- Product Description
-
Scope of Application
The GGD-type low-voltage fixed switchgear is designed for use in power distribution systems—such as those found in power plants, substations, industrial facilities, and other electricity-consuming enterprises—as part of AC 50Hz systems with a rated operating voltage of 380V and a rated current capacity up to 6300A. It serves primarily for the conversion, distribution, and control of electrical energy in applications involving power supply, lighting, and general-purpose equipment. This product boasts high breaking capacity, with a rated short-time withstand current reaching up to 50 kA, along with features like flexible circuit configurations, convenient modular combinations, exceptional practicality, and an innovative design. As such, it stands out as one of China’s leading examples of assembled, fixed-panel switchgear cabinets.
This product complies with standards such as GB7251.12-2013 "Low-Voltage Switchgear and Controlgear Assemblies" and IEC60349 "Low-Voltage Switchgear and Controlgear Assemblies."
Normal operating conditions
● Ambient temperature: -50°C to +40°C, with the average temperature not exceeding +36°C over any 24-hour period.
●Altitude: Not exceeding 2500m.
●Relative humidity: Not exceeding 50% when the ambient air temperature is +40°C. At lower temperatures, higher relative humidity levels are permissible (e.g., up to 90% at +20°C), allowing for moderate condensation under varying temperature conditions.
● The tilt of the equipment relative to a vertical surface should not exceed 5° during installation.
● The equipment should be installed in a location free from severe vibrations, impacts, and corrosive environments.
Note: If the above conditions cannot be met and the user has special requirements, please contact our company to discuss a possible solution.
