Certified Quality Management System covering design, coil winding, vacuum drying, oil filling, and routine testing of 10kV–35kV distribution transformers.
Environmental Management System certifying low-loss eco-designed core assemblies, zero PCB insulation oil, and environmentally safe production controls.
Occupational Health and Safety Management System ensuring safety containment in high-voltage testing bays and factory assembly protocols.
Complete routine and type test records (temperature rise, impulse voltage withstand, short-circuit withstand) conducted at CNAS-accredited national research institutes.
On-site factory audit certificate by SGS / Made-in-China, verifying manufacturing premises, export capacity, assembly lines, and legal qualification.
Verified annual supply performance and delivery certificate for overseas power grid EPC and industrial infrastructure projects (Mozambique, Nigeria, Kenya, SEA).
Technical Overview
Prefabricated compact substations (also known as packaged substations, kiosk substations, or pad-mount substations) integrate high-voltage incoming switchgear (RMU), a power transformer, and low-voltage outgoing switchboards inside a single weather-proof, tamper-resistant enclosure.
XinHuan's manufacturing plant produces both European Kiosk Substations (independent MV room, transformer room, and LV room layout with walk-in or non-walk-in designs) and American Pad-Mounted Substations (compact co-tank design with dead-front elbow connectors, ideal for underground residential and commercial distribution).
Every substation is completely assembled, pre-wired, and routine-tested at our Hefei factory before containerization, reducing site installation and commissioning time from weeks to just a few hours.
