Wetown provides non-segregated phase bus systems for power generation and industrial power distribution applications. NSPB is a practical enclosed bus solution for projects that require reliable electrical performance, compact structure, and flexible engineering design.
What Is Non-Segregated Phase Bus?
Non-segregated phase bus, or NSPB, is a type of metal-enclosed bus system in which multiple phase conductors are installed within a shared enclosure space or in a less isolated arrangement than IPB.
Typical Applications
- Auxiliary transformer connections
- Medium-voltage distribution systems
- Power plant auxiliary circuits
- Industrial power distribution networks
- Substation bus connections
- Utility and infrastructure power projects
Key Features
Compact structure
NSPB offers a space-saving enclosed design that helps simplify routing and installation in electrical rooms, substations, and plant auxiliary systems.
Reliable electrical insulation
The system is designed to maintain insulation performance under normal industrial operating conditions and can be adapted for different environmental requirements.
Flexible engineering arrangement
Wetown can customize the bus layout, connection interfaces, support structures, and installation configuration based on the project design.
NSPB vs IPB
| Item | NSPB | IPB |
|---|---|---|
| Structure | Multiple phases in a shared / less isolated enclosure arrangement | Each phase in a separate enclosure |
| Typical Use | Auxiliary power and medium-voltage distribution | Generator outlet circuits and larger power plant connections |
| Space Requirement | More compact | Larger installation space |
| Typical Current Level | Medium to high, depending on design | High current applications |
Selection Notes
NSPB is commonly a strong choice when the project requires a compact enclosed bus structure, reliable medium-voltage or auxiliary power distribution, reduced installation space, and flexible connection to auxiliary electrical equipment.
