1.0SCOPE
This specification covers the design, manufacture, and testing of three pole, gang operated vertical interrupter outdoor circuit switchers without integral disconnect.
2.0STANDARDS
All outdoor circuit switchers shall be designed, manufactured, assembled, and tested in accordance with the latest applicable ANSI, NEMA, and ASTM standards and guidelines. If there are any conflicts between the ANSI, NEMA, or ASTM standards and this specification the specification shall govern.
3.0DESIGN REQUIREMENTS
3.01Service Conditions
The circuit switcher shall be suitable for outdoor installation in electric power substations under the following conditions:
3.01.01Temperature
The circuit switcher shall perform in an ambient temperature range of -40oC through +50oC.
3.01.02Altitude
The circuit switcher shall perform at elevations up to 3,300 feet.
3.01.03Seismic
The circuit switcher shall be capable of withstanding seismic loading of 0.2 g ground acceleration in any direction when installed on the manufacturer’s furnished support structure and anchor bolts and with flexible connections to the terminal pads. The circuit switcher shall perform its specified functions during and after the seismic event.
3.01.04Wind Loading
The circuit switcher shall be capable of withstanding wind loads up to 90 mph without loss of function.
3.01.05Additional Requirements
If any site specific service conditions not covered in sections 3.01.01 through 3.01.04 exists (e.g. extreme cold temperature installation, corrosive environment, high altitude installation, etc.) they will be defined in the quotation request.
