    FAQ

    Q1: What is the difference between a dry-type and oil-filled substation?

    A: Dry-type transformers use resin-encapsulated windings, offering higher fire safety, no oil leakage, and lower maintenance. They are ideal for indoor or environmentally sensitive areas.

    Q2: Can this substation be used for solar energy storage systems?

    A: Yes, the SCB dry-type box substation is widely used in solar PV and energy storage projects for stepping up voltage and integrating with the grid.

    Q3: What is the lead time for a 630kVA unit?

    A: Standard lead time is 25-35 days after order confirmation, depending on customization requirements. We offer expedited shipping for urgent projects.

    Q4: Do you provide installation and commissioning support?

    A: Yes, we provide detailed manuals, remote guidance, and optional on-site technical support for large orders.

    Q5: What certifications do your substations have?

    A: Our products are CE, ISO 9001, and IEC certified. We can also provide test reports from third-party labs upon request.
