Medium-voltage power distribution is a critical part of modern industrial facilities, commercial complexes, infrastructure systems, renewable energy stations, and public utility projects. As electrical loads continue to increase, customers need a medium-voltage switchgear system that can provide high safety, stable operation, compact installation, flexible configuration, and reliable fault protection.
For this project plan case, the customer required a medium-voltage power distribution solution for a new industrial power supply system. The project included incoming power control, feeder distribution, transformer protection, metering, monitoring, and future expansion requirements. To meet these needs, GAOBO SWITCHGEAR MANUFACTURER proposed a customized Siemens NXAirs LP Medium Voltage Switchgear Cabinet solution.
NXAirs LP is a new type of medium-voltage metal-enclosed switchgear designed by Siemens. It is positioned as a unified medium-voltage power distribution solution tailored to customer requirements, with advantages in safety, reliability, flexibility, compact design, and air-insulated structure. GAOBO Power Solution has obtained production authorization for Siemens NXAirs LP medium-voltage switch cabinets.
The customer planned to build a reliable medium-voltage distribution room for industrial production and facility power management. The system needed to support stable power supply for transformers, production lines, motors, auxiliary equipment, HVAC systems, lighting, and building service loads.
The main requirements included:
GAOBO proposed a customized Siemens NXAirs LP Medium Voltage Switchgear Cabinet solution based on the customer’s project drawings, power supply requirements, rated current, short-circuit capacity, installation space, and operating environment.
The switchgear lineup was designed as a complete medium-voltage distribution system, including:
The product page highlights that NXAirs LP provides exceptional safety, reliability, and flexibility, and that Siemens works with qualified medium-voltage switchgear manufacturers that meet Siemens standards as technology partners for this type of air-insulated switchgear.
For this project, the switchgear configuration was selected according to the customer’s actual load demand and local grid conditions.
Main technical parameters included:
The NXAirs LP switchgear solution was selected because it matched the project’s requirements for safety, flexibility, compactness, and reliable operation.
1. Safe and Reliable Operation
The switchgear is verified by complete type testing, helping ensure stable operation in medium-voltage distribution systems. For industrial users, this supports long-term power continuity and equipment protection.
2. Disaster Suppression Design
The product page mentions proprietary pressure relief and absorption devices. This feature helps improve operational safety under fault conditions and supports safer electrical room design.
3. Compact and Flexible Structure
The space-saving design allows the customer to optimize the medium-voltage electrical room layout. This is especially useful for industrial plants, commercial buildings, and infrastructure projects where installation space is limited.
4. Efficient and Environmentally Friendly Air-insulated Design
The rational main busbar distribution and air insulation design help improve system efficiency while supporting a cleaner and more practical medium-voltage power distribution solution.
5. Standardized Operation and Interlocking
The interlocking design improves operation safety and helps prevent incorrect switching procedures during daily operation and maintenance.
GAOBO’s technical team first reviewed the customer’s electrical system requirements, including incoming voltage, transformer capacity, feeder quantity, load type, short-circuit current level, protection requirements, installation site conditions, and future expansion plans.
At this stage, the team confirmed the number of cabinets, switchgear function units, rated current, protection relay configuration, cable entry method, busbar arrangement, and overall layout.
After requirement analysis, GAOBO prepared a customized technical solution. The design included cabinet arrangement, single-line diagram, primary circuit scheme, secondary control scheme, protection and metering configuration, and cabinet layout.
The customer reviewed and confirmed the drawings before production. This helped ensure that the final switchgear lineup matched the project’s power distribution structure and site installation conditions.
According to the customer’s load requirements, GAOBO selected suitable medium-voltage components, protection devices, busbar systems, grounding switches, control instruments, and monitoring units.
The cabinet functions were divided clearly into incoming, outgoing, metering, bus section, and transformer protection units. This modular configuration improved operation management and maintenance convenience.
After the technical drawings were confirmed, GAOBO started factory manufacturing and assembly. The process included cabinet structure production, busbar installation, component mounting, secondary wiring, grounding system assembly, mechanical interlocking installation, and internal quality inspection.
Because the product is manufactured in a controlled factory environment, the overall product consistency and assembly quality can be better managed.
Before delivery, the switchgear cabinets were inspected according to project requirements. The inspection covered cabinet appearance, mechanical operation, busbar connection, grounding continuity, wiring accuracy, insulation performance, protection circuit function, interlocking mechanism, and basic operation tests.
This step helped reduce risks during on-site installation and commissioning.
After passing factory inspection, the switchgear was packed and delivered to the project site. The customer completed cabinet positioning, foundation fixing, cable connection, grounding connection, and site commissioning according to the approved installation plan.
GAOBO provided technical support for installation guidance, commissioning coordination, and operation preparation.
During commissioning, the team checked the primary and secondary circuits, protection relay settings, electrical interlocking, mechanical operation, metering function, and communication signals. After all items were confirmed, the medium-voltage switchgear system was put into operation.
The customized Siemens NXAirs LP Medium Voltage Switchgear Cabinet solution helped the customer build a safer, more compact, and more reliable medium-voltage power distribution system.
Key benefits included:
This project plan case demonstrates how GAOBO’s Siemens NXAirs LP Medium Voltage Switchgear Cabinet can support modern medium-voltage power distribution projects with safety, reliability, flexibility, and compact installation advantages.
For customers building industrial plants, commercial facilities, infrastructure projects, renewable energy stations, or utility distribution systems, a reliable medium-voltage switchgear solution is essential for stable power supply and long-term operational safety.
With Siemens NXAirs LP production authorization, professional design experience, and customized manufacturing capability, GAOBO SWITCHGEAR MANUFACTURER can provide medium-voltage switchgear solutions according to different project voltage levels, rated current requirements, protection schemes, installation environments, and customer standards.
If you are looking for a customized NXAirs LP medium-voltage switchgear cabinet or a complete medium-voltage power distribution solution, GAOBO can support your next project with professional engineering design, manufacturing, testing, and technical service.
