Operational Durability

Extended Duty Cycle

• Continuous operation: 1 hour at 100% rated current & voltage

• Coil temperature rise <75K during operation

• Mandatory 12-hour cooling period after full-load operation

Stationary Casing Design

The robust stationary-type casing provides:

• Enhanced mechanical stability for industrial environments

• Optimal gas containment for consistent insulation performance

• Single-phase configuration for simplified installation

Industry Applications

• Power Utilities: Transformer and circuit breaker testing

• Manufacturing: Quality control of high voltage components

• Transportation: Railway electrification system maintenance

Why This Transformer Stands Out

1. Superior Insulation: SF6 gas technology eliminates oil maintenance

2. Precision Measurement: ≤3% waveform deviation ensures accurate results

3. Industrial Grade: Designed for heavy-duty testing cycles

4. Safety Compliant: Meets international HV testing standards

5. Eco-Friendly: Minimal SF6 leakage reduces environmental impact

For power plants, electrical manufacturers, and testing laboratories requiring reliable 250KV testing capacity, the HGTS series delivers unmatched performance in a maintenance-free package.
