Main Circuit Scheme
The GGD series offers an extensive range of 129 main circuit schemes and 298 specifications, ensuring comprehensive solutions for varied industrial requirements. GGD1 features 49 schemes and 123 specifications, GGD2 provides 53 schemes with 107 specifications, and GGD3 offers 27 schemes and 68 specifications, effectively meeting the diverse needs of power plants and other sectors. Tailored to accommodate rated currents up to 3150A, it supports distribution transformers up to 2000kVA. Additionally, to address reactive power compensation, the line includes GGJ1 and GGJ2 transmission compensation cabinets with 4 schemes and 12 specifications in total. AC Low Voltage Distribution CabinetThe main circuit designs have been curated with input from design and usage departments, ensuring they meet the specific requirements of power plants. With solutions for reactive power compensation, our GGJ1 and GGJ2 transmission compensation cabinets offer 4 main circuit schemes and 12 specifications. This adaptability confirms the cabinet's suitability for distribution transformers up to 2000kVA, with a rated current capacity reaching 3150A.
Auxiliary Circuit Scheme
The auxiliary circuit design is meticulously structured into power supply and power plant schemes. The BGD cabinet is spacious enough to accommodate secondary components, ensuring seamless integration. NLS has innovated with the LM23D current transformer, catering to power plants and specialized users, particularly when relay protection is a necessity.
Main Bus-Bar
Our bus-bar design prioritizes cost-effectiveness and operational efficiency. For rated currents below 1500A, a single aluminum bus is utilized, while currents exceeding 1500A employ a double copper bus. Recognizing user preferences, the manufacturer can interchange aluminum with copper buses of equivalent capacity. All bus surfaces are meticulously treated with the pond tin process, ensuring durability and corrosion resistance.
Selection of Electrical Components
The GGD Type AC Low-Voltage Distribution Cabinet features top-tier, domestically mass-produced electrical components, harmonizing advanced technology with economic viability. By retaining reliable older models like DZ10D and D220, the cabinet ensures a balance of innovation and proven performance, steering clear of obsolete technologies.
NLS has specifically designed the HD13BX and HS13BX rotary operated knife switches for the unique architecture of the BGGD cabinet. These components revolutionize operational mechanisms while preserving the strengths of existing models, offering practicality and enhanced functionality.
For those seeking cutting-edge advancements, the GGD Type AC Low-Voltage Distribution Cabinet offers exceptional installation flexibility, accommodating new electrical components with superior performance and technology. This adaptability ensures that updates and modifications in components pose no challenge to manufacturing or installation processes.
To elevate the dynamic stability of the main circuit to unparalleled heights, NLS has ingeniously crafted the ZM combined bus clamp and insulation support tailored for the GGD cabinet. This innovative bus bar clamp is constructed from high-strength, high-flame-retardant Pp0 alloy material, offering superb insulation strength and exceptional self-extinguishing capabilities, all wrapped in a unique design. The brilliance of its construction allows for effortless assembly into either a single or double bus bar clamp, simply by tweaking the building block configuration. Complementing this design, the insulation support features a sleeve-type molded joint, delivering low cost without compromising on strength. This solution effectively addresses the previous limitation of inadequate creepage distance, setting a new standard for safety and performance.
Installation and Use
Upon arrival at your location, it is crucial to first verify the intactness of the packaging. Should any issues arise, promptly inform the relevant departments to swiftly identify and rectify the causes. For products not slated for immediate installation, ensure they are stored in suitable locations that adhere to the recommended normal use conditions, safeguarding their integrity and functionality.
Product Installation
To ensure flawless installation, adhere closely to the installation schematic diagram provided (refer to the attached figure). Users are responsible for supplying the basic channel steel and bolts. When installing the main bus in a continuous row with tin plating, meticulous attention should be paid to repairing, leveling, and cleaning the overlapping surface. Apply neutral vaseline or adopt other protective measures before securing it firmly with bolts, guaranteeing a seamless and robust installation.
