Worldwide, air-insulated technology has served as a basis for an established, reliable power supply for more than 100 years. The NXAIR family has been continuously developed since 1998, and individually adapted to the specific market requirements of the different industries and power supply companies. NXAIR conforms to the defined standards of IEC, GOST and GB/ DL, partly exceeding them. The proven resistance to internal faults provides highest personal safety, and thus a sustainable increase of productivity. Due to the compact design and low maintenance requirements of NXAIR, saving potential can be generated in any industry. This is our promise to our customers. 3

4 For your requirements NXAIR offers the solution Due to its adaptable design, NXAIR offers high flexibility to satisfy individual customer requirements. Our specialists design customized solutions for you, even for adverse climatic conditions, at maximum or minimum ambient air temperatures, under high air humidity, as well as in case of heavy pollution of ambient air with dust, gases, salts or chemically active vapors. Many details of NXAIR can be modified, and manufactured according to the customer s requirements. Please find a small selection of options below: Cable connection Flexible in connection: Cables can be connected both from above and from below, and installation is possible from front or rear. Different cable types and cross-sections can be used. Current transformer connection Easily extendable: NXAIR offers space for up to 6 current transformers per panel (2 current transformers per phase). Different core classes and accuracies as well as individual protection concepts are possible. Upgrade of degree of protection The degree of protection of a switchgear must meet the most different requirements, depending on the area of application. With the corresponding additional measures, degrees of protection up to IP42 or IP51 can be reached, in order to operate NXAIR safely even under severe conditions. Components on the busbar For functions such as busbar earthing or busbar voltage metering, NXAIR does not require any additional panels, as these functions can be directly implemented by means of additional components mounted on the busbar. Cost savings and optimum utilization of switchgear buildings are guaranteed. Pressure relief The pressure relief of the switchgear can be designed individually, depending on the installation conditions inside the building or the customer s request. Whether into the building via absorbers or to the outside through a modular pressure relief duct system the pressure relief can be configured individually, and it is of course type-tested to ensure a high personal safety. Mimic diagram Depending on the customer s request, the mimic diagram with integrated mechanical position indicators can be supplied in different colors and with customer-specific symbols. 4

5 Safety at the highest standard. In every industry Automobile industry As a reliable partner of the automobile industry, NXAIR offers a cost-efficient product design with an especially developed automotive panel, for safe production at the factory. Due to the confinement of an internal arc to the respective compartment, NXAIR guarantees high availability and maximum opera- tional safety. NXAIR also fulfills the internal arc classification (IAC A FLR) according to the rated short-circuit current with internal arc duration of 1 s (IEC), and optionally with a rapid shutdown function of 0.1 s. Additionally, the special use of silicone-free or non-silicone-releasing components in NXAIR ensures a trouble-free painting process. Oil and gas industry To achieve maximum cost-efficiency, applications for the oil and gas industry must guarantee maximum reliability and availability around the clock. NXAIR reliably secures the power supply, even under adverse climatic and ambient conditions such as saline and humid climate or dust. Moreover, NXAIR ensures maximum personal safety due to its high standards. Steel industry As a delivering industry, the steel industry depends on the cycles of its customer sectors and is thus subject to economic fluctuations. A reliable and safe power supply is also re - quired for a high flexibility in production, in order to manufacture increasingly small-volume orders especially for mechanical engineering. NXAIR fulfills these requirements with its maintenance-free circuit- breakers and the maintenance-free withdrawable design, as well as with a high short-time withstand current. Power supply companies Power supply companies face growing energy demands due to increasing po pu lation numbers. Power consumption de pendent on time and availability, security of power supply, and grid stability are currently highly debated topics. NXAIR guarantees a reliable and costefficient power supply with low space requirements. Thanks to its modular design and intuitive operating logic, NXAIR provides for maximum personal safety during operation, as well as for high flexibility and availability. Data centers Data centers place high demands on permanent, uninterrupted power. Their servers are operating 24 hours a day, seven days a week, under strictly controlled ambient conditions. NXAIR smoothly integrates into the power distribution of data centers, and even fulfills future requirements with its advanced technology. The high quality of the switchgear provides for maintenance intervals of more than 10 years, thus saving significant life cycle costs. Both power supply with NXAIR and server monitoring are controlled from remote. Chemical industry With ever shorter cycles for development and market entry, product quality needs to be at the highest level. As an experienced partner of the chemical industry, NXAIR ensures smooth operation and exemplary availability. Even under the challenging ambient conditions of the chemical industry, NXAIR provides a reliable power supply with a long service life of more than 30 years. 5

6 NXAIR offers more Customer-oriented flexibility, high personal safety and low operation and maintenance costs high-performance NXAIR offers all the advantages of an all-round carefree package for power distribution. NXAIR ensures peace of mind NXAIR is developed and manufactured according to high quality and environmental standards. Maintenance-free design, maintenance-free type-tested vacuum circuit-breakers, and quality assurance throughout the process in accordance with DIN EN ISO 9001 and ensure smooth operation. NXAIR stands for optimum safety All switchgear types of the NXAIR family are approved with internal arc classification IAC A FLR, loss of service continuity category LSC2B, and partition class PM. For this purpose, the interlocks of the individual components are designed to fit in a way which prevents maloperation. Mechanical interlocking and unambiguous position indicators in the mimic diagram on the high-voltage door assist for operation without malfunctions. NXAIR increases productivity With its compact design, low maintenance requirements and uncomplicated, reliable technology, NXAIR ensures uninterrupted operation as well as a sustainable increase of productivity. NXAIR is an investment that pays off throughout its entire life cycle. NXAIR generates saving potential The low maintenance requirements with intervals of more than 10 years and the modular design of NXAIR enable a largely continuous operation without expensive downtimes. Due to the compact design and the flexible cable connection options or pressure relief duct systems, the space requirements are extremely low, which contributes to reduced building costs. NXAIR preserves the environment The insulating medium air is absolutely environmentally neutral and is always available. Special insulation gases do not need to be used. As a consequence, no gases will escape, and there is no moni toring necessary. Due to its service life of more than 30 years and a simple disposal at the end of the life cycle, NXAIR is a sustainable solution which optimizes your overall performance balance. 6
