Real-world Application Case

Case 1: 11kV Distribution Project at a 110kV Substation in Southeast Asia

1. Project Background: This substation is a core power supply hub in the region, requiring a stable 11kV power supply to surrounding industrial parks and residential areas. The equipment must possess high reliability and compliance, and be compatible with the local 50Hz power system.

2. Application Solution: Usune customized 28 KYN28A-12 11kV MV VCB Panels, adopting a single busbar segmented architecture and equipped with VS1 vacuum circuit breakers to meet dual-circuit power supply requirements.

3. Implementation Results: In the three years since its commissioning, the equipment has operated without any failures, successfully passing multiple tests under extreme conditions such as thunderstorms and high temperatures. It accurately completes power distribution and fault protection, helping the substation achieve "zero power outage operation and maintenance," and has received high recognition from the local power department.

Case 2: High-Voltage Power Distribution Upgrade at a European Automobile Manufacturing Plant

1. Project Background: The stamping and painting workshops of the factory have extremely high requirements for power supply stability, necessitating an upgrade to an 11kV power distribution system. The equipment must comply with EU IEC standards, while also considering ease of maintenance and space utilization.

2. Application Solution: 16 Usune 11kV MV VCB Panels were selected, employing a centrally located handcart structure, compatible with a single busbar system, and equipped with anti-condensation heaters and intelligent temperature and humidity monitoring modules.

3. Implementation Results: The equipment perfectly adapts to the European 50Hz/60Hz dual-frequency system. Installation does not affect normal workshop production, and the handcart can be quickly pulled out for maintenance. After the upgrade, the factory's power supply failure rate decreased by 90%, meeting the continuous production needs of automobile manufacturing.

Working Environment

1.Ambient air temperature: maximum +40°C, minimum -10°C;
2.Relative humidity: daily average ≤ 95%, monthly average ≤ 90%;
3.Altitude: ≤ 1000 m;
4.Seismic intensity: not exceeding Grade 8;
5.The equipment shall be installed in locations free from fire or explosion hazards, severe pollution, chemical corrosion, and strong vibration.
6.If the equipment is to be used under environmental conditions exceeding the normal requirements specified in GB 3906, relevant arrangements shall be agreed upon by the user and the manufacturer.
