I. Project Background

This project is a core component of Phase II of the Nanning Industrial Investment Automobile Yongning Industrial Park, covering Standard Factory Buildings 1#, 2#, and 3#, a comprehensive station building, a wastewater treatment station, an oil supply station, and plant roads, with a total construction area of 163,385 square meters. The primary focus of this project is to supply reliable high- and low-voltage power distribution core equipment for the BYD plant, ensuring the stability and safety of its production power supply.

As a large-scale modern production base, BYD's production lines impose extremely high demands on the continuity, stability, and safety of the power supply. Any power interruption or fluctuation could lead to significant production losses. The KYN28-12 high-voltage cabinets and SWGCS low-voltage cabinets deployed in this project are specifically designed and implemented to meet the stringent power requirements of such high-end industrial plants.

II. Customer Pain Points

Extremely High Power Supply Reliability Requirements:

The high automation level and dense equipment in the automobile manufacturing production line necessitate a highly continuous power supply, requiring the minimization of unplanned power outages.

Operational Safety as the Bottom Line:

The plant houses numerous personnel and equipment, requiring the power distribution system to incorporate comprehensive safety measures such as "five-prevention" interlocking to eliminate misoperation risks and ensure the safety of personnel and equipment.

Maintenance Convenience and Efficiency:

The large-scale power distribution system in the plant involves numerous devices, necessitating user-friendly and easy-to-maintain designs to reduce maintenance time and improve efficiency.

Equipment Adaptability and Lifespan:

The hot and humid climate of the Nanning region requires equipment with excellent moisture and corrosion resistance to ensure long-term stable operation and reduce lifecycle costs.

High Capacity and Scalability:

The system must meet current and potential future high-current power distribution demands arising from production expansion, requiring equipment with sufficient capacity and flexibility.

III. Proposed Solution

To address the high-standard power distribution needs of the BYD plant, we provided a suitable core power distribution equipment solution:

KYN28-12 (GZS1) High-Voltage Switchgear:

Ultimate Safety Protection:

Comprehensive mechanical and electrical interlocking strictly meets the "five-prevention" requirements. The high-voltage compartment is equipped with a pressure relief channel, and the front door features observation windows for status monitoring, establishing a solid safety foundation for plant operation.

High Reliability and Minimal Maintenance:

Utilizes high-performance ZN63A-12 (VS1) or imported IVD4 vacuum circuit breakers. The high reliability of core components effectively reduces failure rates and maintenance frequency.

Convenient Maintenance and Interchangeability:

The withdrawable truck design includes precise positioning and indication for working/test positions. Trucks of the same specification are freely interchangeable, and dedicated handling trolleys enable easy and flexible operation, significantly improving maintenance efficiency and reducing outage time.

Durability and Environmental Adaptability:

The cabinet body is made of imported aluminum-zinc coated steel plates, processed with multiple bending techniques and FMS systems, offering high structural strength, precision, lightweight, and excellent corrosion resistance, suitable for the hot and humid industrial environment of southern China.

Strong Connectivity:

The cable compartment can accommodate up to 9 single-core cables, meeting the dense wiring needs of large plants.

SWGCS Low-Voltage Withdrawable Switchgear:

High Capacity and High Applicability:

Rated current up to 6300A meets the power distribution demands of high-power equipment in the BYD plant. Widely used in modern factories requiring high automation levels and computer interfacing.

Flexible Withdrawable Design:

Functional units adopt a withdrawable structure, enabling quick isolation of faulty units during maintenance without affecting power supply to other circuits, ensuring production continuity.

Advanced Technology, Stable and Reliable:

Specifically designed and developed to meet domestic market demands, it features high technical performance indicators and stable operation, making it an optimal solution for power distribution systems in power plants and large industrial projects.

Reserved Interfaces for Smart Functionality:

Adapts to the trend of intelligent management in modern factories, meeting the needs for interfacing with building automation or energy management systems.

IV. Customer Value

Ensures Continuous and Stable Production:

The highly reliable high-voltage vacuum circuit breakers and robust cabinet structure, combined with the flexible withdrawable design of the low-voltage cabinets, minimize the risk of unplanned power outages, providing continuous power for BYD's production lines.

Strengthens Safety Defenses:

Comprehensive "five-prevention" interlocking, pressure relief channels, and other designs significantly reduce operational risks and potential accidents, ensuring the safety of plant personnel and assets.

Improves Operational Efficiency and Reduces Costs:

The convenient operation and interchangeability of high-voltage trucks and the quick plug-and-play of low-voltage units greatly simplify daily inspections and maintenance tasks, shorten fault resolution time, and reduce operational costs and losses due to downtime.

Durability and Optimized Lifecycle Costs:

High-quality materials (e.g., aluminum-zinc coated steel plates) and advanced manufacturing ensure long-term corrosion resistance and service life of the equipment in Nanning's hot and humid environment, reducing replacement frequency and total cost of ownership.

Meets Current and Future Needs:

The equipment provides sufficient capacity (particularly low-voltage high-current capability) and standardized design, offering a solid foundation for potential future production capacity increases or equipment expansion in the plant.

Complies with High-Standard Industrial Applications:

The KYN28 and SWGCS series products are mature and reliable solutions widely used in the domestic power and industrial sectors, with performance and quality meeting the stringent requirements for power distribution equipment in large automobile manufacturing plants.
