SECTION 1 - WESTERN AREA POWER ADMINISTRATION (WAPA) BUSHING SPECIFICATION

1.1 GENERAL:

A single bushing for a 550-kV power circuit breaker located at Tracy Substation sustained damage. The replacement bushing shall be composite, shall be manufactured/provided by Siemens and shall conform to the latest IEEE C37.017-2020 Bushings for High-Voltage (Over 1000 Vac) Circuit Breakers and Gas- Insulated Switchgear. The bushing and adapters shall be direct replacement for Tracy Substation 550-kV power circuit breaker SPS2-550kV-63-1. If the Government exercises the Optional Contract Line Item as described below in Section 3, the contractor shall have Siemens perform the work to replace the existing bushing with the new bushing and make all connections and preform all tests required to place the unit back into service. The Government intends to exercise this Optional Line Item if at time of bushing delivery construction is complete and no construction crew is available on site to install the bushing.

Bushing shall be composite. Composite type bushing shall consist of a core, housing, top mounting plate, bottom mounting plate, end fittings, flange cover assembly, guide pins, and all accessories as required to install the bushing on the existing Siemens power circuit breaker. The outer material shall resist formation of electrical tracking on the surface of the insulating material, resist cracking, prevent hydrolysis (chemical process leading to electrical or mechanical degradation), have electrical and mechanical characteristics as required for the application, provide the necessary creep distance, shall have a life comparable to what a porcelain bushing provides and withstand sunlight for the entire life of the equipment (resist ultra-violet radiation and pollution).

1.2 SERVICE CONDITIONS:

The Bushings shall be suitable for operation under the conditions as listed below in the following subsequent stated requirements:

a. Ambient Temperatures:

Maximum +50 oC Maximum 24-Hour Average +35 oC Minimum -30 oC

b. Minimum Elevation Rating:

Above Mean Sea Level 3,300 ft

c. ASCE-7 Wind Load:

Minimum Basic Wind Speed 100-MPH Importance Factor 1.15

d. IEEE 693:

Seismic Qualification High

e. Agricultural Pollution/Contamination:
