Compact 10kV Prefabricated Substation from China Suppliers - Modern Factory Solution for Urban Power Distribution
Flexible Grid Connection and System Compatibility Capabilities
1. Complete Ring Network Solution
Configurable fully insulated and fully sealed ring network cabinet units, enabling advanced power supply modes such as dual-ring network and single-ring network. Each unit is connected through prefabricated cables, forming a complete ring network system. In the event of a fault in any section of the line, it can be quickly isolated and power restored, with power reliability reaching 99.99%.
2. Dual Power Automatic Switching System
It can provide a complete dual power access solution for important users, equipped with an automatic transfer switch (ATS) and corresponding protection systems. When the main power supply fails, the backup power can be automatically switched on within an extremely short period of time, ensuring uninterrupted power supply for critical loads such as hospitals, data centers, and important production lines.
3. Standardized Radial Terminal Configuration
To meet the radial power supply requirements of ordinary users, an economical and efficient standardized configuration solution is provided. On the high-voltage side, a load switch-fuse combination electrical apparatus can be used to protect the transformer. On the low-voltage side, intelligent frame circuit breakers and molded case circuit breakers are configured to form a complete protection system.
4. Future-Oriented System Scalability
Adopting a modular design concept, standard interfaces are reserved for electrical wiring. When the user's load increases in the future, it can be expanded quickly by replacing the transformer module or increasing the capacity of the low-voltage cabinet module. This design reduces the expansion cost during the product's life cycle by more than 50%.
