Power-Duct™ Non-Segregated Phase Bus Duct

Characteristic:

Typical Power-Duct Bus Duct to Equipment Transition

Description

The non-segregated phase bus duct is an assembly of bus conductors without inter-phase barriers. All of the associated connections, joints and insulating supports are contained within a metal enclosure.

Siemens Power-Duct non-segregated phase bus duct is designed for 600 V, 5 kV and 15 kV service in accordance with ANSI/IEEE C37.23. Continuous current ratings available include 1,200 A to 3,000 A for 5 kV through 15 kV and 1,200 A to 4,000 A for 600 V.

All conductors are separated and isolated from each other by insulating bus supports.

Every conductor for 2.4 kV and above is insulated with an epoxy coating to reduce corona and electrical tracking.

Multiple enclosure sizes are available to meet your specific requirements. Low-voltage application dimensions available:

• 14" (356 mm) x 21" (533 mm) (1,200 A-3,000 A)
• 16" (406 mm) x 31" (787 mm) (4,000 A).

Medium-voltage application dimensions available:

• 12" (305 mm) x 24" (610 mm)(1,200 A ND (narrow design)
• 16" (406 mm) x 33" (838 mm)(1,200 A-3,000 A).
