FAQ:
-
Q: What does "Door Type" mean for this transformer?
A: "Door Type" refers to a specific structural design where the transformer tank features large, accessible doors. This allows technicians much easier entry for internal inspection, maintenance, and repair of core/coil assemblies compared to conventional designs with smaller manholes, significantly reducing downtime. -
Q: Is this transformer suitable for both wind AND solar applications?
A: Yes, our HV Door Transformers are specifically engineered to handle the unique challenges of both wind farms (variable load, potential harmonics) and large-scale solar PV plants. They efficiently step up the generated voltage (e.g., from 0.69kV turbine output or PV inverter output) to 6kV, 10kV, or 12kV for grid connection. -
Q: What certifications do these transformers hold?
A> Our manufacturing facility is ISO9001:2015 certified, ensuring a consistent quality management system. The transformers themselves are designed and tested according to relevant international standards like IEC 60076 or IEEE C57.12. Specific test reports (e.g., routine, type) are provided. Note: Final certification markings (like CE) depend on specific project requirements and destination market regulations, and can be arranged. -
Q: How do I choose between 6kV, 10kV, and 12kV?
A> The required voltage rating depends on your specific project's grid connection voltage and the output voltage of your wind turbines or solar inverters. Consult your project specifications or grid interconnection agreement. We can advise based on your application details. -
Q: Can you provide transformers with On-Load Tap Changers (OLTC)?
A> Yes, while standard models usually feature Off-Circuit Tap Changers (OCTC), On-Load Tap Changers (OLTC) are a crucial option for applications requiring voltage regulation without interrupting power supply, especially common in wind/solar integration. OLTC can be supplied upon request. -
Q: What is the typical lead time for a custom transformer?
A> Lead times vary based on the complexity of the design, capacity, and current factory load. For standard designs, expect approximately 8-12 weeks. Custom or large-capacity units may require 12-20 weeks. We provide firm lead times upon order confirmation. -
Q: Do you offer installation supervision or commissioning support?
A> While the transformer price typically includes factory testing and standard documentation, on-site installation supervision and commissioning support are valuable optional services we can provide. Please discuss your specific requirements with our sales team. -
Q: What warranty do you offer?
A> We provide a standard warranty period of 12 months from the date of commissioning or 18 months from the date of shipment, whichever occurs first. Extended warranty options may be available.
