Vandenberg – XUMU 12-1267B – Replace 12 KV Switchgear at Substation B – Bldg 7315
Vandenberg AFB, CA

Schwab Engineering has provided professional engineering services to replace 12kV switchgear at Substation B, Bldg. 7315. The existing 12KV switchgear is a triple ended switchgear with two (2) tie breakers consisting of fourteen (14) vertical sections.

The new 12KV switchgear will be manufactured and assembled with the same number of vertical sections and same number of breakers, spare and space to match the existing switchgear. Control power for the new switchgear will be 125V DC from the existing station batteries with charger for closing and tripping of the breakers.

The new switchgear will have an infrared window at each rear door to allow the VAFB personnel to complete a thermal inspection of the switchgear without opening doors. The new 12KV switchgear will be manufactured and assembled to comply with ANSI Standards, IEEE, U.L., IBC/CBC Seismic and the California Code.
