Modular Design GGJ Drawer Type Low Voltage Switchgear System

Product Name: GGJ Drawer-type Switchgear

Product Description: The GGJ Drawer Switchgear is a state-of-the-art low-voltage switchgear designed for high efficiency and reliability in power distribution. It is widely used in power plants, substations, industrial and mining enterprises, and high-rise buildings for power distribution centers (PC) and motor control centers (MCC). This switchgear is suitable for three-phase four-wire and three-phase five-wire power systems with a frequency of 50/60Hz, rated voltage of 380V, and rated current up to 4000A.

Key Features:

1. Modular Design:

   • The GGJ draw-out switchgear boasts a combined assembly structure, allowing for flexible assembly and modular installation. This design enables easy customization and adaptation to various configurations and scheme changes.

2. Safety and Separation:

   • The switchgear compartment is divided into function unit chamber, bus chamber, and cable chamber, ensuring the independence and strict isolation of each unit. This separation prevents accidents and facilitates maintenance.

3. Drawer Type Units:

   • The GGJ features draw-out units for feeders, motors, and common power supplies. Each unit is designed with a modular height of 200mm and is rated for currents less than 630A. The MCC cabinet can accommodate up to 9 Unit 1 drawers or 18 smaller units.

4. Mechanical Interlocking:

   • The operating mechanism of the main switch can lock the switch in either the OFF or ON position, ensuring safe maintenance of electrical equipment.

5. Corrosion Resistance:

   • The switchgear's internal structure is galvanized, and the external surface is treated with phosphate before being coated with electrostatic epoxy powder, providing resistance to wear and corrosion.

6. Isolation and Earthing:

   • The function unit compartment uses metal partitions for separation, and the earthing plug ensures circuit continuity during separation testing.

The GGJ Drawer Type Switchgear is an optimal choice for applications where flexibility, safety, and modularity are paramount. Its advanced design and high-standard construction make it a preferred solution in various electrical distribution and control scenarios.
