Product Q&A
Q:What is a prefabricated substation?
A:
A factory-built, factory-tested power distribution unit that integrates HV switchgear, transformer, and LV panels inside a single weatherproof enclosure. It arrives on site as one piece - lift onto a foundation, terminate cables, energize.
Q:Why choose this over a traditional substation?
A:
1. 50% shorter construction time and ~10% lower cost;
2. 1/3 to 1/5 the footprint of a conventional build;
3. Single-source responsibility - one supplier for design, manufacture, testing, and commissioning;
4. Relocatable - disconnect, lift, and move to a new site.
Q:What voltages and capacities?
A:
1. HV side: 6kV to 110kV (most common: 10kV, 20kV, 35kV)
2. LV side: 400V standard
3. Capacity: 30kVA to 2,500kVA
Q:Oil-immersed or dry-type transformer?
A:
Oil-immersed: Lower cost with superior overload capacity. Standard choice for outdoor industrial applications.
Dry-type: Fire-safe and low maintenance. Preferred for indoor/underground installations, hospitals and urban residential areas.
Both can be housed within the same enclosure. Dry-type insulation options: Class F (155 deg C) or Class H (180 deg C).
Q:How long does installation take?
A:
3-7 working days on site** (foundation prep, crane placement, cable termination, commissioning). A conventional substation takes 4-12 weeks.
