3.Key Features & Benefits
1. Built for Extreme Environments
- IP65+ Enclosure: Resists dust, rain, and snow.
- UV-Resistant Housing: Ideal for solar farms and desert installations.
- Anti-Corrosion Design: Stainless steel components for coastal/industrial areas.
2. High Accuracy & Low Loss
- ±0.5% voltage error ensures precise billing and grid stability.
- Reduced energy loss (<0.1W/kg) lowers operational costs.
3. Smart Grid Ready
- Embedded sensors enable real-time voltage monitoring for predictive maintenance.
- Compatible with IoT platforms like SCADA and EMS.
4. Low Maintenance, Long Lifespan
- Epoxy resin casting eliminates internal moisture, requiring no oil checks.
- 20+ year operational life with minimal degradation.
4.Real-World Applications
Be used in a wide range of industries.
Industrial Plants
Eliminate power factor penalties in CNC machines and assembly lines while handling surge currents up to 100x rated capacity.
Substation
Stabilizes substation voltage against harmonics and intermittent generation from renewable inverters.
Commercial Buildings
Retrofit aging systems in hospitals or malls with silent (<45dB), flame-retardant capacitors that meet NFPA 70 fire codes.
5.How It Works？
The 35kV Outdoor Voltage Transformer(Potential transformer) steps down high-voltage signals to safer 10kV levels for meters and relays. Its fully enclosed epoxy structure prevents partial discharges, while graded insulation handles transient surges up to 170kV.
6.Manufacturing Excellence
- ISO 9001-Certified Production: From raw material sourcing (Bayer epoxy, Hitachi steel) to final testing.
- Robotic Casting: Ensures void-free insulation for 100% dielectric integrity.
- 3-Stage Quality Checks: Impulse testing, partial discharge analysis (<5pC), and thermal cycling.
