Low voltage fixed distribution cabinet
summary
GGD type low-voltage fixed switchgear can be widely used in AC 50Hz rated low-voltage 400V rated current to 6300A distribution systems for power plants, substations, factories, mining enterprises and other power users. It is used for power conversion, distribution and control of power, lighting and distribution equipment.
The GGD type low-voltage distribution cabinet has the characteristics of high breaking capacity, good dynamic and thermal stability, novel and reasonable structure, practical electrical scheme, strong series and applicability, and high protection level. It can be used as a replacement product.
This product complies with standards such as IEC60439 "Low Voltage Switchgear and Control Equipment" and GB7251.1 "Low Voltage Switchgear and Control Equipment Part 1: Type Testing and Partial Type Testing Equipment".

Productibus Features
The GD cabinet breaks through the structural form of old products, with a basic frame of a combination assembly structure. All structural components of the frame are firmly connected with screws, and the long legs, doors and panels are all phosphated and sprayed with polyester fine grain coating. Non sprayed parts are galvanized and passivate. Level protection is incllosurae IP30 est, et etiam inter IP2 et IP40 elegere potest secundum requies loci installationis utentis. Hoc cabinet in bona natural ventilatione system a conditus est.
There are commonly used upper and lower inlet methods for GGD, and inlet methods are also designed from the top, left, center, and right positions of the cabinet to meet the needs of various engineering designs for different inlet methods. At the same time, there are fixed positions inside the cabinet for special users such as power plants to install relay protection and automatic installation
The GGD cabinet has the characteristics of high breaking capacity, good dynamic and thermal stability, and flexible and convenient electrical scheme combination.
