Cnt 20121201 | Technology | Energy And Resource· Politicians are for Mom, the flag, apple pie and babies, too. But they generally don't have to put their money where their mouths are. Manufacturing in the United States has been written off as a dead issue ever since the 1990s, when companies started closing plants and offshoring jobs to "low-cost countries" such as China. Well, China isn't so low-cost, now.

Switchgear - Wikipedia for lower voltages may be entirely enclosed within a building. For higher voltages (over about 66 kV), switchgear is typically mounted outdoors and insulated by air, although this requires a large amount of space. Gas-insulated switchgear saves space compared with air-insulated equipment, although the equipment cost is higher.
