Frequently Asked Questions
Q What are the three compartments in this compact substation?
The unit is divided into three functional rooms: the high-voltage room, the transformer room, and the low-voltage room. This layout ensures a highly integrated system, safe isolation between components, and ease of maintenance.
Q How much space does this substation save compared to conventional substations?
This compact substation occupies only 1/10 to 1/5 of the space required by a conventional substation of equivalent capacity. This significantly reduces land usage, civil engineering workload, and overall construction costs.
Q What is the IP protection rating and what does it mean for outdoor use?
The enclosure carries an IP34D protection rating, which means it is protected against solid particles larger than 1mm and splash water from any direction. This makes it well-suited for outdoor installation in environments exposed to dust and moisture.
Q What transformer types and capacity ranges are supported?
The product supports both oil-immersed and dry transformers. The transformer capacity commonly ranges from 100 kVA to 1,250 kVA and above, making it adaptable to a wide range of power distribution needs from small commercial sites to large industrial facilities.
Q What power supply modes does this substation support?
It supports three power supply configurations: ring network power supply for looped grid systems, dual power supply for redundancy and reliability, and radial terminal power supply for straightforward end-point distribution. This flexibility allows it to integrate into various grid architectures.
Q Where is this compact substation typically installed?
It is widely deployed in urban residential areas, commercial centers, industrial parks, public facilities, and temporary construction sites. Its compact size allows it to be positioned close to the load center, minimizing transmission distances and reducing line losses effectively.
