China Suppliers Factory Offering Low Noise Eco-Friendly 10kV Prefabricated Substation for Residential Areas
Multiple Safety Guarantees and Convenient Maintenance Features
-
๐1. 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.
-
๐ก2. 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".
-
๐ง3. 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.
-
๐4. 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 safety protection measures does the box-type transformer provide against unauthorized access?
The box body is designed with an anti-theft structure, and the door lock features an anti-picking function. Both the high-voltage room and the low-voltage room are equipped with mechanical or electrical interlocks to strictly prevent accidental entry into energized compartments, ensuring personnel safety at all times.
Q
Does the box-type transformer support remote monitoring and fault warning?
Yes. An optional intelligent monitoring system can be integrated to monitor transformer temperature, load rate, key node temperature, access status, and environmental temperature and humidity in real time. Data is transmitted wirelessly to a monitoring center, enabling remote operation and proactive fault early warning.
Q
What is the rated capacity range of the transformer in this unit?
The transformer supports a rated capacity range of 100 KVA to 1250 KVA, making it suitable for a wide variety of commercial, industrial, and temporary power supply applications.
Q
How easy is it to relocate the box-type transformer to a new site?
Relocation is straightforward. The unit's base is fitted with standard lifting holes and transportation fixation points, allowing it to be moved with general lifting equipment. Only the incoming and outgoing cable connections need to be disconnected, minimizing downtime and making it ideal for rental markets and temporary power supply projects.
Q
What is the shell protection grade of this box-type transformer?
All three compartments โ the high-voltage electrical cabinet, transformer, and low-voltage electrical cabinet โ carry an IP23 protection rating, providing reliable protection against solid objects and water ingress in standard outdoor and semi-outdoor installation environments.
Q
Can maintenance be performed without specialized tools or shutting down the entire unit?
Yes. Each functional room has an independent maintenance door with passage widths compliant with safety standards. The high-voltage cable heads feature a touchable design for safe operation. All major components are designed for front-access maintenance, so all routine maintenance tasks can be completed from the front without specialized tools.
