Nauru Explosion-proof Distribution Box Specifications and Models

The Nauru explosion-proof distribution box is designed for hazardous and harsh environments, featuring high structural strength, corrosion resistance, and compliance with industrial safety standards.General Design and StructureThe Nauru YBF series box-type substation is a prefabricated, fully assembled unit suitable for wind power and other industrial applications. It consists of multiple compartments: a high-voltage switchgear room (40.5kV), a low-voltage switchgear room (0.69kV), and a booster transformer room (0.69/35kV). The box body is typically made of high-quality steel plates with surface anti-corrosion treatment, or optionally anodized aluminum alloy plates or color steel composite panels. Insulation materials are added internally to ensure proper temperature regulation and safe operation of electrical components .Electrical SpecificationsHigh-voltage side: Uses XGN-40.5 box-type fixed high-voltage switch cabinet with a load switch-fuse combination device for transformer protection. Incoming and outgoing lines employ terminal-type load switches with integrated protective fuses and silicone rubber composite bushings .Low-voltage side: Cabinet structure with direct outgoing lines; lighting boxes provide control and auxiliary power. Voltage levels include 380V and 220V, with rated currents and short-time withstand currents customizable (e.g., 250A/10kA) .Circuit protection: Main switches and protection levels can be configured, e.g., single-phase or three-phase main switches with IP30 or higher protection .Environmental and Operational ParametersAmbient temperature: -30°C minimum, up to 45°C maximum; 24-hour average ≤35°C .Humidity: Daily average relative humidity ≤95%, monthly average water vapor pressure ≤1.8–2.2 kPa .Altitude: ≤1000 meters.Seismic resistance: Horizontal acceleration
