Core Business & Products

Backed by robust R&D and manufacturing capabilities, we specialize in instrument transformers for medium and low voltage distribution networks (0.5kV–35kV). Our primary product matrix includes:

• Voltage Transformers (VT / PT): Covering 0.5kV to 35kV with cast epoxy resin dry-type insulation, engineered for metering (class 0.2S) and protection duties in switchgear and outdoor installations.
• Current Transformers (CT): Indoor and outdoor, single-phase and three-phase, including zero-sequence integrated units and low-voltage busbar types down to 0.66kV.
• Combined CT + VT Units: Voltage and current windings integrated in one cast-resin body — fewer panel penetrations and less wiring for compact switchgear.
• Cast-Resin Dry Transformers: Safe, flame-retardant, and maintenance-free solutions widely utilized in urban distribution networks and critical engineering projects.

Target Markets & Global Reach

Our products and engineering services strictly adhere to the highest international standards. Our business footprint spans the globe, deeply serving three core sectors:

• Global Power Utilities: Providing stable and reliable infrastructure equipment for national and regional grid operators worldwide.
• Substations: Supplying comprehensive equipment solutions for new construction, expansion, and technical upgrade projects of power substations.
• Heavy Industrials: Ensuring robust power reliability for energy-intensive and high-standard large industrial groups, including mining, petrochemicals, and metallurgy.
