Heavi-Watt Joint Plate

The Heavi-Watt Joint Plate allows Heavi-Watt Wire to pass through walls without letting gas or liquid leak through. It serves the same basic function as a wall penetration for power lines, making it possible to route high-capacity wiring between sealed rooms, shaft spaces, and other enclosed areas without breaking the barrier.

Unlike the wire itself, the tile portion of the Joint Plate is not connected to power, so it can be crossed by ordinary Wire. This makes it useful as a bridge in layouts where standard wiring needs to pass through the same location as a Heavi-Watt line. The plate also preserves wall integrity for gases and liquids, so it is commonly used anywhere a power grid must cross a sealed chamber.

There is one important drawback: the Joint Plate conducts heat significantly. If it is built through an Insulated Tile wall, it can still leak a noticeable amount of heat into the surrounding area. In heat-sensitive builds, it is often best to construct the plate from Gold Amalgam and keep it out of contact with liquids. If necessary, a vacuum seal can be used around the plate to fully isolate it thermally.

• Use the Joint Plate whenever a Heavi-Watt Wire must pass through a wall without opening the room to gas or liquid flow.
• The center tile is not powered, so regular Wire can pass through it.
• Avoid placing it in insulating walls if the surrounding area must remain thermally stable.
• Gold Amalgam reduces the thermal impact compared with less suitable materials.
• Keeping the plate dry helps limit heat transfer.
• In extreme builds, surrounding the plate with vacuum provides the strongest insulation.

It is especially valuable in compact power networks, vertical shaft designs, and late-game bases where large electrical loads must be moved through separated rooms.
