Cable Splitting / Branching
Branching a cable is like Branching a river's power. The more you branch, the less each end get the power (EU/f).
You can only split to TWO cable at a time, and if you want to split up to three or more, you need to split it as a branch of a branch.
In most case (No relay), the total energy in the system will be conserved.
Power IS NOT Energy. Think of it like Power is the muscle strength, and energy is the sugar.
This is what happen to the power inside a branched cable: 
The power distribution is still valid EVEN IF one of the branch is empty branch (no machine, no MFE or MFSU, just one block cable extended).
But do not worry, in the case of empty branch , the only thing happen to the energy is simply slowing down the energy transfer rate by half, no energy loss, just slower.
In case of a complex cable switch which involve two separate input and more than 2 separate output, the calculation can be done as if each input is independent of other input, but later superimposed. 
To wire a row of machines to an output, the split distribution rule is still valid. Each machine attached to the cable will be considered as a split/branch. Eventhough the machine is off, a branch is still a branch. The next machine will only get half of the power that the previous machine get even though no machine is on. 
In order to have an efficiency power allocation, make sure that all machines are plugged in a way that the machine's continuous consumption is less or equal to the power it can obtained from the cables.
For example in the picture, recycler use minimum of 1 EU/f for continuous operation. If the MFE/MFSU output it set at 32 EU/f , recycler can be attached as first to fifth machines. But power hungry electro furnace need minimum of 3 EU/f for continuous operation, there for, you can only attach it as first to third machines if you want a smooth smelting/furnacing.
Multiple Output Cable Switch/Selection
Let's say that you have 4 different direction you want to direct your power to, but you want to allow one or two direction at a time to get the maximum power you can give with minimum split, there is one easy trick: sticky pistons. 
The idea of using sticky pistons is to transform a power connection from a branched cable to non-branched cable.
Using Switch cable can be useful however, the power branch might reduce the power so low that you cannot work with it anymore,
because branched connection with switch cable still count as branched cable EVEN IF there is no connection.
A non-pulsing High Voltage connection
ATTENTION: High Voltage cabling is highly dangerous. Once the system is setup, touching a live wire is essentially an instant death.
This information focuses on the huge energy transfer with HV-transformers as repeaters , zero energy loss for Mass Fabricator ONLY.
In order to achieve a constant 2000 EU/f power transfer, there is only 1 simple requirement: 2000 EU/f Low/Medium Voltage TOTAL input to the FIRST HV transformer.
Experiments have been done regarding adding powers into subsequent HV transformers, and the results show that the total output has an average 600-1000 EU/f instead of 2000 EU/f as inputted into the system.
Distributed Energy Generation , Energy Storage and Energy Consumption Using HV Ring method
First, what is HV ring? HV ring is a setup of HV Transformer in a circular pattern, in a small distance between each transformer to prevent energy loss through cable resistance.
The bigger the 'complex', the bigger the ring need to be to connect all of them in a circular pattern. Each 'HV transfo station' will be able to contribute or use the shared energy in the system.
For energy generation, energy can be inputted into the ring by connecting the generators to one of the HV transfo 'station' as input.
For energy storage, the energy will be 'sap' from a split in the ring to a set of capacitors. The Capacitor outputs will be connected back to the right 1 HV transfo station away from the initial split.
For energy consumption, use the same split as the energy storage.
Theoretically, all energy is conserved, but it is possible that at certain point, the HV ring is over-saturated with power momentarily, and a small capacitors at each energy generation station is suggested.
ATTENTION , each HV ring can efficiently handle energy transaction at the maximum approved performance of 1000 EU/f. It is theoretically not possible to achieve 2000 EU/f energy transfer without complex arrangement. However, it is allowable and possible to have multiple HV ring connected to each other in parallel to increase energy transfer performance.
