China Suppliers Factory Low Noise Eco-Friendly 10kV Prefabricated Substation for Residential Areas
Multiple Safety Guarantees and Convenient Maintenance Features
๐
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.
๐ก
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".
๐ง
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 (FAQ)
Q
What rated capacity range does this box-type transformer support?
The transformer supports a rated capacity range of 100 KVA to 1250 KVA, making it suitable for a wide variety of power supply scenarios including industrial, commercial, and temporary construction sites.
Q
What protection grade does the box-type transformer enclosure provide?
All three compartments โ the high-voltage electrical cabinet, transformer, and low-voltage electrical cabinet โ are rated at IP23, providing protection against solid objects larger than 12.5mm and against water spray at an angle up to 60ยฐ from vertical.
Q
How does the intelligent monitoring system work and what parameters does it track?
The optional intelligent monitoring system wirelessly transmits real-time data to a remote monitoring center. It tracks transformer temperature, load rate, key node temperatures, door access status, and ambient temperature and humidity โ enabling condition-based maintenance and proactive fault early warning.
Q
Is this box-type transformer suitable for temporary or rental power supply projects?
Yes. The unit is equipped with standard lifting holes and transportation fixation points at the base, allowing it to be relocated using standard lifting equipment. Relocation only requires disconnecting the incoming and outgoing cable connections, making it highly practical for rental markets and temporary power supply applications.
Q
What safety interlocking mechanisms are included to prevent accidental access?
The high-voltage and low-voltage rooms are each fitted with either mechanical or electrical interlocks, which strictly prevent personnel from accidentally entering energized compartments. The door locks also feature anti-picking design to deter unauthorized access.
Q
What is the maximum number of outgoing loops available on the low-voltage side?
The low-voltage electrical cabinet supports between 4 and 30 outgoing loops, offering flexible configuration to meet different distribution network requirements. Additionally, the maximum reactive power compensation capacity on the low-voltage side is 300 kvar.
