Power grid
Small cables carry 10 kW, large ones 250 kW; a transformer joins them into one grid that can feed heavy industry.
In the game
How to get it
Build a transformer, plug small power cables on one side and large ones on the other, and set it Up or Down on its sheet.
What it is for
Bring the power of many generators, turbines and panels onto one large cable: the hyperbaric press asks up to 200 kW, more than twenty small cables.
Why it exists
Heavy industry needs power from far away. A grid is the step from a powered workshop to an industrial site.
The same text the game shows in its progress tree and on the item's sheet (I).
The goal Power grid is reached with your first Transformer: the moment small and large cables meet.
How to do it
1. Lay a large power cable from your plant to where the heavy machines will stand. 2. At each end, a transformer: Up from the small cables of your generators to the large line, Down at the other end to the small cables of ordinary machines. 3. Big consumers plug straight on the large line.
Orders of size
| Power | |
|---|---|
| A lamp | 25 to 150 W |
| The metal mill, the refinery (on a cable) | 3 kW |
| The gas plant | 6 to 9 kW |
| The Furnace making aluminium | 8 kW |
| The hyperbaric press | 30 to 200 kW |
Why it exists
The alloys' press is the first machine no small cable can feed: it pushes the player to build a real plant and carry its power.
