59 -- PULSE TRANSFORMERS FOR HVDC CONVERTER STATION SOL DE-RQ-65-98-WE-06055 DUE 042598 POC Holly W. Kittleson (406)526-3423 The Western Area Power Administration (Western), Montana Maintenance Office, intends to acquire, on a SOLE SOURCE basis, twenty five (25) pulse transformer assemblies from Power Products, Inc. Western intends to solicit one source under authority of FAR 13.106.2(a)(5), which authorizes contracting without providing for full and open competition when only one source is reasonable available. The pulse transformer assemblies are an integral part of the Miles City HVDC converter's valve firing system which was designed and built by General Electric (GE). The assemblies distribute the pulse produced by the gate drive units necessary to fire four thyristor voltage levels on a valve module. There are two pulse transformers per assembly. They were designed and built by GE to meet specific electrical criteria along with the ability to fasten directly in the GE valve modules. Power Products, Inc. is the only known source that has the proprietary engineering specifications and drawings necessary to manufacture these specialized transformer assemblies. Anticipated award date is April 27, 1998. This notice is not a request for quotes. However, interested parties may identify their written interest and capability to satisfy the Government by faxing the CO at 406-232-8500. Capability statements must provide documentation of the capability of manufacturing a direct replacement for the pulse transformers utilized at the Miles City HVDC Converter Station. See Note 1.
