Main Circuit Scheme
The GGD distribution cabinet offers an impressive array of 129 main circuit schemes and 298 specifications, ensuring comprehensive adaptability. Among these, GGD1 provides 49 schemes with 123 specifications, GGD2 offers 53 schemes and 107 specifications, while the GGD3 model boasts 27 schemes with 68 specifications. These configurations are meticulously curated based on feedback from design and user departments, enriching the system for power plant needs. Meeting distribution transformer requirements up to 3150A, these schemes are ideal for transformers of 2000kVA and below. Moreover, GGJ1 and GGJ2 transmission compensation cabinets cater to reactive power compensation, featuring 4 main circuit schemes with a total of 12 specifications. AC Low Voltage Distribution CabinetThese configurations exclude those derived from auxiliary circuit functional changes and control voltage variations. With its wide-ranging suitability, the GGD series addresses diverse power distribution challenges. Additionally, GGJ1 and GGJ2 cabinets enhance reactive power compensation with their specialized designs.
Auxiliary Circuit Scheme
The auxiliary circuit design is thoughtfully divided into the power supply and power plant schemes. The BGD cabinet offers ample space for secondary component installation. Furthermore, NLS has devised the advanced LM23D current transformer to meet specialized needs for relay protection in power plants and unique user requirements.
Main Bus-bar
Emphasizing cost-effectiveness and flexibility, the bus-bar selection includes a single aluminum bus for currents below 1500A and a double copper bus for those above 1500A. Prototypes are crafted following these guidelines and undergo stringent type testing. The manufacturer also accommodates user preferences for copper bus replacements without compromising current capacity. All bus overlapping surfaces are expertly treated with the pond tin process for superior durability.
Selection of Electrical Components
The GGD Type AC low-voltage distribution cabinet predominantly utilizes cutting-edge electrical components manufactured en masse in China. Balancing modernity with practicality, it retains reliable veteran products such as DZ10D and D220 when feasible, ensuring economic and rational operation, while consciously avoiding obsolete elements.
Specially designed for the distinctive structure of the BGGD cabinet, the HD13BX and HS13BX rotary operated knife switches by NLS transform operational methodologies while preserving the benefits of traditional components, offering practicality and efficiency in one package.
The GGD Type AC low-voltage distribution cabinet adapts seamlessly to the integration of new, high-performance electrical components with advanced technology, as recommended by design departments and user needs. Its flexible installation framework ensures that updates in electrical components pose no manufacturing or installation challenges.
To elevate the dynamic stability of the main circuit, NLS has ingeniously crafted the ZM combined bus clamp and insulation support, specifically designed for the GGD cabinet. Our bus bar clamp, meticulously constructed from high-strength, high-flame-retardant PP0 alloy material, boasts superior insulation strength and exceptional self-extinguishing capabilities. Its uniquely crafted structure allows seamless transformation between a single bus bar clamp and a double bus bar clamp, simply by tweaking the building block configuration. Additionally, our sleeve-type molded joint insulation support offers a cost-effective, high-strength solution, effectively addressing the inadequate creepage distance found in traditional products.
Installation and Use Guidelines
Upon the product's arrival at your site, immediately inspect the packaging for any signs of damage. Promptly communicate with the relevant departments to identify and address any issues discovered. For items not intended for immediate installation, ensure they are stored in optimal locations, adhering to the standard conditions for normal use.
Product Installation Overview
Product installation must strictly follow the provided schematic diagram (refer to the attached figure). Users are responsible for supplying the basic channel steel and bolts. During the installation of the main bus in a continuous row with tin plating, ensure that the overlapping surfaces are carefully repaired, leveled, and cleaned. Apply neutral vaseline or similar protective measures before securing everything firmly with bolts.
