• Junengda 300 kva Pad Mounted Transformer FAQ>>>

Q1: What are the key safety features of the Junengda 300 kVA pad-mounted transformer?

Junengda transformers prioritize safety with integrated arc-resistant tanks, fault-current protection, and corrosion-resistant enclosures. For fire prevention, our design includes robust overcurrent protection mechanisms—unlike systems that eliminate fuses, we use certified DC fuses with arc shields to isolate short circuits and avoid cascading failures .

Q2: How does this pad-mounted transformer ensure long-term reliability?

The product features a sealed tank to prevent moisture ingress and uses high-temperature insulation (Class H) to withstand overloads. Its corrosion-resistant stainless-steel enclosure endures harsh environments, while the oil preservation system minimizes oxidation, extending service life beyond 25 years .

Q3: Is the Junengda transformer compatible with smart grid monitoring?

Yes. It includes integrated sensors for dissolved gas analysis (DGA), enabling predictive maintenance by detecting early insulation degradation. Real-time data on gases like hydrogen and methane helps prevent failures, reduce downtime, and cut operational costs .

Q4: What installation requirements apply to this 300 kVA pad-mounted transformer?

Requires a level concrete pad (min. 150mm thickness) and clearance for ventilation/cable access. Junengda’s compact design simplifies placement in urban grids, rooftops, or industrial sites. Optional below-grade vaults are available for flood-prone areas.

Q5: How does Junengda address potential induced degradation (PID) in transformers?

Our units embed an active PID suppression module within the tank. This system continuously neutralizes electrostatic charges on windings and insulation, reversing existing PID damage and preventing power loss .

Q6: What maintenance does this pad-mounted transformer need?

Minimal maintenance is required. Predictive diagnostics via DGA sensors allow condition-based servicing, not rigid schedules. Remote alerts notify operators of gas anomalies, thermal shifts, or load imbalances for timely interventions .

Q7: Can it handle renewable energy integration, like solar farms?

Absolutely. The 300 kVA pad-mounted transformer supports bidirectional power flow and includes harmonic filtering to manage voltage fluctuations from solar/wind sources. Dedicated MPPT-compatible protection avoids backfeed damage .

Q8: What certifications does Junengda’s transformer hold?

Compliant with IEEE C57.12.20, IEC 60076, and CE standards. Rigorously tested for short-circuit endurance, temperature rise (<65°C), and seismic performance .
