulation to help deal with the energy loss.

All cables suffer distance-related energy losses, and depending on the tier and insulation of the given cable, the losses can vary greatly. The general unit for cable efficiency is EU/block. It shows how much [[EU]] every [[EU#EU-Packet / Voltage|EU Packet]] looses per block. The number is accumulated along the whole length of the cable, and then rounded down to the nearest integer. Therefore, if a distance is short enough, there EU loss will remain zero. For example, since Copper Cable loses 1 EU every 5 blocks, a 4 block long Insulated Copper Cable won't lose any EU.

Depending on the [[EU|EUP]] traveling trough a cable it may be more efficient to use higher voltage cables and packets. This is because EU/b isn't applied on the total [[EU#EU/t|EU/t]] that travels the cable but on every single [[EU#EU-Packet|EU-Packet]].
 
So a copper cable carrying 320 EU/t over 10 Blocks of insulated copper cable is really carrying 10*32 EU-Packets and instead of: 320EU-2EU=318EU you get: 32EU*10-2*10=300EU. But when using 512 EU-Packets and 2x insulated gold cables you get: 320EU-4EU=316EU. In this example this is a difference of 16 EU over 10 Blocks.
Depending on the [[EU/p]] traveling through a cable it may be more efficient to use higher voltage cables and packets. This is because EU/b isn't applied on the total [[EU/t]] that travels the cable but on every single [[EU/p|EU-Packet]].
So an insulated copper cable carrying 384 EU/t over 10 Blocks is actually carrying 12*32 EU-Packets and instead of: 384EU-2EU=382EU you get: 32EU*12-2*12=360EU. But when using 128 EU-Packets and [[2x Insulated Gold Cable]]s you get: 128EU*3-4*3=372EU. In this example this is a difference of 12 EU over 10 Blocks.  
 
What can be concluded from a cursory glance over the numbers is that, when using maximum allowable voltage, Copper cables are actually the most lossy cable type (at 25.0% per 40 blocks), followed by Tin (at 20.0% per 40 blocks), then Gold (at 12.5% per 40 blocks), then Iron (at 1.56% per 40 blocks), and the most lossless is Glass Fibre (at 0.195% per 40 blocks).

Experimental-Only Content: This information has been updated to the V2.X version of IC².
The most recent version of IC² is V2.8.<html>.

The Cables are the primary means of transferring EU from one device to another. There are several different types of cable, each type made from different metals, and each type can tolerate a different maximum EU/p, usually referred to as Voltage. If an applied Voltage exceeds a cable's maximum, the cable will instantly melt. This is NOT to be confused with (EU/t), usually referred to as Current; all cables can handle an infinite amount of current.

All cables suffer from energy losses over distance. Long cables will lose energy in the process of transferring it. There are several ways to reduce losses - Transformers , insulation, and daisy-chaining storage devices.

Uninsulated cables damage all entities that comes near the cable when there is EU flowing through the cable. An uninsulated HV cable with a current of 2048 EU/t can kill a player fully equipped with fully charged Quantum Suit within 20.5 seconds. The higher the voltage, the more damage a cable can inflict on entities.

Insulating cables with rubber reduces energy losses, reduces shocks, and allows the cable to be painted using the Painter. Painted cables will not connect to different colored cables. This also greatly reduces the strain on CPU, as large cable meshes with many intersections require the game to perform many CPU-heavy calculations.

The Splitter Cable is a special cable which prevents EU from flowing through it when a redstone current is applied. They can handle up to 2048 EU/p.

Cable Efficiency[edit]

All cables suffer distance-related energy losses, and depending on the tier and insulation of the given cable, the losses can vary greatly. The general unit for cable efficiency is EU/block. It shows how much EU every EU Packet loses per block. The number is accumulated along the whole length of the cable, and then rounded down to the nearest integer. Therefore, if a distance is short enough, there will be no EU loss. For example, since Copper Cable loses 1 EU every 5 blocks, a 4 block long Insulated Copper Cable won't lose any EU.

Tin Cable Copper Cable Gold Cable HV Cable Glass Fibre Cable Detector / Splitter Cable
EU/b EU loss EU/b EU loss EU/b EU loss EU/b EU loss EU/b EU loss EU/b EU loss
Uninsulated 0.025 1 EU every 40 blocks 0.3 1 EU every 3.33 blocks 0.5 1 EU every 2 blocks 1.0 1 EU every block 0.025 1 EU every 40 blocks 0.5 1 EU every 2 blocks
Insulated (1") --- 0.2 1 EU every 5 blocks 0.45 1 EU every 2.22 blocks 0.95 1 EU every 1.05 blocks --- ---
Insulated (2") --- --- 0.4 1 EU every 2.5 blocks 0.9 1 EU every 1.11 blocks --- ---
Insulated (3") --- --- --- 0.8 1 EU every 1.25 blocks --- ---

Voltage Efficiency[edit]

Depending on the EU/p traveling through a cable it may be more efficient to use higher voltage cables and packets. This is because EU/b isn't applied on the total EU/t that travels the cable but on every single EU-Packet. So an insulated copper cable carrying 384 EU/t over 10 Blocks is actually carrying 12*32 EU-Packets and instead of: 384EU-2EU=382EU you get: 32EU*12-2*12=360EU. But when using 128 EU-Packets and 2x Insulated Gold Cables you get: 128EU*3-4*3=372EU. In this example this is a difference of 12 EU over 10 Blocks.

What can be concluded from a cursory glance over the numbers is that, when using maximum allowable voltage, Copper cables are actually the most lossy cable type (at 25.0% per 40 blocks), followed by Tin (at 20.0% per 40 blocks), then Gold (at 12.5% per 40 blocks), then Iron (at 1.56% per 40 blocks), and the most lossless is Glass Fibre (at 0.195% per 40 blocks). Remember, these values only apply if current is passed at the highest voltage available for that cable type.

The formula for overall EU/b is: Combined EU/t divided by Desired packet size multiplied by Cable's EU/b per Packet equals Combined EU/b

Below is an example of different EU/t packed into different EU-Packets and carried with different cables, cables are full insulated, EU-P equals EU-Packet, results are in Overall / Combined EU/b (not EU/b per Packet), results can't be rounded down to nearest integer.

  • Blue color indicates that EU-Packets under 32 EU can't be obtained by transforming. They can only be generated with generators as they always emit EU-Packages the size of their output EU.
  • Green color indicates the optimal EU-Package for that EU/t example. Blue fields are ignored.
  • Orange color and red color indicates sub-optimal EU-Packages.

Cable Splitting[edit]

Up to 4 cables can connect to one cable. Current will only flow through a cable when requested by a consumer if the loss from the cable length will allow some energy to get to the consumer. i.e. a Batbox (32EU) will send across insulated copper to a furnace up to 155 blocks away (5x31). No energy will be sent to anything 156 blocks away.

Keep in mind, however, that an excessive number of cable intersections will increase strain on your CPU (and more importantly, the server, when playing on a multi-player server). Don't do things like having rows of adjacent cables with every block connected to every other block. Also, separate cables connected to an energy storage device (BatBox, etc.) or transformer do not count as a cable intersection, so take advantage of that when possible.
