About this file
This document is a product specification sheet for a Primary Switching Center (PSC) manufactured by PD Power Systems, LLC. The PSC is a 5kV medium voltage generator power distribution and isolation unit that uses load-interrupter switches and vacuum fault interrupters for switching 600A IEEE-386 Deadbreak connectors. The PSC has six individual three-phase disconnects, with four of the six protected by a microprocessor-based overcurrent controller. The PSC has dimensions of 104" L x 72" W x 48" H and weighs 4,800 lbs. It is rated for 12,000VAC 600A at 50Hz and 15,500VAC 600A at 60Hz.
The related federal contract opportunity is for the construction of a primary power project/feeder on the north side of Chabelley Airfield in Djibouti. The solicitation number is FA542224R0007, with offers due on the date listed in the solicitation. A site visit is scheduled for 18 July 2024. All offerors must be registered in the Joint Contingency Contracting System (JCCS) and have an "Acceptable" status in order to be eligible for award.

Capabilities and Features
The Primary Switching Center (PSC) provides for the distribution and safe isolation of the power output of 5kV medium voltage generators. The main component of the PSC is the internal S&C Vista Switch. The Vista Switch is enclosed within a housing that provides environmental proection and operator safety. Additionally, the design of the enclosure permits two PSCs to be stacked within a shipping frame for transportation and/or storage.

The PSC uses load-interrupter switches and vacuum fault interrupters for switching 600 amp IEEE-386 Deadbreak connectors. Four of the six connections are protected using a microprocessor-based overcurrent controller, which is reconfigurable and resettable.
The load-interrupter switches are three-position (closed-open-grounded), manually operated disconnect switches, each providing three-pole switching to isolate associated 600A Deadbreak connection points. The fault interrupters are the same style load interrupters (closed-open-grounded) with the addition of vacuum connected in series. A built-in voltage indicator is located under the viewing window for each disconnect. The indicator is isolated from the main 5kV voltage and uses a solar powered source to indicate the presence of voltage.
The PSC features six (6) individual three-phase disconnects. Each connection point, referred to as a Ways, is rated for 600 amps and all are bussed together on one side. Each 600A connection point is an IEEE-386 Deadbreak. All power connections in or out of the PSC are through either 600A Deadbreak or 200A loadbreak connections.
