Quality Control

Uncompromising Quality Assurance, Stringent In-House Testing & International Compliance for Overseas Buyers

Stringent Quality Management & Global Compliance

At Urja Techniques (India) Pvt. Ltd., quality is the core foundation of our engineering philosophy. Designed to withstand demanding environmental conditions and heavy-duty industrial applications, every transformer we manufacture undergoes rigorous quality protocols from raw material procurement to final pre-shipment inspection.

Operating under an ISO 9001:2015, ISO 14001:2015, and ISO 45001 integrated management system since 1996, our Mumbai-based production facility adheres strictly to international electro-technical standards including IEC 60076, IS 2026, IS 1180, ANSI, and IEEE specifications.

Prime Raw Materials

100% electrolytic grade copper windings & prime laser-treated CRGO steel cores from certified global suppliers.

Controlled Winding

Dust-free enclosed clean-room winding stations preventing microscopic contamination and partial discharge risks.

Autoclave Processing

State-of-the-art Vacuum Pressure Impregnation (VPI) and automated drying cycles ensuring maximum dielectric strength.

CPRI & ERDA Tested

Comprehensive type-testing validation by independent government-accredited laboratories for global reliability.

Our commitment to technical perfection has enabled us to serve utility power grids, EPC contractors, renewable projects, and heavy industrial clients in over 40 countries across Africa, Europe, the Middle East, and Asia.

Key Quality Commitments

  • Zero Defect Manufacturing: 100% stage-wise quality checks during winding, core stacking, tanking, and oil filling.
  • Full Traceability: Complete batch test certificates (MTC) supplied for all core, conductor, and insulation materials.
  • In-House Temperature Rise Facility: Equipped with advanced precision load banks for mandatory type-testing requirements.
  • Third-Party Inspections: Fully accessible for client-nominated third-party inspectors (SGS, TUV, BV, Lloyds, Bureau Veritas).

In-House Testing Capabilities

Every transformer manufactured by Urja Techniques undergoes rigorous testing routines prior to dispatch, ensuring absolute compliance with IEC 60076 and customer-defined technical specifications.
