Compact Substation Manufacturer - Packaged & Prefabricated
Factory-assembled package substations that combine high-voltage switchgear, a distribution transformer and low-voltage distribution in a single transportable enclosure, for rapid deployment at industrial parks, commercial sites and infrastructure projects.

- Complete substation in one enclosure — HV switchgear, transformer and LV distribution factory-assembled as one unit.
- Two layouts — European three-compartment style or American pad-mounted style.
- Oil-immersed transformer — S11 low-loss transformer, Dyn11, ONAN cooling.
- Steel enclosure — sheet-steel housing with powder coating; colour to order.
- Project configuration — HV switch type, transformer capacity and LV outgoing ways configured to your single-line diagram.
Model Meaning
XT-YB-<capacity>-<type>: capacity is the transformer rating in kVA; E is the European style with separate HV, transformer and LV compartments; A is the American pad-mounted style with an integrated layout. Example: XT-YB-630-E is a 630 kVA European-style package substation. Other capacities and voltage classes are built to order.
Service Conditions
For outdoor floor-standing installation on a prepared concrete foundation. Standard rating: HV 10 kV class, LV 0.4 kV, connection group Dyn11. Protection class designed per IEC 60529 (tested on request).
