Seismically Certified SF6 Insulated Switches

G&W offers wide variety of seismically certified SF6 insulated switches for pad mount and vault applications.  The switches feature dead front construction to eliminate exposure to live parts, and they require no maintenance due to their hermetically sealed construction.  Switches are rated for use in 3-phase 15kV, 25kV, and 35kV systems with continuous current ratings of 630A and 900A.  Optional over current protection to 25kA symmetrical is also available.  Designs for pad mount, vault, and equipment room installations are available with manual switch operators and bushings on the front (front access) or manual switch operators on the front and bushings out the bottom (bottom access).  All designs include load break switches with a visible open of all 3-phase phases to increase operator safety.

The switches are designed per the guidelines of ASCE (American Society of Civil Engineers) standard 7-05 Chapter 13.  These guidelines cover the design of non structural components installed in a building.  The switches also underwent a test regime specified by ICC-ES-AC-156 (International Code Council Evaluation Services Acceptance Criteria) which specifies the shaker table test inputs applied to the switches.

G&W SF6 switches has been time proven for nearly 40 years.  They will provide decades of reliable service for applications covering line sectionalizing, loop switches, and transformer protection.
