Transformer Sourcing, Substation & Switchgear Integration Services
From specification engineering to on-site commissioning — we provide end-to-end technical support for substation transformers, switchgear integration, MV/LV distribution, step-up / step-down units, dry-type and oil-immersed designs for EPC contractors, utility grid operators, mining, renewable-energy and industrial buyers.
Independent Test Verification
High-Voltage Impulse Test Hall
Type tests such as lightning impulse (BIL) and switching impulse withstand are witnessed in dedicated high-bay test halls like this one — verifying insulation coordination before a unit ever ships. We arrange witnessed testing for every project that requires it, with full documentation included in your FAT package.
Custom Transformer Design & Engineering
Tailored specifications for your exact application
Every transformer project starts with unique requirements — voltage class, MVA rating, cooling type, vector group, impedance, and environmental conditions. Our engineering team translates your project needs into precise manufacturer specifications, ensuring the transformer is designed for your actual operating environment.
What's Included
- Voltage class selection (10kV to 220kV)
- Capacity sizing and load analysis
- Cooling system design (ONAN, ONAF, OFAF, ODAF)
- Vector group and impedance specification
- Environmental adaptation (desert, tropical, arctic, altitude)
Factory Audit & Qualification
Verified manufacturers with proven track records
Not all transformer factories are equal. We maintain a qualified supplier network through rigorous on-site audits — verifying design capability, manufacturing equipment, test laboratories, and quality systems against IEC and IEEE standards.
What's Included
- On-site factory capability assessment
- IEC/IEEE test laboratory verification
- ISO 9001 and ISO 14001 system audit
- Production capacity and lead time validation
- Export track record and reference verification
Full-Process Quality Control
Witnessed testing per IEC 60076 standards
Transformer quality is verified through testing — not just visual inspection. We witness all critical tests at the factory, from routine tests on every unit to type tests and special tests, ensuring your transformers meet international standards before shipment.
What's Included
- Routine tests: ratio, winding resistance, insulation, losses
- Type tests: temperature rise, lightning impulse, short-circuit
- Special tests: DGA baseline, FRA, noise measurement
- Third-party witness testing coordination (KEMA, BV, SGS)
- FAT reports with complete test documentation
International Logistics & Compliance
Heavy cargo expertise from factory to substation
Transformers are oversized, heavy, and oil-filled — they require specialized project cargo handling. We manage the entire logistics chain including route surveys, heavy-lift vessels, customs clearance, and on-site delivery coordination with crane and rigging crews.
What's Included
- Project cargo planning and route surveys
- Breakbulk and heavy-lift vessel booking
- CE, IEC, and local grid code compliance documentation
- Customs pre-clearance and import permits
- On-site delivery coordination and commissioning support
