　　Ports, docks, tunnels, and hospitals, requiring high reliability and fireproof performance.New Energy Sector

　　Photovoltaic step-up box transformers and wind farms, compatible with renewable energy grid connections.

　　V. Certifications and Standards

　　National Standards: GB 1094.11-2007, GB/T 22072-2008, GB 20052-2020 (Class II energy efficiency).

　　International Certifications: CE, UL (for some export models), compliant with IEC 60076-11 standards.

　　Safety Certifications: CNAS certification, passing type tests (short-circuit withstand, temperature rise, partial discharge, etc.).VI. Suppliers and Pricing

　　Price Fluctuation Factors:

　　Customization requirements (voltage class, protection grade, intelligent features)

　　Purchase quantity (bulk discounts)

　　Material costs (copper prices, silicon steel sheet price fluctuations)

　　Additional services (installation, commissioning, warranty period)VII. Maintenance and Care

　　Regular Inspections

　　Monthly checks on grounding resistance, lead terminal tightness, and insulation resistance (≥70% of factory value).

　　Semi-annual dust cleaning and testing of temperature controllers and fan functions.Overload Management

　　Avoid long-term overloading (recommended load rate: 75%-90%).

　　Emergency overloading must follow manufacturer's specifications, not exceeding 15% of rated load in summer and 30% in winter.Environmental Control

　　Maintain good ventilation, with ambient temperature ≤40°C and humidity ≤85%.

　　Avoid corrosive gases and conductive dust.Fault Handling

　　Immediately shut down for inspection in case of abnormal temperature rise or increased noise.

　　Conduct regular insulation resistance tests and partial discharge detection.Conclusion:

　　The SCB14-2000KVA dry-type transformer, with its high efficiency, low noise, fireproof, and intelligent features, has become the preferred choice for medium-to-large power distribution systems. Users should select suppliers with international certifications based on load characteristics, environmental conditions, and energy efficiency requirements, while focusing on the total cost of ownership (TCO). Regular maintenance can extend the service life to 30 years, ensuring long-term stable operation.
