FAQ
Q1: Can it operate normally in extreme temperature environments?
A: Yes. Adopting special insulating oil and optimized structural design, it maintains stable performance in high temperature, low temperature and high humidity outdoor environments.
Q2: What safety measures are required for installation?
A: According to national and industrial safety standards, it is necessary to set up oil containment pits, firewalls and isolation zones; install temperature monitoring, oil level monitoring, oil leakage alarm and pressure relief devices; and configure professional fire-fighting equipment to ensure safe operation.
Q3: What are the core advantages of large three-phase oil-immersed transformers?
A: 1. Large capacity: Meet the demand of large-scale power supply and long-distance transmission; 2. High efficiency: Adopt optimized core and winding design, low energy loss and energy saving; 3. Stable operation: Mature structure, strong overload capacity and long-term stable operation; 4. Strong adaptability: Adapt to various harsh working environments and grid conditions.
