AI Overview
The Siemens NXAirS LP (Low Power) is a metal-enclosed, air-insulated medium-voltage switchgear designed for high reliability, safety, and corrosion resistance. It is part of the broader NXAIR family, featuring a compact design suitable for critical infrastructure, including data centers, marine/harbor applications, and new energy storage systems.
Key Corrosion-Resistant & Structural Features
- High-Strength Materials: The frame is constructed from corrosion-resistant Aluminum-Zinc (Al-Zn) plated steel plates.
Technical Specifications & Capabilities
- Voltage and Current Ratings: Up to 12 kV, 4000 A (busbar), and 40 kA (short-circuit rating).
- Dimensions: Features a compact design, such as the 550mm width per panel in the 550+ series.
- Standards: Type-tested according to IEC 62271-200 and GB3906 standards.
- Sustainability: Uses natural air as an insulating medium, eliminating greenhouse gases.
Safety and Operational Features
- Internal Arc Classification (IAC): Tested to IAC A FLR (Front, Lateral, Rear) for safety, typically for 1s.
- Interlocking: All switching operations are performed with the high-voltage door closed.
- Maintenance: Employs maintenance-free 3AE vacuum circuit-breakers.
- Digitalization: Supports Low Power Instrument Transformers (LPITs) and SIPROTEC 5 protection relays.
Daqo Intelligent Electric is a Siemens-certified manufacturer for the NXAirS LP, producing units that meet these specifications.
If you're looking to select the right switchgear, let me know:
- What is the voltage requirement (12kV, 24kV, etc.)?
- What is the application (data center, marine, industrial)?
- Are you interested in the digital/LPIT features?
I can provide more tailored technical data based on your specific needs.
