Low Noise Eco-Friendly 10kV Compact Prefabricated Substation from China Suppliers and Factory for Residential Areas
Multiple safety guarantees and convenient maintenance features
1. Multi-layer physical protection system
The box body adopts anti-theft design, and the door lock has anti-picking function. Mechanical interlock or electrical interlock is set in the high-voltage room and the low-voltage room respectively, strictly preventing accidental entry into the energized compartments. The transformer room is equipped with an independent pressure relief channel, which can quickly release pressure in case of a fault, ensuring the safety of personnel and equipment.
2. Intelligent Monitoring and Early Warning
An optional intelligent monitoring system can be equipped. It can monitor parameters such as transformer temperature, load rate, key node temperature, access status, and environmental temperature and humidity in real time. The data is transmitted wirelessly to the monitoring center, enabling remote operation and fault early warning, transforming "scheduled maintenance" into "condition-based maintenance".
3. Humanized maintenance design
Each functional room is equipped with an independent maintenance door, and the width of the maintenance passage complies with safety standards. The high-voltage cable heads are designed with a touchable feature, allowing for safe operation without the need for special tools during maintenance. The main components are all designed with front maintenance features, enabling all maintenance operations to be completed from the front.
4. Quick relocation and reuse
The bottom of the box is equipped with standard lifting holes and transportation fixation points, allowing for overall handling using general lifting equipment. During relocation, only the incoming and outgoing cable connections need to be disconnected, significantly enhancing the equipment's utilization rate and return on investment. It is particularly suitable for the rental market and temporary power supply scenarios.

Frequently Asked Questions
What safety features are included in the physical protection system?
The system features an anti-theft box design, anti-picking door locks, mechanical or electrical interlocks in both the high-voltage and low-voltage rooms to prevent accidental entry, and an independent pressure relief channel in the transformer room for quick pressure release during faults.
How does the intelligent monitoring system work?
The optional system tracks real-time parameters such as transformer temperature, load rate, key node temperature, access status, and environmental conditions. This data is sent wirelessly to a monitoring center for remote operations and early warnings, enabling condition-based maintenance.
Is the maintenance process tool-free?
Yes, the high-voltage cable heads are designed to be touchable, allowing safe maintenance operations without requiring specialized tools. Additionally, all main components are accessible from the front maintenance doors.
Can the box-type transformer be easily relocated?
Yes, it is designed for quick relocation with standard lifting holes and transportation fixation points at the bottom. During relocation, only the incoming and outgoing cable connections need to be disconnected, making it ideal for temporary power supply or rental markets.
What is the shell protection grade and noise level?
The shell protection grade is IP23. The noise level is less than 55 dB for oil-type transformers and less than or equal to 65 dB for dry-type transformers.
What are the nominal voltage ratings for the cabinets?
The nominal voltage is 10 KV for the high-voltage electrical cabinet, 10/0.4 KV for the transformer, and 0.4 KV for the low-voltage electrical cabinet.
